There was a farmer who wanted to go across a river. The farmer had a dog, a goat, and some cabbage. The farmer’s boat was very small so the farmer could only take one thing across the river at a time.

 The problem was that if the goat were left alone with the cabbage, then the goat would eat the cabbage. If the dog were left alone with the goat then the dog would eat the goat. How can the farmer get everything across the river????
