Read the excerpt from The Diary of Anne Frank. Miep. I made up the beds . . . the way Mr. Frank and Mr. Kraler said. (She starts out.) Forgive me. I have to hurry. I've got to go to the other side of town to get some ration books for you.
Mrs. Van Daan. Ration books? If they see our names on ration books, they'll know we're here.
Mr. Kraler. There isn't anything . . .
Miep. Don't worry. Your names won't be on them. (As she hurries out) I'll be up later.

Why is it important that the Van Daan and Frank family names do not appear on the ration books?

The families do not believe in the ration books system, because it is unfair.
The families are getting extra rations, and they do not want anyone to know.
The families are in hiding, so no one can know they are receiving rations.
The families do not understand the ration system, so they do not want to be a part of it.
