Answer: to inform the audience of Gies’s remarkable acts.
The purpose of the excerpt is to inform the reader of the remarkable acts of bravery of Gies. Although her main action (that of hiding the Franks) is well-known, the author wants to bring attention to her other actions, such as sneaking back to the hideaway and retrieving the diary. These actions show that she was a brave and special woman.
