Answer:
Probably A or B.
Explanation:
"Other countries with such divisions have in fact divided into new nations...but not this one, impossibly interwoven even in its hostilities." The passage does say America is still together despite the decisions, which makes me believe option B is correct. However, A also could be correct because the main idea of the passage largely is the differences between religion, sexuality, and race in America where "What is the point of a nation in which...speak in theory of hatred, one for the other? What is the point of a nation in which one part always seems to be on the verge of fisticuffs with another?"
By giving the setting at the beginning of a story, it gives the reader an idea of what the plot will look like. If the setting of a story is in a haunted mansion on Halloween night, the reader has an idea that the plot will probably involve ghosts, chasing, capture, etc. Basically any Scooby-Doo movie ever. All in all, the setting gives the reader an idea of how the plot will lay out.
