Faber says, "Remember, the firemen are rarely necessary. The public itself stopped reading of its own accord." What does he mean?

Faber means that the job of the firemen, to destroy books when they are found, is becoming less and less necessary because not many people read books anymore.  The society in the story has become so busy in other, less educational pursuits, that even if there were books around, they probably wouldn't read.  Therefore, there aren't many books that need to be destroyed as fewer and fewer people bother to read.  This was one of the strong messages Bradbury was trying to send with the story; that if people become obsessed with self-indulgent activities, become concerned with political correctness to the point of blandness, become more concerned with entertainment than with enlightenment, then books will naturally become obsolete. He was warning the reader to avoid allowing this to happen.

Who or what is the main factor that caused Romeo and Juliet to die? eg. the hatred between the two families or a person's actions or intentions?

The answer to your question can be found in the Prologue.

"Chor. Two households, both alike in dignity,

In fair Verona, where we lay our scene,

From ancient grudge break to new mutiny,

Where civil blood makes civil hands unclean.

From forth the fatal loins of these two foes

A pair of star-cross'd lovers take their life;

Whose misadventure piteous overthrows

Do with their death bury their parents' strife.

The fearful passage of their death-mark'd love,

And the continuance of their parents' rage,

Which, but their children's end, nought could

remove,

Is now the two hours' traffick of our stage;

The which if you with patient ears attend,

What here shall miss, our toil shall strive to

mend."

The Prologue tells us that Romeo and Juliet will fall in love and then die.  Their destiny is fated, or dictated by the long standing feud between their two households.  Technically, the feud is responsible for the structure that results in their deaths, but their individual actions also contribute to their deaths.

But consider, if the feud, which I believe is the main factor, did not exist, then Romeo and Juliet would not have had to hide their love or their marriage.

Write a character sketch of Madame and Mister Loisel.

Madame Loisel feels that she was born for luxury.  She is a beautiful woman and believes that she should be living an aristocratic life, draped in fine clothes, jewels and furs.  She imagines herself to be living a life opposite of what her true destiny is, a life of meagerness.

It is because of Madame Loisel's deeply held belief that life has cheated her out of her due, that results in her reaction to the invitation to the fancy party.  The party, Madame Loisel feels is where she should be, therefore, she must look the part.  Madame Loisel is a Cinderella in reverse.  She gets to go to the ball, and instead of losing a glass slipper, she loses her friend's necklace.

Her life is then turned into an existence of hardship and hard labor. She ends up in rags.

Monsieur Loisel is a hard-working man who loves his wife, but does not understand her.  He wants to please her, and makes sacrifices to give her the luxury, if only temporarily, that she so craves.  He is a simple man who is satisfied with his social standing in life.  He has no aspirations to be among the aristocrats like his wife.  He is content with his simple life.

Both these characters share some reponsibility for the hard work they endure to buy a new necklace.  Individually, and together, they do not trust the rich, Madame Loisel, out of envy and jealousy, and Monsieur out of a sense of fear.  He is afraid of the power of the rich 

Differences between financial/managerial accounting. Give example of the type of problems and issues exmined by each of these areas of...

Accounting refers to the function of recording and
analysing the operations and conditions of an organization in primarily monetary terms.
The information generated by accounts is used by different sets of people in many
different ways. Depending on the primary purpose served by the accounting function, it
is classified in different sub functions. Financial accounting and managerial accounting
are two such sub-function within accounting.

Financial
accounting is concerned with information on a firm that is required and used by people
not involved in management of the company. It includes people such as shareholders and
other investors, regulatory and other government authorities, financial institutions,
suppliers, customers, and community in general. They use this information to know the
state of the company including things like its profitability and financial worth. The
information may also be used to ascertain and ensure that company a is being managed by
appointed managers honestly, conforming to all legal requirements and good ethical
standards. Financial accounting generally produces information according to methods and
formats specified by statutory authorities. Also such information is usually audited and
certified by independent professional auditors. The most common example of the financial
reports is the annual reports published by companies which contain among others, the
audited and certified annual accounts of the company along with an auditor's report and
a director's report.

Managerial accounting is concerned
with generating information and analysis designed to help manager of an organization to
manage ti efficiently and effectively. While managerial accounting also uses the basic
accounting statement used for financial accounting. these statements are generally more
detailed and more frequents. Also managers use additional information and analysis such
as comparisons with budgets and targets, standard costing, variance analusis and ration
analysis. Managers use this information to monitor, control and plan the activities of
the functions they manage.

In "The Guest," are the characters of (Daru, the Arab, Balducci) flat, round, dynamic, or static?

I'll define these terms for you and then let you decide which category each of the characters you've named fits into.

A round character is usually the main character or one of the main characters in a story. These characters are fully developed in all aspects: physical, mental, emotional. So they seem to be real people who look, think, and behave the way a real person might (even if the situation might seem unreal, as in science fiction or fantasy). An example of a round character is Huck Finn. You can imagine any teenage boy rafting down the Mississippi.

A flat character is not very developed at all. These are the stereotypes: the villain, the shyster, the knight in shining armor. The author may describe physical appearance in detail but typically doesn't spend much time letting the reader get into the character's head. They are predicable in thought and action. For example, most characters in fairy tales are flat.

A dynamic character experiences some sort of change over the course of the story. That change might be a new understanding or a change of heart or a change in values or commitment. That doesn't include change in physical appearance or circumstance. An example of a dynamic character would be Ebenezer Scrooge, who changes from a miser into a generous person.

A static character remains the same from beginning to end and undergoes no change.

Now that you have these definitions and examples, what kind of characters do you think Daru and the Arab are?

How does Iago's treachery finally work itself out in Act 5 of Othello?

Iago's treachery plays out throughout Othello. We see it working to disrupt relationships, poison attitudes, etc. This comes to a peak in Act V. That's when he tries to kill Cassio, and when he does kill Roderigo. He smears Bianca almost as an afterthought.Acting on Iago's manipulations, Othello kills Desdemona. There's a huge upheaval, and the truth comes out about Iago's lies. Othello tries to kill Iago, but fails. Iago stabs his own wife (cold!), and Othello kills himself in despair over what he's done.

In short, everyone is either dead, has a ruined reputation, or both.  

What “imaginary” case does Jaggers “put before” Pip in Chapter 51 of "Great Expectations"?

Mr. Jaggers asks Pip to imagine that a woman who is being tried for murder has a child she has concealed from the world.  She is obliged in her situation to tell her lawyer about the child, and the lawyer, coincidentally, knows a rich old lady who is searching for a child to raise as her own.  The lawyer, pragmatic to the point of jadedness by his experiences, can see no better future for the child than that she be given up and put in the care of the old lady with means.  The woman being tried follows the advice of her lawyer concerning the child, which turns out to be a fortuitous decision.  The woman's mind is unhinged by her hardships and when she is acquitted she puts herself under the care of her lawyer; meanwhile, the child grows up and marries, never knowing that her real parents are alive.

The "imaginary" case that Jaggers "puts before" Pip is the true story of Magwitch, Molly, and Estella.  Jaggers presents the case as hypothetical so that he will not have to admit to his part in the situation, even though he and Pip know very well about whom he is talking.  Jaggers puts the case before Pip to emphasize his belief that no one would benefit from the secret being revealed now, and that things are better left alone (Chapter 51).
