As the old woman leaves for a night on the town, she tells you that she has three rules regarding the children’s playtime: (1) they can play with whatever toys they want, but they have to clean their playroom before bedtime; (2) they should share their toys with each other; and (3) they are not allowed to fight with each other. Using the principles of reinforcement and punishment, devise a strategy to fulfill her three requests.
