Describe one way that propaganda can appeal to people's emotions.

Well, in the deepest sense, propaganda is a mind game. It plays of peoples emotions - fear, hope, anger, frustration, sympathy - to direct an audience towards a desired goal.

One way it could appeal to your emotions: People are naturally attracted to conflict. It would appeal to your emotions if someone was arguing against an opponent. It would get you fired up. You would get frustrated or you would hope one of them would win.
