Problem: A traveler comes to a fork in the road which leads to two villages. In one village the people always tell lies and in the other village the people always tell the truth. The traveler needs to conduct business in the village where everyone always tells the truth. A man from one of the villages is standing in the middle of the fork, so there is no indication of which village he comes from. The traveler approaches the man and asks him just one question. From the man’s answer, he knows which road to follow. What is the question?
