How does reading about these three different kinds of owners, one after the other, affect your response to each owner?

Francois and Perrault value Buck for his strength and eventually come to hold him in high esteem because of his amazing ability to lead the team and do their work for them. They lack any significant personal attachment to him, however, as they see all their dogs as tools that they must take care of in order to do the work they've chosen. They know to take care of them and feed them and rest them when needed.


When Buck falls into the clutches of Hal and Charles, they have no idea of how to take care of the dogs and expect them to have limitless strength. They drive the dogs until they can no longer stand. This exposure to human stupidity and pride perhaps starts Buck down the road to being totally wild and free from the vagaries of human ownership.


The juxtaposition of Hal and Charles' treatment of Buck with the way that John Thornton treats him serves to highlight the incredible love and devotion that John gives Buck. Buck returns this affection even when he is torn between the world of the wolves and the comfort and care he feels from John. That same contrast makes it easy for the reader to sympathize with Buck when he finds that John has been murdered and he turns on the murderers.

Give a short biography of the 37th U.S. President, Richard Nixon.

Most American presidents come from families that are either rich or, at the very least, comfortably well-off.  Richard Nixon was different than most American presidents in this way. He ended up being very different from all other American presidents as he was the only one (so far) to have been forced from office in the middle of a term.


Richard Nixon was born in 1913.  His parents had a small lemon farm that failed while Nixon was a child. They then had a family store in which all family members worked.  The family was so poor that Nixon had to turn down a scholarship to go to Harvard because the family could not afford the cost of getting him to and from Massachusetts.  Nixon ended up attending Whittier College in California. After graduating, he got a full scholarship to attend law school at Duke University, where he got a degree in 1937.


Nixon returned to California to practice law.  He married Thelma Ryan (better known as “Pat) in 1940. Nixon volunteered for military service and served in the Navy in WWII. 


After the war, Nixon ran for and won a seat in Congress in 1946. He left the House and won a Senate seat in 1950.  In 1952, he was selected as Dwight D. Eisenhower’s running mate and served as Vice President from 1953 to 1961.  He was selected largely because he had made a name for himself as a fierce anticommunist.


Nixon ran for President himself in 1960 but lost to John F. Kennedy. He spent 8 years out of office practicing law, but then returned to politics and won the 1968 presidential election. He was reelected in 1972. In 1974, Nixon was forced to resign from office because of his involvement in the Watergate scandal. Like most ex-presidents, Nixon traveled, gave speeches, and wrote books.  He died in 1994.

If 10mg of drug "x" exerts the desired pharmacological effect, but 160 mg of "x" is a fatal dose, what is the therapeutic index of "x"?

The therapeutic index of a drug is also known as the therapeutic window or safety window, and compares the therapeutic effect of a drug with the amount related to toxicity or adverse side effects.


This is calculated as TD50:ED50. TD50 refers to a dose of the drug that causes toxicity or adverse side effects in 50% of the subjects. ED50 refers to a dose of the drug that leads to the desired pharmacological outcome in 50% of the subjects. This means that drugs with higher therapeutic indices are preferable because it requires a low dosage for efficacious results and/or a high dose for side effects to occur. This is referred to as a large therapeutic window because there is a large dosing margin where the drug can be administered without causing undesired side effects.


For drug "x" in particular, the therapeutic index will be 160mg:10mg, which is equal to a 16:1 ratio.

Can somebody tell me one helpful and one harmful bacteria in or on the human body?

A Bacteria that is helpful:


E.Coli is a type of bacteria that is helpful to humans. It is a bacteria that is found in the intestines, and helps  with the breakdown and digestion of the food that a person consumes.



A bacteria that is harmful:


An example of harmful bacteria is Staphylococci. It affects humans by causing problems with their skin. Problems include boils, pustules and abscesses. This bacteria further causes other problems such as infections in the bones, joints and wounds - which are very painful. This bacteria can also enter the joints and heart valves (seldomly occurs though) during an operation (surgery) can be life threatening due to the severe infection it may cause. 



SUMMARY:


Bacteria helpful to humans: E.Coli


Bacteria that is harmful to humans: Staphylococci

Describe the two children who emerge from the second spirit's robe in A Christmas Carol by Charles Dickens.

In A Christmas Carol by Charles Dickens, near the end of the second spirit's visit, two children emerge from beneath the folds of his robe. Scrooge asks about them because he sees something under the robe, and the Ghost of Christmas Past reveals them. 



"From the foldings of its robe, it brought two children, wretched, abject, frightful, hideous, miserable." (Dickens 85)



Dickens goes on to describe them as a boy and a girl.



"Yellow, meager, ragged, scowling, wolfish; but prostrate, too, in their humility. Where graceful youth should have filled their features out, and touched them with its freshest tints, a stale and shriveled hand, like that of age, had pinched and twisted them, and pulled them into shreds." (Dickens 86)



The children represent "Ignorance and Want." Dickens is bringing home the point that when society does not educate its youth, nor take care of its poorest citizens, society is doomed. When Scrooge asks if they have no help, the Ghost of Christmas Past returns Scrooge's own words to him,



"'Are there no prisons? Are there no workhouses?" (Dickens 87)



In doing so, he reminds Scrooge that he is part of the problem. Scrooge would rather people be thrown into prison than give them charity.

Describe the reception Daniel receives from Joel and Malthace.

Daniel’s parents and uncle die when he is young. His father and uncle die at the hands of the Romans and his mother passes on from grief and illness caused by the death of her husband. Daniel hates the Romans and vows to kill them. Daniel and his sister, Leah, are taken in by their grandmother, but because of abject poverty, Daniel is sold as a slave to Amalek. Daniel escapes slavery and joins Rosh, a rebel leader, based in the mountains around Galilee.


While out on his duties, Daniel notices two figures close to the mountainside and later recognizes the two as Joel and Malthace, children of a Rabbi in his hometown. Daniel makes contact with the two siblings. Joel and Daniel bond over their hatred for Romans and the need to support Rosh in his fight against them. Joel and Malthace receive an opportunity to meet Rosh. Rosh invites Joel to stay, but he declines because he needs to take his sister back home.


Later, Rosh sends Daniel to find Joel because they need his help. Daniel arrives at Rabbi Hezron’s place, and although Joel does not hesitate to welcome his friend, Malthace is reluctant in receiving Daniel at their home.


In summary, it is a mixed reception for Daniel. His friend is happy to see him, but the same cannot be said for his sister.

How was Anne Frank not a hero?

Anne Frank was a victim of Nazi atrocities, but she serves as an inspiration to many.


I recently heard an Auschwitz survivor speak. He was talking to a group of seventh and eighth graders. He said, “Anne Frank was not a hero. She was a victim.” This man, who had been through horrors similar to Anne’s, was not seeking to diminish her memory. He just wanted the class to understand that Anne should not have had to suffer.


What is a hero? A hero is someone who helps others or inspires others. By this token, Anne is a hero. She has served as an inspiration to many through her published diary. Anne would have liked the fact that her diary is so widely read. She wanted to be a writer.



It's much easier now to tell Peter things I'd normally keep to myself; for example, I told him I want to write later on, and if I can't be a writer, to write in addition to my work. (Saturday, March 25, 1944)



Anne’s diary shows the triumph of the human spirit. She was locked up, fearing for her life and in hiding day after day. Yet Anne and the others persevered. They lived their lives with as much normalcy as they could. Anne did everything she could to brighten the lives of those around her. In that sense, she was a hero.


Heroism is really in the eye of the beholder. A person who hides from the Nazis is brave, in my book. Anne and her family did not give up. They fought back against oppression in the best way they knew how. Because of this, Anne and her family lived a little bit longer. Anne also was able to write about her experiences, which her father published to serve as an inspiration to others.

How does the importance of family help the reader connect to the story Night by Elie Wiesel?

Family is something that most people have experience with and strong feelings about. Even if we have disagreements or suffer hardships with our parents, grandparents, and siblings, we are bound to them and feel a sense of obligation to them. Throughout Night, Wiesel and his family are taken from the Jewish ghetto they lived in and sent to Auschwitz-Birkenau. Amidst all of the violence and insecurity of the Holocaust, Wiesel's family remained a constant for him. In being moved from ghetto to ghetto, they were still together as a family. In spite of all the terrible things happening, at least that one thing was constant. Family can offer a sense of stability and reaffirm our identities even in the most troubled of times, which is why it is all the more unfortunate that Wiesel lost his mother, sister, and father in the concentration camp. 


Upon arrival, Wiesel's mother and sister were separated from him and killed, while he and his father were sent to labor. By the end of the book, Wiesel's father died due to malnutrition and dysentery. Wiesel's world changed dramatically not only for the fact that he had been sent to a concentration camp, but that the one constant he had relied on was taken from him. Such a message really hits home, as most of us can understand and appreciate the stability family offers in trying times.

How does Orwell use the symbol of the memory holes to deepen the aesthetic impact of the novel and develop the theme?

In Part One, Chapter Four, of 1984, the reader is first introduced to the memory hole. These holes are prevalent in the Ministry of Truth, where Winston works, and are used for destroying scraps of paper. These scraps, however, contain documents from the past and are transported via the memory hole to the "enormous furnaces which were hidden somewhere in the recesses of the building."


The memory hole, then, is a symbol of the party's control over information. As we see in Chapter Four, Winston destroys documents from the past, like the claim that the party would not reduce the chocolate ration, and replaces them with party-approved information. In the case of the chocolate ration, for instance, Winston creates a new document which states that a ration would "probably be necessary in April." This not only boosts the prestige of the party but also makes it appear as though Big Brother has the interests of the people at heart. 


