Question

read the following excerpt from president john f. kennedys \we choose to go to the moon\ speech. then, answer the question that follows.
but why, some say, the moon? why choose this as our goal? and they may well ask why climb the highest mountain? why, 35 years ago, fly the atlantic? we choose to go to the moon.
which rhetorical device does kennedy use to support his argument?
antithesis: he is contrasting mountain climbing and flight
figurative language: he is using personification to explain the newness of the idea of space exploration
irony: he is saying the opposite of what he means about mountain climbing and flight
rhetorical question: he uses a series of questions to make the audience realize the necessity of space travel

Explanation:

The excerpt uses a sequence of questions that do not require a direct answer; instead, they are designed to engage the audience and emphasize the purpose of choosing space exploration as a goal, which fits the definition of rhetorical questions. The other options are incorrect: there is no contrast (antithesis), no opposite meaning (irony), and no personification used here.

Answer:

Rhetorical question: he uses a series of questions to make the audience realize the necessity of space travel
