Why does the harlem poem starts with the question and ends with a question?

The Harlem poem, written by Langston Hughes, starts and ends with a question to draw the reader in and create a sense of momentum and exploration. The question at the beginning sets the tone and topic of the poem, while the question at the end leaves the reader with a sense of contemplation and reflection. By framing the poem with questions, Hughes encourages the reader to think deeply about the themes of the poem and consider the implications of the issues raised.