In the wider context of the novel, the memory hole also represents the party's ability to control the past. By destroying memories and installing new ones, the party moulds and shapes popular understanding of Oceania's history. The problem with accepting the party's version of history, however, is that people will come to accept anything that the party tells them.


Like Winston says, in Part One, Chapter Seven, if the party declares that "two plus two equal five," then, sooner or later, one has no choice but to believe it.

What effect did Napoleon have on France in 1800?

In 1800, after more than a decade of instability following the first French Revolution, and after the establishment of the ineffectual Directory, which ruled France from 1795 to 1799, Napoleon staged a coup and replaced the Directory with the Consulate, a centralized, semi-authoritarian government with certain liberal characteristics that provided a modicum of political and economic freedoms to the populace and stability to the economy. The Consulate was compromised of three "Consuls," or leaders, otherwise known as the Triumvirate, based on the Roman system. The three consuls were: Jean Jacques Régis de Cambacérès, Napoleon Bonaparte and Charles-François Lebrun.


Napoleon and his co-consuls set up the new government as a republic, with three legislative assemblies (the Council of State, the Tribunate, and the Legislative Assembly) each given various degrees of power and differing responsibilities. This was an attempt to achieve a separation of powers, based in part on the American system, but also a very clever way to make sure that none of the legislative branches could accomplish much on their own.


Napoleon and his co-consuls also reinstated the popular vote, but the will of the people was diminished because a group of "notables," or pre-eminent members of society, were given greater authority to shape policy, and had been handpicked by the senate, so that these elected officials mostly towed the line of the Consulate, for fear of losing their positions and influence if they did not. In essence, the popular vote and the tri-cameral legislature were window dressing, allowing Napoleon's decision making to seem more democratic than it actually was. That said, Napoleon was actually very popular with the general public, because he restored order to a system of chaos, brought about real economic and political reforms, and proved a fearsome military leader, bringing glory and vast new territories (and revenue) under French control.


After four years of the Consulate, however, with his popularity among the French people soaring ever higher, Napoleon stopped trying to hide his true intentions, and disbanded the republic in order to become Emperor in 1804.

What were some major changes in living and working conditions as a result of the Industrial Revolution?

The Industrial Revolution began in America in the 1790s. Over the next four decades, the American economy became increasingly mechanised with production moving from the country to the rapidly-expanding towns and cities. This had a dramatic impact on the way that people lived and worked. It brought about the rise of the factory system, for example, where work was performed on a large scale in a single location. Factory work also led to the rise of wage labour, but the low wages and long hours of the factories exploited workers. Over the course of the century, the trade unions and strike action would become a common feature of industrial life. 


As people flocked to the towns and cities for work, many of them lived in cramped and overcrowded conditions. Slums were rife in cities like New York and exacerbated by a population boom and the high number of immigrants who came to America in the 1800s. (The population of America quadrupled between 1814 and 1860, to over 31 million people.)


Of course, there were some people who benefited from the Industrial Revolution. Many merchants and bankers became extremely wealthy from these new methods of production. People also enjoyed the abundance of manufactured good which were available to purchase. But it is important to remember that not everybody shared in these financial and cultural successes.

In what line (please provide the line number) does someone in Romeo and Juliet say " I should have acted more strange" ?

Juliet utters the line, "I should have acted more strange" in line 102 of Act 2, Scene 2.  She is not talking about strangeness in the modern context; rather, she is stating that she should have been more distant or a bit more hard to get, rather than voicing her feelings out loud for anyone (including Romeo) to hear.  She is both embarrassed at having been overheard and concerned that Romeo will not take her professions of love seriously.


Romeo responds by swearing on the moon, which Juliet rejects based on the moon's ever-changing nature.  Eventually, their conversation finds its cadence and becomes more passionate; by the end of this exchange, they have agreed to a secret wedding to take place the following day.

What are the layers of the atmosphere?

On what page is this passage in Fahrenheit 451?"Do you ever read any of the books you burn?"He laughed. "That's against the law!""Oh. Of course."

This dialogue is in the exposition of Fahrenheit 451 on page 8 for some publications, and on page 5 of the Simon & Schuster paperback.


In Part One "The Hearth and the Salamander," Montag walks home from his job as a fireman and senses that the "air seemed charged with a special calm" as though someone were waiting; then, he encounters a girl who walks as though the wind and blowing leaves carry her along. Montag is taken by the vision of this strange girl.


After asking his name and introducing herself, she engages him in conversation, telling him how much she enjoys the outdoors as she sometimes walks all night and then watches the sun rise. Clarisse McClellan asks Montag how long he has been a fireman and if he ever reads any of those books that he says he enjoys burning. When she says, "Oh. Of course," Montag adds, 



It's fine work. Monday burn Millay, Wednesday Whitman, Friday Faulkner, burn 'em to ashes, then burn the ashes. That's our official slogan."



Clarisse, however, is not impressed. Instead, she asks Montag why he laughs when she has not said anything funny, hinting that his laughter may be disguising some other feelings of Montag.


This quote about reading books being against the law is powerful because literature is the record of human experience and people's connection to the ideas and emotions of the past, experiences to which others can relate as well as learn. Without books, there is no past, no history.  People are isolated in their thoughts in the society of Fahrenheit 451 with nothing by which to measure life.

What is a respiration challenge monkeys face in comparison to fish? A) Dry air makes it a challenge to keep respiratory structures moist. B) The...

Of the answers listed, the first one, letter (A) makes the most sense.  "Dry air makes it a challenge to keep respiratory structures moist" would be a decided disadvantage against fish, who inhabit aquatic environments.  Fish use gills to extract oxygen from water.  The water is allowed to flow over the gills, so the gills have an unending moisture supply to keep them hydrated.  Monkeys have to depend on the humidity factor of air to help keep the interior of their lungs moist.


It wouldn't be letter (B), as most lung structures in land animals are larger when compared to the fish's gills.  Answer (C) is not a good choice either; air is certainly not denser than water, it is less dense and diffuses with relative ease across the alveoli structures within lungs.  Answer selection (D) is off-base as well, air actually contains more oxygen than water and is easier to extract by breathing processes conducted by land-dwelling animals like monkeys.

`u = , v = ` Find `u*v`.

You need to evaluate the product of the vectors `u = u_x*i + u_y*j, v = v_x*i + v_y*j` , such that:


`u*v = u_x*v_x + u_y*v_y`


`u*v = (-2)*(-1) + 5*(-8)`


`u*v = 2 - 40`


`u*v = -38`


Hence, evaluating the product of the vectors `u = u_x*i + u_y*j, v = v_x*i + v_y*j,u = <-2,5>, v = <-1,-8>` , yields `u*v = -38.`

What metaphors should I use to describe an elderly man's face?

To really nail this down, think about what kind of elderly man you're talking about. Is he wise, like an old tree or an owl? Or is he slack and tired, like an old shoe? 


Is his skin deeply wrinkled, like a raisin or a walnut? Or is does it have thick, deep lines like carved wood?


Is he smiling and content? Frowning and sad? Think about your character, picture him in your mind, and then think about what the picture reminds you of. Have fun with it!

Was it right for the United States to enter the Vietnam War?

The answer to this question is a matter of opinion. So I will discuss the reasons people supported and opposed the war. 


Those who supported the war viewed Vietnam as another front in the Cold War. They thought that if the spread of communism was not resisted, that it might spread throughout Southeast Asia and even to places like India and Indonesia like, according to a theory of the time, "dominoes." They thought the United States had a moral obligation to support the people of South Vietnam, who were in danger of having a Communist regime imposed on them by the North and by the Vietcong. Even most opponents of the war would have admitted that if the United States simply stood on the sidelines, South Vietnam would inevitably fall to communism. Even after the fact, some people argue that American intervention in Vietnam slowed the spread of communism by demonstrating American resolve to fight against it.


Opponents of the war tended to argue that the United States had no business intervening, especially militarily, in the affairs of countries on the other side of the planet. To them, the war was an example of American imperialism, not altruism or even wise Cold War strategy. Others argued that without a full-scale intervention, the war in Vietnam would not be successful. Still others, especially after the fact, pointed out that while North Vietnam was communist, the war in the region was best understood as a nationalist conflict that was aimed as much at establishing a Vietnamese nation as at spreading Communism around the world. It was not part of a global Communist plot, and this way of thinking led many way planners to underestimate the commitment of the North Vietnamese and the Vietcong as well as the support for the VC in South Vietnam.

What kind of mood or atmosphere does the setting suggest?

The short story, “The Pedestrian” takes place in November of 2053 in a large city at night.  From the very beginning, Bradbury sets the mood of the story through his descriptions of the houses and environment as Leonard Mead is taking his nightly walk alone in the city.  First of all, the evening is “misty” and eerily “silent."   Mead walks on a “buckled sidewalk” (showing lack of use and repair) and notices the dark windows of the homes he walks by.  He feels as if he is walking through a “graveyard.”  He says, “Sudden gray phantoms seemed to manifest upon inner room walls where a curtain was still undrawn against the night, or there were whisperings and murmurs where a window in a tomb-like building was still open.”  The homes are dark, and the light from the television casts shadows of those watching it on the walls. These descriptions set up a creepy, suspenseful mood, as we know that Mead is outside and alone in the city.  The “death” motif carried throughout the story also adds to the mood of the story. In addition, Bradbury repeats the words “silent” and “empty” throughout the story to again create a mood.


