Final answer:
In both alternate endings, the characters' actions are consistent with their development throughout the book, reflecting themes of love and sacrifice.
Step-by-step explanation:
Option 1: Peeta dies in the arena and Katniss survives
In this alternate ending, Peeta's sacrificial act ultimately leads to his demise. Katniss, devastated by his death, finds renewed strength and determination to fight against the Capitol. With the memory of Peeta's love, she becomes the symbol of rebellion and goes on to lead the rebellion to victory.
Throughout the story, Peeta's love for Katniss is evident, and his sacrifice for her demonstrates his selflessness. This ending is consistent with the characters' development and the overall theme of love and sacrifice.
Option 2: Both Katniss and Peeta die in the arena
In this ending, Katniss and Peeta's love for each other leads them to make a final, desperate decision. Unable to bear the thought of living without each other, they consume the poisonous berries together, defying the Capitol's attempt to control and manipulate them.
This ending reflects the characters' defiance and refusal to be pawns in the Capitol's games. It also underscores the extent of their love and the lengths they are willing to go to protect each other.
