But if he leaves the goat with the cabbages alone on one side of the river the goat will eat the cabbages. If he leaves the wolf and the goat on one side the wolf will eat the goat. Only the farmer can seperate the wolf from the goat and the goat from the cabbage.
How can the farmer cross the river with all three items, without one eating the other ?
Send the goat across, then go back. Send the wolf across, and bring the goat back. Send the cabbage across, then go back. Finally, send the goat across again.
