Question: A farmer with a vegetarian wolf, a carnivorous goat, and a cabbage must cross a river by boat. The boat can carry only the farmer and a single item. How can they cross the river safely? Copilot: This classic river crossing puzzle can be solved with careful planning to ensure that none of the passengers eat each other. Here's a step-by-step solution: 1. First Trip: The farmer takes the goat across the river and leaves it on the other side. The goat is safe to leave alone, and this prevents it from eating the cabbage or being eaten by the wolf. 2. Return Trip: The farmer returns alone to the original side to pick up another passenger. 3. Second Trip: The farmer takes the cabbage across the river next. He leaves the cabbage on the other side but brings the goat back with him to the original side. This is because if he left the goat with the cabbage, the goat would eat it. 4. Return Trip: The farmer leaves the goat on the original side and takes the wolf across the river. Va He leaves the wolf with the cabbage on the other side. The wolf won't eat the cabbage because it's carnivorous, and the cabbage is safe. 5. Final Trip: The farmer returns alone to pick up the goat. He then takes the goat across the river one last time. Now, all three are safely on the other side of the river. The farmer managed to transport all his belongings without any harm coming to them. The key is to never leave the goat alone with the cabbage or the wolf alone with the goat.
