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?
