Lorraine Hansberry opens her play "A Raisin in the Sun" with the poem "Harlem (A Dream Deferred)" by Langston Hughes. The title of the play is clearly an allusion to the poem. Write an essay in which you explain how the play illustrates the theme of the poem. Discuss specifically the different characters and their dreams in relation to the two works. Use concrete examples, details, and quotations from both works, and fully explain the literary elements that appear.
