Ok, you wake up to see two doors in front of you, one door leads to heaven, and the other leads to hell, you do not know which. You must choose so that you may go to heaven. To find out which one of the doors is heaven and hell, you must ask a door any one question, but you can only ask one door. The door that leads to heaven will always tell the truth, but the door that leads to hell will always tell lies. So the riddle is, you must ask a question in order to find which door leads to heaven or hell. Example- "which door is the door to heaven?", by the way that is not the right question. First one to answer it correctly gets the points.
