Final answer:
Katniss throws the cookies out the window as an act of defiance against the Capitol and to show her loyalty to Peeta in 'The Hunger Games'.
Step-by-step explanation:
In the book 'The Hunger Games', Katniss throws the cookies out the window as an act of defiance against the Capitol. The Capitol had forced her to eat excessive amounts of food during her time in the arena, and throwing the cookies is her way of rebelling against their control. This action also shows that Katniss is not easily swayed or manipulated by the Capitol.
Katniss' relationship with Peeta is complex. While they start off as allies in the Hunger Games, their relationship evolves and becomes deeper. Katniss throwing the cookies out the window is symbolic of her loyalty and bond with Peeta. By rejecting the Capitol's food, she is rejecting their control over her and standing in solidarity with Peeta, who she cares deeply for.
