Read the passage from A Raisin in the Sun.BENEATHA goes to the door and opens it as WALTER and RUTH go on with the clowning. BENEATHA is somewhat surprised to see a quiet-looking middle-aged white man in a business suit holding his hat and a briefcase in his hand and consulting a small piece of paper.MAN: Uh—how do you do, miss, I am looking for a Mrs.— (He looks at the slip of paper.) Mrs. Lena Younger? (He stops short, struck dumb at the sight of the oblivious WALTER and RUTH.)BENEATHA (smoothing her hair with slight embarrassment): Oh—yes, that's my mother. Excuse me. (She closes the door and turns to quiet the other two.) Ruth! Brother! (Enunciating precisely but soundlessly: "There's a white man at the door!" They stop dancing. RUTH cuts off the phonograph, BENEATHA opens the door. The man casts a curious quick glance at all of them.) Uh—come in please. MAN (coming in): Thank you.
