Read the paragraph.(1) Dr. Martin Luther King Jr. uses repetition to give his speech rhythm and momentum. (2) "Let freedom ring” is a phrase which is used many times in his speech. (3) "Let freedom ring” is a phrase that leads to an exciting conclusion.

Choice D combines the two ideas clearly: the phrase “Let freedom ring” is used many times, and it helps lead to an exciting conclusion. Choice A incorrectly suggests the phrase is repeated because the conclusion is exciting, while C is awkwardly phrased and makes “many times” seem to describe leading to the conclusion rather than using the phrase.
