* Hunting for food: This is the most basic act of rebellion. The Capitol controls food distribution, and Katniss's family is barely surviving on the rations they receive. By hunting illegally in the woods, she is directly defying the Capitol's control and providing for her family. This act is about survival, but it also demonstrates a rejection of the Capitol's authority.
* Volunteering as tribute: This is a major act of rebellion. When her younger sister Prim is chosen as tribute, Katniss volunteers in her place. This is not only an act of love and protection, but also a direct defiance of the Hunger Games themselves. By choosing death instead of letting her sister die, Katniss is signaling her opposition to the Capitol's brutal entertainment.
* Giving the three-finger salute: This is a symbolic act of rebellion. In the arena, Katniss and Peeta's defiance of the Capitol is shown through the three-finger salute, which is the symbol of rebellion against the Capitol. It is a gesture of defiance against the Capitol's control, and it becomes a symbol of hope for the districts.
These initial acts of rebellion are significant because they show that Katniss is not a passive participant in the Capitol's system. She is willing to break the rules and defy the Capitol, even if it means risking her own life. These early acts of rebellion foreshadow her later actions, which ultimately lead to the rebellion against the Capitol.
