Answer:
D. Mao provides an understanding of the word when he lists the opposites to his definition.
Explanation:
This is the quote that the question references:
<em>“A revolution is not a dinner party, or writing an essay, or painting a picture, or doing embroidery; it cannot be so refined, so leisurely and gentle, so temperate, kind, courteous, restrained and magnanimous. A revolution is an insurrection, an act of violence by which one class overthrows another.”</em>
In this quote, Mao does not provide any synonyms of the word "revolution." He also does not talk about the etymology (origin) of the word, nor does he compare the terms "revolution" and "resistance." However, something that Mao does is listing things that he considers to be opposite to the revolution. By doing so, he provides an understanding of the word.
