Read the excerpt from The Diary of Anne Frank. Mr. Frank. Mrs. Van Daan, Mr. Van Daan, Peter. (Then, in explanation of their lateness) There were too many of the Green Police on the streets . . . we had to take the long way around. (Up the steps come Margot Frank, Mrs. Frank, Miep (not pregnant now), and Mr. Kraler. All of them carry bags, packages, and so forth. The Star of David is conspicuous on all of the Franks' clothing. Margot is eighteen, beautiful, quiet, shy. Mrs. Frank is a young mother, gently bred, reserved. She, like Mr. Frank, has a slight German accent. Mr. Kraler is a Dutchman, dependable, kindly. As Mr. Kraler and Miep go upstage to put down their parcels, Mrs. Frank turns back to call Anne.) Which best explains the purpose of the underlined stage direction?
