Question

read the descriptions of rhyme schemes below.
free verse: poetry that does not use a consistent rhyme scheme
iambic pentameter: a poetic rhyme scheme in which each rhyming line has ten syllables
blank verse: poetry that uses unrhymed iambic pentameter
rhyming couplets: a series of two consecutive lines that rhyme in a poem
based on the descriptions, what rhyme scheme does the poem \harlem\ use?
free verse
iambic pentameter
blank verse
couplets

Explanation:

"Harlem" by Langston Hughes does not follow a consistent rhyme scheme. Free verse is defined as poetry without a consistent rhyme scheme. Iambic pentameter requires ten - syllable rhyming lines (not the case here). Blank verse is unrhymed iambic pentameter (but "Harlem" doesn't follow iambic pentameter). Couplets are two - line rhyming units (not present in "Harlem"). So, based on the definitions and the nature of "Harlem", it uses free verse.

Answer:

Free verse