In the end, Mead is picked up by the robot police car for walking at night and was taken to The Psychiatric Center for Research on Regressive Tendencies where he will be reprogrammed to fit into the society whose obsession with television controls their lives. Bradbury ends the story with a mood that shows the anxiety (note how many times he uses the word, “empty” in the last paragraph) of what happens when technology takes over our lives.

In what chapter does David Strorm run from his father in the book The Chrysalids?

 David runs away in Chapter 12.


David’s father Joseph Strorm is a passionately religious man.  He rules his domain with an iron fist.



He was still the largest landowner, he still continued to preach frequently on Sundays and to explain with practical clarity the laws and views held in heaven upon a variety of matters and practices, and, upon the appointed days, he administered the laws temporal, as a magistrate. (Ch. 2)



David is not as staunchly religious as his father.  He does not really believe in the True Image.  When he meets and befriends a girl with extra toes, he does not consider it sacrilege.  His father would never allow it.  David understands what it is to be different.  He is a telepath, and he and the other telepaths live in constant fear that they will be discovered. 


The beginning of the end is when David’s friend with the extra toes, Sophie, is discovered.  David tries to protect her, and holds out as long as he can against his father’s beating.  Sophie is caught, sterilized, and sent to the badlands in the Fringes.  This is where all of Waknuk’s outcasts are expelled to. 


Somewhere in the back of his mind, David must have always known he would someday be expelled.  His father would not protect him.  Even his own uncle was expelled.  Family means nothing when it comes to the True Image.  As soon as it is discovered that David is telepathic, that is it.  He and the other telepaths have to run for their lives to the Fringes. 


It happens when David’s sister Petra calls the others to her with psychic screaming after her pony is attacked.  The telepaths gather, and when a man finds them together he doesn’t buy their explanation that they heard her screaming.  David tries to explain to Petra using words that she has to be careful.  Uncle Axel, who knows about David, warns him that people have been asking questions. 


Soon, two of their own are captured—Sally and Katherine.  They have to flee before they are all caught.  Michael explains how dangerous the situation has become. 



Frankly, David, you're going to need your wits, too. There's hell to pay over this. They must have found out much more about you than we ever guessed, though they aren't on to Mark or Rachel or me yet.  But it's got them very worried indeed. They're going to send posses after you. (Ch. 12)



Things get only worse from there.  Waknuk is dangerous because they are being hunted, but the Fringes are dangerous too, because they are ruled by David’s uncle, whom he calls Spider.  He was the one expelled years before.  He is not happy about the new heat David's band brings on him.

What does Gatsby hope to attain by repeating the past?

Since Gatsby met Daisy, while he was a soldier during World War I, she has been his dream.  All of his efforts since have been with this in mind.  All of his wealth has been acquired so he can win her, believing that it is only his lack of wealth that caused her to marry Tom Buchanan instead of him. He loves her and believes that she loves him.  For Gatsby, she is the American Dream.


Gatsby wishes to repeat the past so that he can win Daisy again. When Nick tells him he cannot repeat the past, "Gatsby cried out incredulously, 'Why of course you can'" (116) and looked about "wildly, as if the past were lurking here...just out reach of his hand" (116-117).  He says,"I'm going to fix everything just the was before"(117).


Gatsby cannot afford to believe that he cannot repeat the past because his entire being is consumed with having Daisy, and if he cannot go back somehow, he cannot have her and cannot get his life back. He conveniently disregards the fact that she has chosen to marry Tom Buchanan, with his buckets of money, rather than waiting for Gatsby, that she has a young child, and that there is no "do over" for his or her life.  Daisy is his dream, and he is blinded by it. As Nick says, "he wanted to recover something, some idea of himself perhaps, that had gone into loving Daisy" (117).


Gatsby is a fool, but he is a heroic one, always true to his vision of a dream, and at the end, sacrificing himself for his dream of Daisy.

The unknown liquid is methanol and its density is 791 kg/m^3 at 25 degree C. What is your percent error in the experiment?

When we carry out experiments, we obtain some parametric values and these measured values are compared against the standard or accepted values. The percentage error in the parametric values is determined by comparing the measured and accepted values as:


% error = ([measured value - accepted value] / accepted value) x 100


Thus, we need both the measured value and the accepted value for determining the percentage error. In the given question, only the accepted value (791 kg/m^3) is given and the measured value is missing. In absence of complete data, we cannot determine the % error.


For example, if you measured a value of say, 790 kg/m^3 as the density, then the % error in your experimental value is:


% error = ((790 - 791)/791) x 100 = 0.126% 


That means you measured a slightly different (in this case smaller) value of density as compared to the accepted value.


Hope this helps.

In The Sign of the Beaver, after his day of fun at the Indian village, Matt eagerly waits for Attean to come back. Why doesn't Attean immediately...

Matt's day of fun at the Indian village after he saved Attean's dog from a trap, left him feeling as if he was finally accepted by Attean and his tribe. His grandmother was impressed he had saved the dog. Matt joined other boys from the tribe in several games. When Attean left Matt to walk the remainder of the way home alone, Matt felt that he had finally earned Attean's respect.


However, when Attean did not come back to the cabin after a week, Matt grew concerned. When Attean did finally return, he had a serious demeanor. He revealed to Matt that it was time for him to go on a journey to find his manitou, or spirit. This rite of passage would help Attean to become a man and hunter. Attean explained that it was an important part of his Indian culture. When Matt next saw him, Attean had a changed, more mature demeanor and appearance.

What are the similarities and differences of reflection and refraction? thanks

Reflection and refraction are both behaviors of waves , such as light and sound waves.  


To “reflect” means to “bounce off of”. Reflection of light occurs the best off of smooth, hard, and shiny surfaces. When bouncing off of such surfaces, light reflects in the same angle as it hit the surface. Shiny, rough surfaces cause light to reflect in all directions. This is referred to as the “scattering” of light. Reflection of light decreases on opaque, rough surfaces.


Echoes are reflections of sound waves. Sound echoes the best off of smooth, hard surfaces. This is why your voice echoes well off of the walls and floors of a gymnasium. Sound does not echo well off of a soft, rough surface. This is why your voice does not echo in a carpeted living room.


Refraction is the bending of a wave as it enters a medium that causes the wave’s speed to change. As light enters from a fast medium into a slow medium, the light wave bends toward the normal to the boundary between the two media.

What is Macbeth's tragic flaw in Act I?

In Act 1, Scene 7, Macbeth delivers a soliloquy in which he considers all of the reasons he has not to commit the murder of Duncan as well as the one reason he has to move forward with this crime. He says, "I have no spur / To prick the sides of my intent, but only / Vaulting ambition, which o'erleaps itself / And fall on th' other--" (1.7.25-28). So, while he has a great many reasons to justify not committing the murder, he has only one reason to go through with it: ambition. However, when Lady Macbeth enters the room, just at this moment, he immediately says to her, "We will proceed no further in this business" (1.7.34). Thus, it seems to me that ambition alone is not enough of a catalyst to prompt him to take action because almost as soon as he identifies it, he tries to cancel their plans.


It is only when Lady Macbeth wounds his pride, mocking his bravery and manhood, that he relents. She insists that, if he will not murder Duncan to take the throne, he will have to "live a coward in [his] own esteem," and that when he made the promise to her that they would proceed with their plan, "then [he was] a man" (1.7.47, 56). She implies that he is not a man if he breaks this promise and swears that she would be willing to kill her own child if she had promised him to do so. Thus, it is only when his pride is wounded that Macbeth finally commits fully to the plan to murder Duncan, and so I argue that pride is his true tragic flaw, not ambition.

What is the role of women in As For Me and My House?

As For Me and My House by Canadian author Sinclair Ross was first published in 1941 and reflects the position of women in Canadian society during the period just before the second world war. Set during the Great Depression, the novel is the story of the lives of Mrs. Bentley, the protagonist and viewpoint character, and her husband Philip, a minister of the United Church in a small town of Horizon. The title emphasizes the way religion has become not so much a calling as a duty to the couple; it is taken from a Biblical passage: 



And if it seem evil unto you to serve the Lord, choose you this day whom ye will serve; whether the gods which your fathers served that were on the other side of the flood, or the gods of the Amorites, ... but as for me and my house, we will serve the Lord. (Joshua 24:15)



This suggests that there is a religious rationale for both Mr. and Mrs. Bentley to suppress their own talents, interests, and desires in favor of serving the church. This is even more the case for Mrs. Bentley as she is doubly subordinated both to the church and the interests of her husband. She suggests that her marriage has deprived her of the opportunity to pursue her career in music:



Before I met him I had ambitions too ... But he came and the piano took second place ... I forgot it all, almost overnight ...  For right from the beginning I knew that with Philip it was the only way. Women weren't necessary or important to him ... Submitting to him that way, yielding my identity -- it seemed the way life was intended ....



The society described is a patriarchal one in which women are subordinated to men. Both Mrs. Bentley and Judith have as their roles primarily catering to masculine needs. Although parishioners enjoy Mrs. Bentley's piano playing, it does not provide her with a career or the economic independence that would make her marriage more equal. She is also judged as a failure by the ladies of the parish because of her inability to provide children for her husband. Her subordination is emphasized by the fact that we do not discover her first name but that she is only known to us as Mrs. Bentley, the wife of Philip.

Discuss the roles of Vladimir and Estragon in Beckett's play, Waiting for Godot.

