Question

when king says that \we will be able to transform the jangling discords of our nation into a beautiful symphony of brotherhood\, he is using what rhetorical appeal/device? (\jangling discords\ means it doesnt sound nice)

logos

autithesis

parallelism

ethos

Explanation:

Antithesis is a rhetorical device that involves contrasting two opposite ideas in parallel structure. Here, "jangling discords" (unpleasant and dis - unified) is contrasted with "beautiful symphony of brotherhood" (harmonious and unified). Logos appeals to logic, parallelism is about similar grammatical structures, and ethos appeals to ethics or credibility. This statement doesn't fit those.

Answer:

B. antithesis
