Suppose you are in a land where orcs only tell lies, and elves only tell the truth. On your way to Gondor, you come across a fork in the path, going two seperate ways. One path leads you to Gondor, while the other leads you to some place else. There is also an orc and an elf standing around to answer any questions. Suppose you are allowed to ask just one question. What question do you ask to know that you take the correct path to Gondor?