This famous pair, also known as Didi and Gogo, play a central role in Beckett’s stage attempt to “eff the ineffable” through the use of all the languages of the stage – dialogue plus costume, proxemics, gesture, etc. In their stage personas, they are two wandering hobos seeking not only shelter, food, and protection from bullies, but also waiting to be contacted by some scarcely described "character" named Godot, who has some task or direction for them. The two hoboes are inseparable in their quest, “passing the time” with conversation, sometimes insults, sometimes debates about their reality, and sometimes just with utterances to “pass the time.” Didi seems to do the thinking, and Gogo seems to deal with their physical dilemma; these two “roles” are physically represented by Didi’s obsession with hats and Gogo’s obsession with boots. In the symbolic roles of existentialism, they represent the two aspects of Man, his consciousness and his facticity in the physical universe.

Imagine that you are Gregory from Romeo and Juliet and you have been imprisoned for taking part in the play's initial fight. How would you write...

Just to be clear, Gregory is not actually imprisoned after the fight in question. However, it appears your teacher wants you to imagine that he was, there are several arguments you could use.


The first is that you were simply defending the Capulet name. As a loyal servant of a respected house, defending the family name would have been a positive thing.


Second, you could argue that the Montagues started the fight, and that you were simply acting in defense.  In reality, your buddy Sampson bit his thumb at the Montagues, which is the Shakespearean equivalent of giving the middle finger.   This no doubt provoked the Montagues.  However, you could argue that the Montagues started the physical fighting when they responded to the initial thumb biting.


If you really wanted to save yourself, and if you were willing to throw Sampson under the bus, you could argue that it was Sampson who was the true aggressor.  After all, you were simply going to frown at the Montagues, but Sampson heightened the insult by thumb-biting.  You could argue that you simply got pulled into a fight based on the impulsive actions of your companion, Sampson.


The entire fight appears in Act 1, Scene 1, so it might be worth a revisit. Hopefully, this gave you a jumping off point for some ideas.

What are some of Heck Tate's characteristics in To Kill a Mockingbird?

Heck Tate is forty-three, a lifelong resident of Maycomb County, and takes his job as sheriff seriously. 


Here are some character traits of Heck Tate:


Practical


  • When Sheriff Tate receives the call on the rabid dog traversing the street on which the Finches live, he arrives, accompanied by Atticus, who has come from his office. They wait until the dog comes into range for a good shot. When the dog heads toward the Radley house, Mr.Tate insists Atticus shoot the dog, tossing him his rifle even though Atticus says he has not fired a gun in thirty years.


"For God's sake, Mr. Finch, look where he is! Miss and you'll go straight into the Radley house! I can't shoot that well and you know it!"

Tate's practicality is the key to the success of the situation as Atticus fires a perfect shot.



  • In another instance of his practicality, Heck Tate chooses not to arrest Boo Radley for stabbing Bob Ewell as he threatened Jem's life, reasoning that it serves no good purpose to expose the shy recluse to publicity and scrutiny when Ewell is already dead. Tate chooses to bring fairness to prominence over textbook law enforcement. 

Conscientious and Courageous


  • Despite his doubt in the honesty of Bob Ewell, Sheriff Tate is duty-driven when he answers the call to come to the Ewells' home, where Mayella supposedly has been raped. He arrests Tom Robinson, as is his duty.

  • Whenever duty demands he be there, Tate is. He goes with the men who come to the Finch home to ask Atticus to obtain a chain of venue, is at the jailhouse where Tom is held before the trial, and testifies honestly during Tom's trial.

Average in Intelligence but always Honest


  • While he usually performs his job well, Sheriff Tate allows himself to be deceived by the Old Sarum Bunch, who trick him into leaving the jailhouse on a bogus call.

  • When Tate testifies at Tom Robinson's trial, Atticus questions Tate and leads him to understand that he assumed some things that were not necessarily true. For instance, Atticus asks the sheriff about the attack upon Mayella. Tate says there were already bruises appearing on her arms, "and it happened about thirty minutes before—" Here Atticus interrupts, asking, "How do you know?" Mr. Tate smiles in humility, "Sorry, that's what they said."
    Further, as he questions the sheriff, Atticus leads Heck Tate to realize Mayella was struck in the face by someone who is left-handed. This fact, of course, is crucial to Atticus's attempts to prove Tom, whose left arm is withered and useless, could not have struck Mayella.

Sheriff Heck Tate is a small-town sheriff, but he is not among the many in his position who are mere pawns of the area's businessmen and politicians. He is honest, duty-driven, stalwart, and genuine.

What is the use of local color in the novel A Tale of Two Cities?

The setting of London is presented in shades of black and white. The area of Soho, where Doctor Manette and Lucie live after their return to England, is pictured as shadowed. It is also symbolic of the extremes of opposites that occur from the very first paragraph. The Manettes’ house is set off the street into a shady courtyard with a plane tree under which they often sit. The shadows become symbolic of the coming catastrophe of the French Revolution, lurking their way to the Manettes, planning to draw them into the darkness away from the light of their happy lives.


In Paris, red is a frequently used color, symbolizing the blood that will be shed by the revolutionaries. At the breaking of the wine cask in the street, Gaspard uses the red wine to write the word “Blood” on the wall. Defarge erases it with mud, warning Gaspard that the time for blood will come, but it is not now. The red of the rose in Madame Defarge’s turban also acts as a warning that the time for blood will come.

How did America as a new nation develop its economy and place in the world?

The United States, as a new country, took steps to develop its economy and to develop its place in the world. The United States had a diversified economy. The South tended to do farming while the North tended to have industries. We needed to develop our economy after we became independent. Alexander Hamilton understood that one way to develop our economy was to pay our debt. He proposed a debt plan that would combine the debts of the state and the federal government. New bonds would be issued, and along with tax revenue, we would be able to pay our debts. The South was against this to some degree, so to encourage southern support, Hamilton agreed with a proposal to move the capital city to Washington, D.C. in return for southern support of the debt plan.


Other steps were taken to develop our economy. Alexander Hamilton proposed creating a national bank. Having a bank would allow the federal government, businesses, and individuals to have a place where they could put their money and where they could get loans. Henry Clay proposed the development of the American System. This would put protective tariffs on foreign-made products that would allow our industries to have a chance to grow and to develop. We also would improve our internal transportation system. This would allow for farmers and for industries to be able to ship products faster and easier.


We also had to take our place in the world. Other countries were trying to test us by pushing us around. Spain and Great Britain were interfering with our trade. These countries were also encouraging Native Americans to attack us. Great Britain would leave the forts in the West. While some people wanted President Washington to go to war over these issues, he knew we weren’t prepared to go to war. He knew this wouldn’t be good for our country. Instead, he chose to discuss these issues with Spain and Great Britain in order to resolve them without going to war. This would prove that we would stand up to countries pushing us around and that we wouldn’t let them get away with these actions. We negotiated Jay’s Treaty with Great Britain and Pinckney’s Treaty with Spain in an attempt to resolve some of the issues we had with these countries. This showed the world that we would stand up for our interests and that we wouldn’t be pushed around by other countries.


The United States took several steps to develop its economy and to take its place in the world.

What points prove that Antonio is the villain in The Merchant of Venice?

Primarily, it is Antonio's treatment of Shylock which provides support for this contention. One can also assert that Antonio is but a symbol of the inherent faults existent in the society he represents. Be that as it may, Antonio displays a number of unacceptably vile characteristics, as Shylock so pertinently points out:



He hates our sacred nation, and he rails,
Even there where merchants most do congregate,
On me, my bargains and my well-won thrift,
Which he calls interest.



There is no real justification for Antonio's hatred of Jews except that they are of a different faith. Furthermore, it is apparent that Antonio makes a point of publicly denouncing Shylock because he lends out money at interest. These actions indicate a profound and unjustifiable prejudice. One would expect better from one who deems himself Christian, for it preaches forgiveness and tolerance, qualities that Antonio does not display towards Shylock at all.


When Shylock later meets Antonio and talks about the loan, Shylock further emphasizes the abuse that Antonio seems eager to dish out:



Signior Antonio, many a time and oft
In the Rialto you have rated me
About my moneys and my usances:
Still have I borne it with a patient shrug,
For sufferance is the badge of all our tribe.
You call me misbeliever, cut-throat dog,
And spit upon my Jewish gaberdine,
And all for use of that which is mine own ...

... Shall I bend low and in a bondman's key,
With bated breath and whispering humbleness, Say this;
'Fair sir, you spit on me on Wednesday last;
You spurn'd me such a day; another time
You call'd me dog; and for these courtesies
I'll lend you thus much moneys'?



Antonio's actions make it obvious that he despises Shylock. It is ironic that he now approaches the one he deems his enemy, for financial help. This somehow smacks of hypocrisy, for if Antonio is so much against usury, which he deems a pernicious sin, why would he consciously and willfully support one who practices it? He could have asked one of his wealthy Christian friends to extend Bassanio the loan with him as guarantor. He surely must have realized, beforehand, that Shylock would charge him interest? The fact that Shylock is prepared to dismiss the interest later, cannot be used as an excuse.


Furthermore, after Shylock has been found guilty of attempting to bring harm to a citizen of Venice, it is Antonio who beseeches the court to mete out probably the harshest punishment Shylock could ever face. He asks the court to demand that Shylock, who is a deeply devout Jew, change his religion and become a Christian. 


Antonio's request represents his bitterness and resentment towards Shylock and it is obvious that he wishes to hurt and humiliate him in the harshest possible manner. His request is spiteful and vindictive. In fact, he agreed to the terms of Shylock's loan, knowing full well that Shylock probably had an ulterior motive. He signed the agreement against Bassanio's advice and his better judgment.


