Read the excerpt from The Diary of Anne Frank. Mr. Frank. First let us take off some of these clothes. (They all start to take off garment after garment. On each of their coats, sweaters, blouses, suits, dresses, is another yellow Star of David. Mr. and Mrs. Frank are underdressed quite simply. The others wear several things, sweaters, extra dresses, bathrobes, aprons, nightgowns, etc.)

Why did Anne and her sister most likely wear so many layers of clothing?

They were worried about being cold during the walk.
They were bringing extra garments for the Van Daan family.
They could bring into hiding only what they could carry.
They did not want to leave anything behind that could get stolen.
