Answer:
Chapter 15 of "The Giver" by Lois Lowry begins with Jonas receiving memories of pain from the Giver. He experiences a broken leg, sunburn, and even sunstroke, which is a new and terrifying experience for him. The Giver explains that pain is a part of life, and that it is necessary to have both good and bad experiences to appreciate the full range of emotions.
Jonas then experiences a memory of war, which is a completely foreign concept to him. He is horrified by the violence and suffering that he witnesses, and he begins to question why such things would ever happen. The Giver explains that war is a result of human nature, and that it is something that has plagued humanity for centuries.
As Jonas continues to receive memories from the Giver, he becomes increasingly disheartened by the pain and suffering that he witnesses. He begins to feel that the burden of holding these memories is too great for one person, and he questions why he was chosen for this role.
The Giver then reveals to Jonas that the previous Receiver, who had failed ten years prior, was actually his father. Jonas is shocked and saddened by this revelation, and he realizes that his father has been lying to him and his family his entire life.
The chapter ends with Jonas feeling overwhelmed and burdened by the weight of the memories he has received. He wonders if he will ever be able to return to the innocence and ignorance of his former life, or if he will be forever changed by the knowledge he has gained.
Overall, Chapter 15 of "The Giver" is a pivotal moment in the novel, as Jonas begins to grapple with the full range of human emotions and experiences. He is forced to confront the reality of pain and suffering, and he begins to question the very foundation of the community in which he lives. The revelation about his father also serves to deepen his sense of isolation and loneliness, as he realizes that he cannot trust even his own family members.
