Imagine that you are forced to flee for your life down a long corridor. At the end of the corridor there are two doors, each attended by a robot. One door leads to certain death and the other to freedom, but you do not know which is which. You must make a decision as to which door to go through. Fortunately you are allowed to ask one and only one question of either of the two robots. However, one robot can only lie and the other can only tell the truth.
