You're on a path which just so happens to come to a fork. You know that one way leads to death and one way leads to life, but you have no idea which way is which. It also just so happens that at this fork, there stands a set of twins—one of which ALWAYS lies and one of which ALWAYS tells the truth. They are, however, identical twins and there is no feasible way to know which one is which. You are allowed one, and only one question to ask, which both of the twins will answer. From their responses you must choose which path to take...

What way would the other twin say if I asked him the way to life?
You then take the opposite path.
(The liar will always tell you the wrong way )
