"Hmm...ok." You follow the short lady to her house. It's a
mansion, that's probably as old as her. You go inside and it looks
even older than the outside. "In order to get your money,"
say the lady. "You must perform for me a task. You have your
choice of tasks, but you only get to pick once." The old lady
goes into a dusty brown closet and takes out 3 scrolls. She she them
down on 3 specific stools; one's green, one's blue, and one's purple.
Which one should you pick??
