When the dust clears you find yourself sitting on the top of a huge pile of sand, in a circular room with three doors. The room is illuminated by a single shaft of light from the hole far above you. From nowhere, a deep booming voiceover explains 'Behind one of these doors is a clue to escape! But choose carefully… The door on the left has dangers behind, far greater than those behind the door on the left of the door on the right.'

Which door will you choose?
The door on the left of the door on the right
The door on the left of the door in the middle
The door right of the door on the right of the door on the left

Alternatively, you may try to find the corners of the circular room.
