what details do you find on westerbork in the diary of anne frank?

From the text:

It must be terrible in Westerbork. The people get almost nothing to eat, much less to drink, as water is available only one hour a day, and there's only one toilet and sink for several thousand people. Men and women sleep in the same room, and women and children often have their heads shaved. Escape is almost impossible; many people look Jewish, and they're branded by their shorn heads.