Although Shylock himself is presented as materialistic, resentful, bitter and vengeful, one can only assume that the last three qualities of his skewed nature were in retaliation and defense to Antonio's intense loathing.

In "Master Harold". . . and the boys, what condition are Hally's clothes in according to the stage notes describing his entrance? What does this...

In "Master Harold". . .and the boys, Hally's clothes are wrinkled and he looks unkempt when he enters the scene. Hally is seventeen, so one assumes that he should be able to look after his own personal hygiene, but Hally is in a low mental state and is not concerned with his appearance. His parents are distant in his life with his mother consumed by his father's physical ailment and his alcoholism. So Hally's parents are not around to look after their son's well-being. Hally's home life is not stable, and we later learn that—at least from Hally's perspective—his mother is not emotionally strong enough to stand up to his father and that when his father is home there is much discord. Hally's unkempt appearance is a symbol of his cry for help and support.

What is the difficulty/ dilemma that Winston faces in the book, 1984?

In 1984, we can sum up Winston's dilemma in the following way: he has become conscious of the party's control over himself and other citizens of Oceania and he wants to overcome it. This dilemma is a driving force in 1984 and we see numerous examples of how it plays out.


In Part one, Chapter One, for instance, Winston buys a diary but instead of writing in it, he spends a long time "gazing stupidly" at the paper. He is terrified of the telescreens in his apartment and of being found out by the party. When he finally plucks up the courage to write, he scribbles frantically all over the paper, as a sort-of cathartic release of his pent-up desire to be free. Over the course of Part One, Winston writes in his diary more frequently, as a symbol of his growing confidence in overcoming the party's control over his thoughts and actions.


In Part Two, it appears that Winston has finally found a solution to his dilemma. Firstly, he begins a relationship with Julia who encourages him to express his rebellious desires in a physical and sexual way. In addition, through conversations with Julia, he articulates memories about his early life, which he had previously repressed. Secondly, in Chapter Eight, Winston and Julia go to O'Brien's apartment where they openly discuss the underground resistance against Big Brother. It seems, then, that Winston has finally found a legitimate way of venting his inward rebellion and that, by becoming a member of the resistance, he will no longer have to demonstrate outward conformity.


But this is not to last. At the end of Part Two, Winston and Julia are arrested by the Thought Police. Imprisoned at the Ministry of Love, Winston expresses his lingering hopes of resistance to O'Brien, a member of the Thought Police. His dilemma has finally been solved but not in the way we expect. Through torture and Room 101, Winston is re-educated and reintegrated into society. He no longer harbours those same feelings of rebellion and independent thought because he now loves Big Brother and has no desire to overthrow him.  

What types of stylistic elements can you identify in Samuel Johnson's prose in The Rambler?

In the Rambler essays, Johnson uses an elevated prose style rather than the conversational, colloquial diction common among many other essayists of the period. This reflects Johnson's interest in setting a high moral tone in these essays, which were designed to impart piety and wisdom.


The style is Neoclassic, emphasizing balanced, rational, and dignified prose modeled on Greek and Roman writers. Johnson wrote of his Rambler essays that he hoped they would “refine our language to grammatical purity, and to clear it from colloquial barbarisms, licentious idioms, and irregular combinations. He wanted the style of each essay to add "to the elegance of its construction, and ... to the harmony of its cadence.”


Johnson often constructed his sentences in a three-part style, as can be illustrated in Essay #134. In this famous essay, Johnson wrote about the pitfalls of procrastination and idleness, subjects with which he was quite familiar. Sentences that show this balanced, three-part form include the following:



There was however some pleasure in reflecting that I, who had only trifled till diligence was necessary, might still congratulate myself upon my superiority to multitudes who have trifled till diligence is vain; who can by no degree of activity or resolution recover the opportunities which have slipped away; and who are condemned by their own carelessness to hopeless calamity and barren sorrow.



The semi-colons separate the three ways Johnson considers himself superior to the multitudes: they have procrastinated too long to make up for it with "diligence" or hard work, they now can't recover their lost opportunities, and they are therefore condemned to calamity and sorrow.


Another example is this sentence:



Thus life is languished away in the gloom of anxiety, and consumed in collecting resolution which the next morning dissipates; in forming purposes which we scarcely hope to keep, and reconciling ourselves to our own cowardice by excuses which, while we admit them, we know to be absurd.



Here it is the participles that divide the sentence into three measured parts: collecting resolution, forming purposes, and reconciling ourselves.


Johnson's sentences might remind of us of carefully balanced neoclassical buildings, where if there are two windows on one side of a door, you can be sure there will be two identical windows on the other side, all in harmony.

Was slavery the primary cause of the Civil War? Explain. In any scenario could the Civil War have been avoided?

Slavery per se was not the primary cause for the Civil War; economic reasons were the primary causes. But, slavery certainly played a large part of the Southern economy.


The development of an agrarian economy in the South that was dependent upon slavery and the expansion of an industrial economy in the North that was based on free labor set up the incompatibility of these economies that led to the conflicts which effected the War Between the States. 


Among these conflicts were sectional conflicts over territories in the West which both sections of the country saw as necessary to their continued development: the North needed more areas for the growth of food as its populations grew; the South desired more land for its agrarian economy. There was also the "foot-race between the competing labor systems"; that is, the creation of new slave or free states. This became a contentious issue, for if the states of one labor system (free vs. slave) became larger in number than the other's, the Congress of the United States could pass laws abolishing the system of labor of the smaller block of states.


The North was becoming more and more unwilling to allow the South to expand slavery as there were many who objected to it on moral grounds and others who did not want the West to become slave states for political reasons. Added to this issue, there was the issue of tariffs. Because the North wanted their industries to prosper, it imposed tariffs on products coming into the country. Since the South needed many of the products made by industries of the North or other places, it had to pay tariffs. Therefore, the South tried to stop tariff increases. 


Compromise with the South became less and less likely with the North because of the moral, political and economic issues of slavery and the economic issue of tariffs. In 1854 this Northern opposition led to the formation of the Republican Party, which then supported the interests of the North [Encyclopedia. com]. When Abraham Lincoln was a candidate for president, he supported entirely the economic interests of the North; so, when he became president, the South felt it had no choice but to secede from the Union if it wished to preserve its economic system, a system that included slave labor.


While there are a number of viewpoints on the Civil War, one viewpoint is that this war could have been avoided if Lincoln had allowed to South to secede, an act which was constitutional according to Jeffersonian democracy:



This was a right that continued throughout the initial drafts of the Articles of Confederation, the Constitution and the Declaration of Independence.



But, instead, President Lincoln ordered the military blockade of the ports that belonged to the South, which was actually an act of war.

What is the cultural significance of "The Tell-Tale Heart" by Edgar Allan Poe?

"The Tell-Tale Heart" by Edgar Allan Poe is not a story of cultural critique. Instead, it is primarily a story of psychological suspense, showing its unreliable narrator's descent into madness. There are a few cultural phenomena we can deduce from the story, but they are not central elements of the narrative.


First, the story is set in a rooming house, which tells us something of the way that unmarried people of moderate incomes lived in this period. Both the narrator and the old man are relatively isolated and living alone, suggesting we are seeing a phase in the modern breakdown of the extended family; in antiquity or the middle ages, these men would have lived in a more communal environment, either on an estate where they worked or with their families.


Next, we can see this is a society that stigmatizes mental illness and has little in the way of public support for mental health. The narrator's insistence that he is not mad conveys a sense that he considers it almost worse to be thought insane than to be thought a murderer.

What are the differences between Thomas Hobbes' and John Locke's concerns with the conditions of the state of nature?

On the whole, John Locke had a far more optimistic view of nature than Thomas Hobbes. Locke believed that every child comes into the world with a blank slate, or tabula rasa. In other words, we come into the world without any pre-existing mental content, and our knowledge and personalities form based on our experiences. This assumption became the basis for John Locke’s theory of knowledge, in which he theorizes, in the tradition of Aristotle, that knowledge comes as a result of interaction and experience with the outside world, as opposed to introspection.


In contrast, Thomas Hobbes believed that humans come into the world with an inborn animalistic nature that predisposes us towards selfishness. According to Hobbes, the state of nature is “solitary, poor, nasty, brutish and short.” It is only through establishing a social order that humans can overcome this rather miserable state of affairs. By abdicating some of their power to social authority, humans gain freedom through protection to live their lives without the self-interested interference of others. This arrangement is often called a social contract.

What is the name of bacteria that catalyze acid mine drainage?

Acid mine drainage or AMD are commonly associated with coal mines and are a result of sulfuric acid, produced from catalysis of sulfur containing minerals. Pyrite, FeS2, is the most common such mineral and is biologically catalyzed by bacteria. In the first step, ferrous (`Fe^(2+)`) ion is generated (from pyrite), which is oxidized to ferric ion (`Fe^(3+)`) by Thiobacillus ferrooxidans, a bacterium.The ferric ion, thus produced, catalyzes the oxidation of pyrite and speeds up the formation of sulfate ion (which forms sulfuric acid). And thus, we end up with acid mine drainage. A number of other bacteria, such as, Leptospirillum ferriphilum and Acidithiobacillus caldus, are also associated with acid mine drainage formation.


AMD is a major environmental concern in regions containing coal mines and extensive research has been conducted to treat it.


Hope this helps.

What is the target of Swift's satire "A Modest Proposal"? How successful is his attack?

