Answer:
1. As Amir and Farid travel north to his father's house, they see a dead body and a man selling his artificial leg.
2. Assef fights with Amir and hurts him badly, but Amir is saved by Sohrab who, like his father, uses a slingshot and incapacitates Assef. Amir and the boy escape with Farid.
3. In the letter, Rahim Khan admits that he knows all that had happened during the running of the kites. He also explains that Amir was a physical representation of Baba's guilt; that is, although Baba loved both Hassan and Amir — his two sons — he was unable to demonstrate openly his love for Hassan.
4. At the end of the story, Soraya says Amir must bring Sohrab back with him, and she is excited to meet him. Amir finally confesses his past to Soraya, as he should have done the day of their engagement when she told him the story of her past relationship.
5. Farid drives Amir to Baba's house. It is falling apart, but recognizable. Amir finds his bedroom window and remembers looking out of it to watch Ali and Hassan the morning they left. He goes up the hill to the pomegranate tree where he and Hassan used to play, but Farid tells him they should leave.
