Given that this sounds like a cheap way to complete some homework assignment, I'm not going to give you 100 word but a general idea.
Anne's diary gives us some good insight into the concerns of a girl in hiding. The horror she truly felt isn't recorded, since concentration camps kinda/sorta don't allow that, plus she didn't have time or the mental energy; however, she did display an awareness of her situation which paints to us how much they did know and how little they anticipated the horror was going to be.
It also gives us insight into the thoughts of a young girl, transcending time to where we could believe that she could've lived in our time.
