Answer:
"And so let freedom ring from the prodigious hilltops of New Hampshire. Let freedom ring from the mighty mountains of New York. Let freedom ring from the heightening Alleghenies of Pennsylvania."
Step-by-step explanation:
Repetition is the use of the same words or phrases over and over again in a text or speech. This presents an emphasis on the intended meaning and tactic of keeping the listeners focused on the main idea of the whole text or speech.
In Martin Luther King's "I Have a Dream" speech, he uses a lot of repetition. One such instance is the continuous use of the phrase "let freedom ring" as seen in the last part of the given excerpt. This supports Courtney's topic sentence of the use of repetition in King's speech.
