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?"
C. To support the main idea.
Answer:
Don’t look down the entire time the other person is speaking is the correct answer.
Explanation:
Letter A is incorrect because it is a good idea to write down some notes so the person won't forget what he wants to say during his intervention.
C is also incorrect because the person shouldn't write everything, because it means that he should learn how to categorize what the other person says because not everything is important.
D is also incorrect because if Ren did so he would show that he need to improve his listening skills.
B is correct because this way Ren would show that he can both pay attention to the other person while writing. It would also mean that he can see what the other person is doing, since body language could be very important for the debate.
