2. A Straightforward Puzzle
There are three doors. One door leads to certain death, one door leads to untold riches, and one door leads to freedom. How do you determine which door to choose?
Ask the guard standing next to the doors which door leads to freedom. If the guard is honest, he will point you to the correct door. If the guard is dishonest, he will still point you to the door that leads to freedom, as that is the only way you will survive.
