Question

read this line from martin luther kings \i have a dream\ speech. it is obvious today that america has defaulted on this promissory note.... this line appeals most to the audiences emotion. character. humor. logic.

Explanation:

In Martin Luther King's "I Have a Dream" speech, the phrase "defaulted on this promissory note" uses a metaphor (comparing America's failure to fulfill civil rights promises to a financial default) to evoke strong feelings about justice and unfulfilled hopes. This appeals to the audience's emotion. "Character" (ethos) would involve appeals to the speaker's credibility, "humor" is not present here, and "logic" (logos) would use facts/reasoning, but this line is more emotional in its metaphorical appeal.

Answer:

A. emotion.
