Answer:
Langston Hughes's poem "Harlem" poses a question "what happens to an unaccomplished dream that is put on hold"?. At first glance, we don't know about what dream does the author writes, but, from his political activism and the poem's title, we can conclude that he speaks of dream of African-Americans about social equality. So, what happens to that dream? Does it dry up like a raisin in the sun? Does it shrink? Does it explode?
"A raisin in the sun" is a play written by Lorrain Hansberry which deals with the life of African-American family, the Youngers.
The use of this line from the poem as a title for her play, obviously suggests a certain connection. The Younger family was very unpleasantly welcomed after moving to an apartment in an "all-white" neighborhood, which can be connected to the theme of Hughs's poem and the social inequalities.
Also, every member of the Youngers had a dream, a driving force responsible for their actions and the story. Having failed to fulfil them, the family is, at the end of the play, facing a very uncertain future. We could say that Hansberry left us with unanswered questions "What will happen to thin unfulfilled, referred dreams?" and "What consequences and impact will they have on family's future?".
