Victoria, The Chosen is a wonderful book. Once you have read it through, go back through it and make some notes in regards to when the author reveals what the boys are wanting to do with their futures.
Did you agree with what they had chosen to do? Would you have made the same decision? No one here will be giving you the answers to your homework, we will only make suggestions as to where to look. The teacher is looking for what you think, not what we think. Good luck.
