Question

in what circumstances did the Franks have to go into hiding?

Answer 1

The Franks had to go into hiding because a call-up notice had come for Margot who was sixteen and the Nazis wanted to send away girls her age on their own. A call-up notice meant concentration camps and lonely cells this it became imperative for the frank family to move to their hiding place in confinement to a secret annex in Anne's father's office.
