Read the following excerpt from "Woman Who Helped Hide Anne Frank Dies at 100" by Teri Schultz. SCHULTZ: That day would never come, as Anne did not survive the Nazi death camps. But Otto Frank did. And he made his way back to Amsterdam in 1945 returning to stay with Gies and her husband. On the very sad day that year that he learned both his daughters had died in a camp, Otto Frank later explained in a documentary, Gies delivered him what he called a miracle.
Which answer best paraphrases the central idea of the excerpt?
After he returned to Amsterdam, Otto Frank learned that his two daughters did not survive the death camps.
Miep gave Anne’s diary to Otto Frank on the day he learned that his daughters died in the death camps.
There is a documentary in which Otto Frank described the day when Miep gave him Anne’s diary.
Because Anne did not survive the death camps, the preservation of her diary is a miracle.