The main focus of Swift's satire is the British, as by the beginning of the 18th century, Britons owned 90% of the land in Ireland and soon passed legislation that actually limited the rights of the Irish in their own country.  High rents charged by wealthy British landowners meant rising poverty rates and starvation among Irish farmers, and so Swift skewers the English landowners willing to figuratively "devour" the Irish by suggesting that they might view a proposition in which they literally devour the Irish acceptable, even beneficial in many ways (not the least of which was the plan's ability to lessen the number of "Papists" or Catholics: a major benefit in the eyes of the Protestant English).  Swift writes, "I grant this food will be somewhat dear, and therefore very proper for landlords, who, as they have already devoured most of the parents, seem to have the best title to the children," and he insists that he could "name a country which would be glad to eat up our whole nation."


Swift also attacks (to a much lesser degree) Americans by relating a story whereby he learned from a "very knowing American of [his] acquaintance in London, that a young healthy child well nursed, is, at a year old, a most delicious and nourishing and wholesome food [...]."  In other words, Swift illuminates the view that Americans are as bad as the English in many ways.  


Finally, Swift also satirizes the Irish themselves, as many of them tacitly accepted British rule and refused to take action against the landowners.  His assertions about their willingness to profit by selling their children to be eaten, their skin turned into boots and ladies' gloves, shows their complacency with British rule in quite a negative light.  For if the parents, in the above quote, are willing to allow themselves to be figuratively "devoured," what would prevent them from allowed their children to be literally so?

Discuss the mood in Part One and Part Two of 1984 by George Orwell.

In Part One of 1984, the mood is sombre and oppressive. In the opening paragraphs, we learn of Winston's dilapidated and run-down accommodation block, Victory Mansions, which is pervaded by the smell of "boiled cabbage." We also learn the famous party phrase "Big Brother Is Watching You," and find Winston overcome with guilt about writing in his diary. 


Part One also introduces us to the presence of telescreens, through which the Thought Police monitor every movement of Oceania's citizens, and of the ongoing war with Eurasia. In Chapter Four, we learn about Winston's job at the Ministry of Truth, where the party rewrites history, and of the rationing of food and the shortage of basic items like shoelaces and razor blades.


In stark contrast is Part Two of 1984. Here, the mood is hopeful and optimistic: Winston meets and falls in love with Julia, and they spend an intimate afternoon in the woods in Chapter Two. They begin to spend time together in secret, and Winston rents a room above Mr Charrington's shop for this purpose. Later, in Chapter Eight, Winston and Julia go to O'Brien's apartment and learn about the underground resistance movement. He also receives a copy of Goldstein's book, which further encourages his rebellious feelings against the party. 


But this optimism does not last. Part Two closes with Winston and Julia's arrest by the Thought Police and the realisation that O'Brien is really an inner party member who tricked them into believing in the resistance. The scene is now set for their torture and imprisonment in the Ministry of Love.

What are the similarities and differences in Viola's and Olivia's circumstances in Shakespeare's Twelfth Night?

Shakespeare's Twelfth Night is a romantic comedy concerning the loves and adventures of two pairs of lovers, Sebastian and Olivia and Orsino and Viola. All of the protagonists are members of the upper classes and all are initially thwarted or misguided in their romantic endeavors, but eventually, after many plot twists, mistaken identities, and other entertaining episodes, both pairs of lovers end up happily marrying the right people.


Viola and Olivia are similar in that they are young, attractive women of the upper classes who appear to have recently suffered the loss of their brothers. Both are in love with people who seem unlikely to requite their love due to issues of gender. Both are concerned with the inner nature of their suitors rather than just wealth and power. 


The main difference is that Olivia is portrayed as living at home, enjoying wealth and position under her own identity, while Viola has been shipwrecked and is disguised as a boy and employed as a page. Olivia's brother is actually dead, but Sebastian, Viola's twin brother, lives, and is frequently mistaken for Viola. Viola is in love with Orsino, but Orsino does not know she is a woman. It is only when her true identity is revealed that Viola can move from the position of page to wife, as Orsino sums up in the following passage:



Your master quits you; and for your service done him,


So much against the mettle of your sex, ...


And since you call'd me master for so long,


Here is my hand: you shall from this time be


Your master's mistress.



Olivia's attraction to Viola as a man is resolved when she ends up marrying Sebastian, Viola's male twin, and thus the true version of what Viola was merely pretending to be.

How does the destiny of the tragic hero Okonkwo from Things Fall Apart echo the destiny of the tribal Igbo in Nigeria?

In many ways, Chinua Achebe treats Okonkwo as a representative of the traditional values and beliefs of the Igbo people in Nigeria. Therefore, his tragic fate is symbolic of the fall of Igbo customs and values in the face of European colonialism. Okonkwo is presented as a violent man who perfectly embodies all of the traits that are deemed valuable in the tribal community in Umuofia:



“Okonkwo was clearly cut out for great things. He was still young but he had won fame as the greatest wrestler in the nine villages. He was a wealthy farmer and had two barns full of yams, and had just married his third wife. To crown it all he had taken two titles and had shown incredible prowess in two inter-tribal wars. And so although Okonkwo was still young, he was already one of the greatest men of his time” (8).



The fact that he is described as one of the greatest men in the region renders him a symbol of traditional Igbo beliefs. Thus, Achebe shows how Okonkwo's inflexible attitude is impractical in the face of such drastic changes to Umuofia. Okonkwo is unwilling to alter his ways, and he eventually takes his own life because he is unable to adjust to a Nigeria forever changed by European influence. Obierika blames the District Commissioner and others like him for Okonkwo’s death:



“That man was one of the greatest men in Umuofia. You drove him to kill himself; and now he will be buried like a dog” (208).



Okonkwo’s fate is intertwined with the traditional values of the Igbo in Nigeria, and Achebe symbolically illustrates the death of strictly traditional Igbo culture through the tragic death of Okonkwo.

What is the easiest way to make money from the stock market?

The fluctuations of the stock market are largely unpredictable. Indeed, there is a theory called the efficient market hypothesis which says that they are completely unpredictable, because all publicly-available information about future stock prices is automatically incorporated into the current price by the functioning of the market.


Personally I consider the efficient market hypothesis far too strong. Human beings are not completely rational, and we often engage in behaviors like following the herd or being overconfident that can lead to systematic distortions in the prices of stocks and other assets. Thus, stock prices are not completely incorporating all available information, and it is possible for investors with very detailed knowledge and sophisticated forecasting methods to predict the stock market at least with accuracy better than chance. (An example of someone doing this successfully is Warren Buffett, who has averaged an annual return over 20% for decades while most people get about 5% and the market as a whole gets 7%.)

You, however, are unlikely to have access to the kind of detailed information and complex forecasting models that someone like Warren Buffett has. Thus, you should probably treat the stock market as a random system, which obeys a fat-tailed distribution, meaning that it sometimes doesn't change at all and other times swings wildly in all directions for no apparent reason.

You could therefore place risky bets on this system, hoping to get lucky, and that would indeed be the easiest way to make money on the stock market, and you could in fact win big and become a millionaire overnight--but it is also extremely risky, and you are just as likely to lose as you are to gain.

The safer bet is to diversify, and try to invest in as broad a portfolio as you can. Rather than choosing individual stocks, you are better off buying broad exchange-traded funds, or ETFs, that invest in a wide variety of stocks simultaneously. By buying ETFs that follow the Dow Jones Industrial Average or the S&P 500, for example, you can get a return that closely approximates the average return of the stock market as a whole--which as I said is a couple of percentage points higher than what most people get when they try to pick stocks on their own.

Will this make you a millionaire overnight? Absolutely not. But it also won't cause all of your money to suddenly evaporate. A diversified portfolio is the best way to grow your savings while still maintaining a moderate level of risk.

In other words, don't try to be like the people who made 1000% returns; they just got lucky. Don't try to be like the people who make 20% returns; they have access to tools you don't. Just try to make 7% returns; that's the safe bet that will actually pay off.

How can you determine the mass of an element present in a compound if you do not know the identity of the element?

In order to solve this problem, you will also need to know the percent by mass of the other element in the compound. The percent by mass of the other element should be given in your question.


Example: Given the compound, `~XS_2` , determine the mass of element X. The compound is 40.064% S by mass. "X" is the unknown element in the compound.


Step 1: Determine the grams of elements X and S.


Grams of S: Assume that you have a 100 g sample of compound `~XS_2` . Since `~XS_2` is 40.064% S, there would be 40.064 g of S in a 100 g sample.


Grams of X: Grams of X can be calculated by subtracting grams of S from 100 g.


   (100 g `~XS_2` ) - (40.064 g S) = 59.936 g X


Step 2: Determine the moles of the known element S.


In order to convert grams of S to moles, multiply grams of S by the conversion factor, 1 mole S = 32.065 g S. 32.065 g is the atomic mass of S as shown in the periodic table.


   (40.064 g S)(1 mol S/32.065 g S) = 1.2495 mol S


*Notice that the conversion factor is oriented such that the unit "grams" is on the bottom - this enables you to cancel out gram units and be left in units of moles.


Step 3: Set up a mole ratio to determine the moles of unknown element X.


Notice that the ratio of subscripts in the compound `~XS_2` is 1 M:2 S. This means that the ratio of moles of element M to moles of element S in the compound is 1:2. Set up equivalent mole ratios as shown below.


   (? mol X/1) = (1.2495 mol S/2)


Rearrange the equation or "cross-multiply" to solve for unknown moles of X.


