What are two different conflicts in the novel and the resolution?

Hannah does not appreciate going to her Grandparents and celebrating Jewish holidays like Seder. By the end of the book she has a new appreciation for it.

Hannah does not know whether to rik her life or protect herself. Hannah risks execution when she speaks to Commandant Breuer about Reuven. Hannah's protective instincts take over and we can see some similarities between Reuven and Hannah's brother, Aaron. Unable to save him, Hannah is overcome with guilt and anger, wishing she was able to sacrifice more to save him or, failing that, join him in death.
