From the excerpt you posted it looks like the writer's primary purpose is to persuade the audience to share his point of view.
This can be seen in phrases like "it seems to me that the decision is easy", where he implies that he has enough knowledge to see something that the Township officials are not seeing.
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?"
The purpose of Mandela's speech was not simply to address the nation as their new president and give gratitude to those who put him there but instead to make a statement that South Africa was going to make immense changes and unify to show the world what the nation could truly do in order to become a land of hope. There are a few purposes to this speech, one being to unify the nation of south Africa by bringing the blacks and the whites together. The speech was also used to motivate and inspire the people of South Africa. I know this because I've studied Mandela's life in one of my subjects at school.
The audience for this speech was the people of South Africa. He addresses every one he possibly can to broaden his audience so that every South African hears his message.
Nelson Mandela
"I stand here before you not as a prophet but as a humble servant of you, the people."
Mandela repeats the word negotiations as he wants to encourage and push for more negotiations - a thing that will bring them closer to freedom.