   ? mol X = [(1.2495 mol S)(1)]/2 


   ? mol X = 0.62475 mol X


Step 4: Determine the atomic mass of unknown element X by dividing grams of element X (from Step 1) by moles of element X (from Step 3).


   (59.936 g X)/(0.62475 mol X) = 95.936 g/mol 


The element in the periodic table with this mass is molybdenum (Mo). Therefore, the formula of the compound is `~MoS_2`

What does the Communist Manifesto mean by the statement that the bourgeoisie has forged the weapons that will be used against it?

Marx means that the bourgeoisie, the owners of the means of production, have created a weapon by exploiting the proletariat, who are the masses of people who work for a living. The owners have paid the workers low wages and forced them to endure poor working conditions. The bourgeoisie do this so they can collect the profit the proletariat's labor produces. The proletariat will become a "weapon" when they rise against their masters. First, since there will always be more people in the proletariat than in the upper classes, the proletariat (often called "the masses") will have numbers on their side. Eventually, Marx argues, these people will be politicized and recognize they "have nothing to lose but their chains," as he says later in this work. Once the workers recognize that their labor creates all the wealth in society and that they greatly outnumber their masters, they will rise up in revolution against the bourgeoisie and take over the means of production for their own benefit.

Provide a character sketch of the ghost from "The Canterville Ghost."

Sir Simon, also known as the ghost, is one of the main characters in the story, "The Canterville Ghost." One of the strongest impressions of Sir Simon is that he has criminal tendencies. When he was alive, for example, he murdered his wife, Lady Eleanore, in the library of Canterville Chase because she was "very plain" in appearance and not a good housekeeper. 


In addition, Sir Simon is very proud of his earthly achievements. This is supported by his affections towards the suit of armour. He proudly recalls how he wore this at a tournament in Kenilworth and that Queen Elizabeth I, the Virgin Queen, had complimented it. This feeling of pride also extends to his achievements in the afterlife. He is gleeful, for example, when he recalls some of the people he has frightened at Canterville Chase. He appeared to the Dowager Duchess, for instance, by placing his skeleton hands on her shoulders as she dressed for dinner. She was so terrified that she fell into a "fit" for some weeks after. Similarly, Madame de Tremouillac was "confined to her bed for six weeks" after Sir Simon appeared to her as a skeleton while reading her diary by the fire. 


But Sir Simon exhibits vulnerabilities, too. He is easily hurt and humiliated by the Otis family, for example, when his attempts at scaring them completely fail. The twins fire their pea-shooters at him, Mrs Otis offers him a tincture for his throat and Washington hems him in with a "garden syringe." Despite donning his most infamous and scary costumes, he cannot make them frightened of him and this causes him to experience a deep depression. 


But this depression leads to the story's climax because it forces Sir Simon to confront his bad deeds and seek redemption in the Garden of Death. To do this, he successfully appeals to Virginia Otis who follows him through the wall of the Tapestry Chamber. There, she sheds tears for Sir Simon and he is granted the gift of eternal rest. 

Given that the area of a forest on the map is 6 cm^2, calculate the actual area of the forest in square kilometers. The scale of the map is 1 cm...

This question can be answered by setting up a proportion. But first, we need to understand how to convert the area of the region on the map to the area of the land this region represents.


If the scale of the map is 1 cm : 2.5 km, this means that 1 cm on the map corresponds to the 2.5 km of the actual land. The square on the map that has a side of 1 cm has the area of `1 cm * 1 cm` , or 1 square cm. Then, this square of the map corresponds to the piece of the actual land that has the area of


`2.5 km * 2.5 km = 6.25` square km.


Therefore the proportion we need to answer the question is


1 square cm corresponds to 6.25 square km


6 sq. cm (area of the forest on the map) corresponds to unknown area of the actual forest, x sq. km.


This can be written as the equality of two ratios:


`1/6.25 = 6/x`


Alternatively, it can also be written as `1/6 = 6.25/x` .


In any case, the proportion can be solved by cross-multiplying:


1*x = 6*6.25


x = 37.5 square km.


The actual area of the forest represented by 6 sq. cm region on the map is 37.5 square kilometers.

Do you think that the poem, "The Eagle," is only about a bird?

No, the poem isn't just about a bird; we can also interpret it as a comment on absolute power and the effects of such power on humans.  Personifying the eagle as having "crooked hands," gives us a clue that the eagle might be symbolic of a person, since people have hands.  Further, there are two definitions for crooked: bent (like an eagle's talons would be) and corrupt (as someone who holds absolute power likely is).   Perhaps this supreme ruler holds onto his power through corruption.   


Moreover, the eagle is "close to the sun," implying that his power is, indeed, absolute; he is the highest authority perhaps because he is the only authority.  The fact that the sea beneath him is described as "crawl[ing]" aids this interpretation because crawling is an action associated with someone who is powerless, subjected to the demands of a supreme authority.  Consider how we describe insects as crawling (when it might be more correct to say that they there are walking or scooting), and insects are typically at the mercy of larger predators because those predators are stronger than the insects.  To the eagle -- or the supreme ruler, those "beneath him" -- either literally or figuratively -- are as insignificant and unimpressive as bugs.  


Finally, when the narrator says that the eagle watches from his mountain walls, it is notable that mountains are natural, like the eagle, but walls are manufactured.  Thus, we might interpret the line as an eagle standing atop his crag, or a supreme leader ruling from his fortress, an edifice that protects him by keeping others out.  In the end, the eagle "falls" like a "thunderbolt": we could read this as an eagle diving for prey, quickly and destructively, or we could interpret it as the way a supreme leader tends to lose power -- all at once and violently.  When a supreme leader falls, it is usually the result of war or a coup, and so on.

The ocular of a microscope is also known as the eyepiece and is the place where we position our eye/eyes (depending on whether we have a monocular or binocular system) to look at the sample. In comparison, the objective lens is close to the sample. Each of the two, the ocular and the objective, has a certain magnifying capacity. The total magnification of the microscope is the product of these two magnification. 


In this case, both the ocular and the objective have a magnification of 10x each. Hence the total magnification of the microscope is


total magnification = magnification of ocular x magnification of objective 


= 10 x 10 = 100x


Thus, the total magnification of the microscope is 100x. In other words, the microscope is capable of magnifying details by a factor of 100.


Hope this helps.

If we use weedicides, why are useful crops not affected?

Weedicides, which are also known as herbicides, are chemicals which are harmful to plants. Herbicides can be selective (only kill certain types of plants) or non-selective (kill all types of plants).


Selective herbicides have different mechanisms of action. Different plants will have varying degrees of susceptibility to different mechanisms of action due to differences in absorption of the chemical and the physiology or morphology of the plant. Thus, care is taken to select the appropriate herbicide to eliminate the specific type of weed present.


With respect to non-selective herbicides, it is generally the manner in which these herbicides are applied which limits the effects on useful crops. Non-selective herbicides are generally dispensed as a liquid spray which is applied directly onto the weeds. Care is taken to prevent applying the herbicides to the useful crop plants. Alternatively, these types of herbicides may be applied to entire fields before the useful crop is planted.

The periodic table is arranged from left to right by ______?

The periodic table is arrange in order of increasing atomic number. The horizontal rows are called periods and the vertical columns are called groups. As you move from left to right across a group each element has one more proton and one more electron than the one before it. The number of valence (outer) electrons that an atom has determines its chemical properties, so there are several left-to-right trends that result from the succesive change in the number of electrons. These patterns start over and repeat aftert the noble gases (group 8A), which is why a new row starts after each noble gas. 


1. The ionization energy increases from left to right within a period. This is the energy required to remove an electron. The metals, which are on the left side of the periodic table, lose electrons easily and form positive ions. The non-metals, on the right, tend to gain rather than lose electrons because of their high ionization energies.


2. The electronegativity, which is the attraction for shared electrons in a covalent bond, increases from left to right within a period.


3. The atomic radius decreases from left to right within a period. As each additional proton is added the outer electrons are more attracted and move in closer. 


The repeating or periodic nature of these properties results in element in the same group having similar chemical properties.


If you compare the periodic table to a calendar, the days of the week would be considered a periodic property. They repeat every 7 days, and a month is arranged into weeks 7 days in length such that all days in the first column are Sundays, all days in the second column are Mondays, and so forth.

What happens in the poem "Alabanza" by Martin Espada? What evidence can I use to describe it?

Alabanza is a celebration of the lives of 43 members of Hotel Employees and Restaurant Employees Local l00, a union that included staff who worked at the Windows on the World restaurant. All 43 employees were killed in the terrorist attacks of September 11, 2001.

“Alabanza” is the Spanish word for praise. In his poem, Martin Espada memorializes different members of the kitchen and waitstaff, describing at different times their physical appearances, home cultures (see example 1), and their labor, as well as the fragile beauty of the human experience (see example 2).

Example 1:

“Praise the cook with a shaven head  
and a tattoo on his shoulder that said Oye,  
a blue-eyed Puerto Rican with people from Fajardo,  
the harbor of pirates centuries ago.  
Praise the lighthouse in Fajardo, candle  
glimmering white to worship the dark saint of the sea.  
Alabanza. Praise the cook’s yellow Pirates cap  
worn in the name of Roberto Clemente, his plane  
that flamed into the ocean loaded with cans for Nicaragua,  
for all the mouths chewing the ash of earthquakes.  
Alabanza. Praise the kitchen radio, dial clicked  
even before the dial on the oven, so that music and Spanish  
rose before bread. Praise the bread. Alabanza.”

