Read the following excerpt from henry david thoreau's "resistance to civil government."

men generally, under such a government as this, think that they ought to wait until they have persuaded the majority to alter them [unjust laws]. they think that, if they should resist, the remedy would be worse than the evil. but it is the fault of the government itself that the remedy is worse than the evil. it makes it worse.

which of these rhetorical devices does thoreau most clearly use here?

a. rhetorical question
b. ethos

d. metaphor
