Internal Conflict:
* The struggle to survive and maintain her humanity: Katniss faces constant pressure to be a symbol of rebellion, a "mockingjay," and to put the needs of the districts above her own. This internal conflict is fueled by her love for her family and her desire to protect them, battling with the need to sacrifice herself for the greater good. She struggles to remain kind and compassionate in a world that forces her to be ruthless.
External Conflict:
* The fight against the Capitol and the Games: Katniss faces an immediate and constant threat from the Capitol, which seeks to control and manipulate her. The Hunger Games themselves are a brutal external conflict, where she must fight for survival against other children and the Capitol's machinations. This conflict is made more complex by the Capitol's use of propaganda and manipulation to pit the districts against each other.
These are just two examples, and there are many other internal and external conflicts within the story of The Hunger Games.
