Which of the lines from "Harlem” uses a metaphor, rather than a simile, to describe a dream deferred? Or fester like a sore—
Does it stink like rotten meat?

Explanation:

All the other lines use the word "like," which means that it is a simile. Similes use the words "like" or "as," metaphors don't. Since there is no "like" or "as" in "or does it explode," it is a metaphor.
