What does katniss thank district 11 for?

Katniss thanks District 11 for the bread that Rue's family threw her and Prim. This is a very powerful moment in the story, as it symbolizes the solidarity and compassion that exists between districts, even though they are separated and exploited by the Capitol.

While it seems like a simple gesture, the bread is a reminder of the humanity and kindness that survives even in the face of oppression. It also sets the stage for Katniss's eventual alliance with District 11 in the rebellion.
