The last scene in the play reconnects with the very first. He tells Miep that he's going to go away. She begs him to stay, but we can't help but empathize with Mr.Frank.

I think the author chose to start the book 19 years before the main events of the story so the reader could absorb things. The author technically wanted the reader(s) to understand something before reading the real story.
b) to express formality
