Part II : Give at least two specific examples of how Katniss acted differently in the arena (than she normally would) because of the cameras.

Katniss does not alter her personality much for the cameras. That is partly why she is so popular with people in the Capitol. Katniss plays up the romance between her and Peeta. She kisses him when she is taking care of him in the cave and makes sure the cameras see it. I don't think she wanted to kill herself with the berries at the end of the book but needed that display to save both her and Peeta.
