In A Raisin in the Sun, Walter makes the decision to move into the house because he believed that his fathers hard work throughout his life had paid for the house that they would live in. The decision to move into the house causes the audience to feel a triumphant aesthetic impact.
A contains an error: "and then she publishes them under a false name" is an independent clause and should have a comma before it.
B contains an error, as the comma should be before "but", not after it, for the same reason as A.
C correctly shows what should have been done in A and B.
D should not have a comma after "but".
C is the correct answer.
Huckleberry Finn has a deeper connection with Jim than with any other character in the novel. This contrast is especially striking given contemporary attitudes on race; though published after the Civil War, it recreates an antebellum Southern society that was completely organized around slavery. Relationships between white and black people were thought to be inevitably antagonistic, a master-slave relationship and not one of equals. Huck, however, does not see Jim as a servant; rather, he feels a kinship with him. Both are outcasts; Jim because he is a black man in a slave society, Huck because of his family situation. His father is abusive and alcoholic who doesn't care for him, and the two women who sometimes care for him try to change his character. Therefore he feels at odds in society, and has trouble fitting in. This makes him more sympathetic to Jim than to other white people.
Bilbo Baggins, the title character in the Hobbit, is the protagonist of the whole story. He lives in an unspecified time that seems to be very ancient (seems like the Victorian era). Hope this helped!
