Answer:
A) Improvisation and D) Syncopation
Explanation:
Langston Hughes's poetry was influenced by jazz, a type of music that became popular during the Harlem Renaissance and was mostly associated with African Americans. In this excerpt, we can appreciate two of its distinguishable elements.
Improvisation is present in the way Hughes uses dialogue. The lines resemble a "call and response" type of conversation (several speakers respond to each other). On the other hand, Hughes also uses syncopation, which refers to an unexpected interruption in the rhythm of the poem.
