“You have just purchased three things at the local market: a wolf, a duck, and a bag of seeds. To get back home you must travel across a river in a small boat. You are only allowed to have one item with you on your boat at any time. You cannot leave the wolf alone with the duck, because the wolf will eat the duck.
