Question: You are walking down the road trying to find enlightenment when you come to a monk and a three-way fork in the road. The roads point North, East, and West. You can ask the monk one question. He will answer honestly yes, no, or just hum if he cannot answer the question.
What do you ask him to figure out the correct path?
Answer: If the treasure is not in the East, is it in the West? If the monk answers yes, it is West. If he answers no, it is East. If he hums, it is North.
