Read the passage from Ronald Reagan's "Tear Down This Wall" speech. Perhaps this gets to the root of the matter, to the most fundamental distinction of all between East and West. The totalitarian world produces backwardness because it does such violence to the spirit, thwarting the human impulse to create, to enjoy, to worship. The totalitarian world finds even symbols of love and of worship an affront. . . . As I looked out a moment ago from the Reichstag, that embodiment of German unity, I noticed words crudely spray-painted upon the wall, perhaps by a young Berliner, "This wall will fall. Beliefs become reality." Yes, across Europe, this wall will fall. For it cannot withstand faith; it cannot withstand truth. The wall cannot withstand freedom. What is Reagan’s main purpose in this passage?

To urge to end communism is the correct answer.

Explanation:

Ronald Reagan was an American president who served from 1967 to 1975. The speech Tear Down This Wall was delivered by him on June 12, 1987, and it was an open invitation to Mikhail Gorbachev to destroy the Berlin Wall, which as a big symbol for the USSR; due to its symbolic importance, it would also mean the end of communism, so by delivering this speech, the then-president urged to end communism.

C) rhetorical question.

Explanation: a rhetorical question is a literary device that consists in asking a question in order to create a dramatic effect or to make a point rather than to get an answer. In the given excerpt from Patrick Henry's famous Virginia Convention speech we can see a clear example or a rhetorical question, he uses a question to make the point that the purpose of the martial array is to force them to submission.
