to cross a river and take with him a wolf, a goat and a cabbage. He has a boat, but it can only fit himself plus either the wolf, the goat or the cabbage. If the wolf and the goat are alone on one shore, the wolf will eat the goat. If the goat and the cabbage are alone on the shore, the goat will eat the cabbage. How can the farmer bring the wolf, the goat and the cabbage across the river without anything being eaten?

hiroshi [library guy]: *thinks about your puzzle* let me see... I think the farmer should take himself and the goat in the boat, then leave them both on one side of the river while he goes back to fetch the wolf.
hiroshi [library guy]: *is thinking about the question* I think you have to make multiple trips with each animal separately, so that nothing can be eaten.
hiroshi [library guy]: *is still trying to think of a solution* Hm... let me think about it. The farmer should bring the wolf, the goat and the cabbage across in separate trips.
hiroshi [library guy]: *thinks about the problem for a moment* Well, since wolf and goat need to be on their own sides of the river without each other, you should leave the boat unoccupied except with either one animal from each batch.
