Guy is walking down a long dirt road and comes to a fork in the road. One direction leads to a place called TRUTHVILLE where everyone ALWAYS tells the truth. The other way leads to a place called LIESVILLE where everyone ALWAYS tells a lie. There are no signs and no way to tell which direction leads to which town. The only thing is standing there is a little girl who happens to be standing right in the middle of the fork in the road. There is no way to tell which town she comes from. You can only ask the girl one question and one question only! What is the one question you can ask to be 100% certain she will give you the directions to TRUTHVILLE?
