#1134: Logic Boat explain

Logic Boat

[A person shows up at a boat docked at the edge of a river. The person has brought along a head of cabbage, a goat, and a wolf.]

Problem: The boat only holds two, but you can’t leave the goat with the cabbage or the wolf with the goat.

[The wolf looks curiously at the cabbage that’s been left behind while the person goes off with the goat.]

Solution: 1. Take the goat across.

[The goat remains tied up on the far side. The wolf watches the person come back.]

  1. Return alone.

[The wolf sits and waits as the person goes off.]

  1. Take the cabbage across.

  2. Leave the wolf. Why did you have a wolf?

[The wolf goes off.]
