Answer:
As soon as all the occupants have arrived, Miep must run off to get <u><em>ration books.</em></u>
Explanation:
"The Diary of a Young Girl" is an autobiographical memoir written by Anne Frank, a young Jewish girl who had to hide in a secret part of a building to escape capture by the Gestapo. The book, in the form of a diary, narrates the short yet detailed events of their hiding place and the time they spent there before they were discovered.
For the Franks and the Van Daans, hiding in the Secret Annex meant they had to sacrifice not only their freedom but also their normal chores. And to survive, they also required someone who is not a Jew to help them acquire certain necessities. Miep is one good family friend of the Franks and she was all-in when it comes to keeping them alive. So, as soon as the occupants of the Secret Annex have arrived, she hurried off to get some ration books for the Franks and the Van Daans, though not registered in their real names. These ration books are necessary documentation for a citizen in getting supplies.