The picture that Espada paints of this “blue-eyed Puerto Rican” with his “shaven head and a tattoo…that said Oye,” just one such description in the poem (see the waitress, busboy, dishwasher), is wonderfully vivid, and successfully brings the reader into the lives of these doomed people. It renders them real to us, and makes us feel both their fragility as well as our own.

Example 2:

“Praise the kitchen in the morning,  
where the gas burned blue on every stove  
and exhaust fans fired their diminutive propellers,  
hands cracked eggs with quick thumbs  
or sliced open cartons to build an altar of cans.”  

The primary theme of the poem is praise. Espada repeats the word, in both Spanish and English throughout the poem, detailing the lives of the dead workers, and what makes his celebration of them particularly beautiful are the tiny details he highlights, allowing readers to grasp the commonalities that all humans share.

Example 3:    

Alabanza. Praise the dish-dog, the dishwasher  
who worked that morning because another dishwasher  
could not stop coughing, or because he needed overtime  
to pile the sacks of rice and beans for a family  
floating away on some Caribbean island plagued by frogs.  
Alabanza. Praise the waitress who heard the radio in the kitchen
and sang to herself about a man gone. Alabanza.”  

The poem’s final two stanzas concern the terror of the attack itself (see example 4), as well as the transcendence of the human soul (see example 5). The final stanzas also address the human cost of the attacks and the military response to them.

Example 4:

“…thunder wilder than thunder,  
after the shudder deep in the glass of the great windows,  
after the radio stopped singing like a tree full of terrified frogs,  
after night burst the dam of day and flooded the kitchen,  
for a time the stoves glowed in darkness like the lighthouse in Fajardo,
like a cook’s soul.”

“Thunder wilder than thunder” refers to the cataclysmic boom of the airliners hitting the towers; “shudder deep in the glass of the great windows” refers to the actual shaking of the building after the impact and as the building began to collapse.

Example 5:

“Soul I say, even if the dead cannot tell us  
about the bristles of God’s beard because God has no face,  
soul I say, to name the smoke-beings flung in constellations  
across the night sky of this city and cities to come.  
Alabanza I say, even if God has no face.  

Alabanza. When the war began, from Manhattan and Kabul  
two constellations of smoke rose and drifted to each other,  
mingling in icy air, and one said with an Afghan tongue:  
Teach me to dance. We have no music here.
And the other said with a Spanish tongue:  
I will teach you. Music is all we have.

In the final stanza, Espada also imagines the smoke that emanated from the sites of the terrorist attacks (Manhattan) and military response (Kabul) intermingling with one another after the destruction and suffering. The image is beautiful and poignant, with the Afghan smoke asking the Spanish smoke (note that the American smoke “speaks” Spanish, the language of the deceased restaurant employees) to teach it to dance. The Spanish smoke agrees, “I will teach you, Music is all we have.”

The oxidation of iodide ion by peroxydisulfate ion is described by the equation: 3 I− (aq) + S2O82− (aq)  I3− (aq) + 2 SO42− (aq). If...

The relative rates of change in concentration of reactants is stoichiometric, meaning it's related to their coefficients. For the equation,


`3 I^-_(aq) + S_2O_8^(2-)_(aq) -> I_3^-_(aq) + 2 SO_4^(2-)_(aq)`


The rates of change in concentration of the two reactants are related as follows


`- 1/3 (Delta[I^-])/(Delta t) =-(Delta[S_2O_8^(2-)])/(Delta t)` 


This is true because, in the same time period, three times as much I- is consumed as S2O8(2-). This makes the rate of S2O8(2-) equal to one third the rate of I- consumption. 


The rate of change in concentration of S2O8(2-) is therefore equal to


1/3 (-6.0x10^(-3) mol/dm-s) = -2.0 x 10^(-3) mol/dm-s


The rates have negative values because the concentrations are decreasing. The rates of change in concentration of the products are positive and are also related according to the coefficients, for example 


`-1/3 (Delta[I-])/(Delta t) = + (Delta[I_3^-])/(Delta t)`

Who is Ariana Grande?

Ariana Grande is a currently twenty-two year-old (her birthday is June 26th, 1993) American singer of Italian descent who decided to seriously pursue a musical career at age thirteen. Grande made her Broadway debut in 2008 with a supporting role in 13 (a musical by Jason Robert Brown, Dan Elish, and Robert Horn) as Charlotte, a cheerleader. This platform launched her into an audition for Victorious, a television show on Nickelodeon; Grande landed the role of Cat Valentine, and the show went on to shape Grande into a "teen idol."


During this time, Grande continued her vocal training under the tutelage of Eric Vetro and recorded many covers. After three years of hard work, her first album, Yours Truly, was released in August of 2013, debuting as Number One on the US Billboard 200 chart. She has since gone on to release two more albums: My Everything (2014) and Dangerous Woman (2016). 


Grande lists Madonna, Gloria Estefan, Whitney Houston, Brandy Norwood, Amy Winehouse, and many other powerful female artists as influential in the development of her work.


Although she has largely maintained her "good girl" image, Grande was placed under a great deal of scrutiny after being caught licking doughnuts in a shop and commenting on how much she hates America in 2015. This extremely odd behavior was initially chalked up as commentary on the prevalence of obesity in America. Grande later apologized, and the scandal has since died down. 

How would you describe Macbeth's demeanor as he converses with Lennox and Macduff?

At the end of Act II, Scene 2, Lady Macbeth tells her husband:



Hark, more knocking.
Get on your nightgown, lest occasion call us
And show us to be watchers. Be not lost
So poorly in your thoughts.



When Macbeth appears in Act II, Scene 3, he is wearing a nightgown and is "lost in his thoughts." He is almost like a sleepwalker. The only reason he has put in an appearance is that no one was responding to the persistent knocking, and he finally felt compelled to go down and see what was going on. By the time he arrives at the gate, the Porter has just admitted Macduff and Lennox. Macduff says:



Our knocking hath awaked him: here he comes.



Macbeth has not slept that night. His strange, withdrawn behavior gives Macduff the false impression that Macbeth is angry because the knocking woke him up. Macduff offers a veiled apology:



He [King Duncan] did command me to call timely on him;
I have almost slipped the hour.



Macbeth simply replies,



I'll bring you to him.



Macbeth is not being deliberately rude; he just can't think of the customary polite things to say because he is thinking of his horrible deed and dreading the discovery of Duncan's body. Macduff is angered by Macbeth's reply. Macduff's own response is laden with irony.



I know this is a joyful trouble to you;
But yet 'tis one.



Macbeth doesn't get any of the innuendo. He is totally lost in his own thoughts, just as Lady Macbeth observed when she told him:



Be not lost
So poorly in your thoughts.



Macduff will remember Macbeth's strange behavior later on and will realize it was not caused by being disgruntled over a simple thing like being wakened by the knocking. Macbeth is consumed with guilt, remorse, shame, regret, fear, horror, and many other conflicting emotions. He will continue to behave like a sleepwalker until Macduff emerges from the King's chamber crying:



O horror, horror, horror—
Tongue nor heart cannot conceive nor name thee!



Macbeth had planned to be in bed with his wife when the King's body was discovered, both husband and wife pretending to be sound asleep. Shakespeare wanted Macbeth to be present when the murdered body was discovered. This would make that scene all the more dramatic. Shakespeare invented the knocking, which forced Macbeth to stop pretending to be asleep and make an appearance. Once he encountered Macduff and Lennox, Macbeth was forced to lead them to the very door behind which lay a scene he could not dare to imagine. Earlier, he told his wife:



I am afraid to think what I have done;
Look on't again I dare not (Act II, Scene 2).



Macbeth's demeanor during the entire time he converses with Macduff and Lennox can be described as strange, withdrawn, stiff, and even trancelike. Whereas the two innocent arrivals interpret it as cold, surly, discourteous, abrupt, and angry because they have been pounding on his gate for so long that they woke him up out of a sound sleep. The audience understands the truth which Macduff and Lennox do not. Macbeth has to act like a host as best he can, and he knows he is going to have to put on an even harder act when the body is discovered. In trying to conceal his true feelings, he is creating a false impression. Macduff and Lennox are so innocent that they think Macbeth is simply angry because they woke him up. In reality, Macbeth hasn't even been to sleep. He has even been warned by a mysterious voice that he might never sleep again. As he tells his wife earlier in some of Shakespeare's most beautiful language:



Me thought I heard a voice cry “Sleep no more!
Macbeth doth Murder sleep”—the innocent sleep,
Sleep that knits up the ravell'd sleave of care,
The death of each day's life, sore labor's bath,
Balm of hurt minds, great nature's second course,
Chief nourisher in life's feast—


Still it cried, “Sleep no more!” to all the house;
“Glamis hath murdered sleep, and therefore Cawdor
Shall sleep no more. Macbeth shall sleep no more” (Act II, Scene 2).


`a_1 = 2, r = pi` Write the first five terms of the geometric sequence.

The first five terms of geometric sequence can be computed with formula, such that:


`a_n = a_(n-1)*q`


`a_2 = a_1*q => a_2 = 2*pi`


`a_3 = a_2*q => a_3 =2pi*pi = 2pi^2`


`a_4 = a_3*q => a_4 =2pi^2*pi = 2pi^3`


`a_5 = a_4*q => a_5 =2pi^3*pi = 2pi^4`


Hence, evaluating the five terms of geometric sequence yields `a_1 =2, a_2 = 2pi, a_3 =2pi^2, a_4 =2pi^3, a_5 =2pi^4.`
