Read the passage from A Raisin in the Sun . MAMA ( sensing their facetiousness ) : What's the matter with you all? WALTER: Ain't nothing the matter with us. We just telling you 'bout the gentleman who came to see you this afternoon. From the Clybourne Park Improvement Association. MAMA: What he want? RUTH ( in the same mood as BENEATHA and WALTER) : To welcome you, honey. WALTER: He said they can't hardly wait. He said the one thing they don't have, that they just dying to have out there is a fine family of fine colored people! ( To RUTH and BENEATHA.) Ain't that right! RUTH (mockingly) : Yeah! He left his card— BENEATHA (handing card to MAMA) : In case. MAMA reads and throws it on the floor—understanding and looking off as she draws her chair up to the table on which she has put her plant and some sticks and some cord . MAMA: Father, give us strength. ( Knowingly—and without fun .) Did he threaten us? BENEATHA: Oh—Mama—they don't do it like that anymore. He talked Brotherhood. He said everybody ought to learn how to sit down and hate each other with good Christian fellowship. Which statement best summarizes the theme in this passage?
