answer: #Person1# suggests #Person2# doing the art project by showing the same subject in different materials to show the advantages and disadvantages.
documents: #Person1#: What are you going to do for the project?
  #Person2#: I don't know. I was hoping you could help me think of something.
  #Person1#: Well, you're such a good artist. You could talk about watercolor while you're doing one in front of the class.
  #Person2#: Maybe, but what if I make a mistake in front of everyone?
  #Person1#: Come on, you're really talented. Besides you wouldn't have to do much preparation before hand.
  #Person2#: True.
  #Person1#: Or how about this? You could bring in a photo, a pencil drawing and watercolor of the same subject. Something simple so it wouldn't take so much time to do like a flower. Then you could show the advantages and disadvantages of working with different materials.
  #Person2#: I could do that ahead of time.
  #Person1#: You could, but remember it would take a lot more time.
  #Person2#: Sure. Thanks.
