Question

The diary of Anne Frank is a legacy Miep Gies gave not just to Otto Frank, but to the world. It's been translated into some 65 languages and remains one of the best read books internationally. To the end of her century of life, Gies said she thought with sadness every day about the friends she had lost.
On her website she wrote it was her greatest sorrow that she and the others had been unable to save Anne, but she was pleased they'd been able to give the young woman two more years of life, and in that period Gies noted, Anne had written the diary with her message of tolerance and understanding.

What is the purpose of this excerpt?

to honor Miep Gies and share her history with the audience
to tell an interesting story and encourage people to help others
to preserve the memory of Anne Frank and advocate tolerance
to promote doing the right thing and remember the Holocaust

Answer 1

Im guessing it is the third one. To preserve the memory of Anne frank and advocate tolerance. That should sound  about right
