You are stuck in a room with only 2 ways out, 2 different doors. One door leads to happiness, prosperity, etc.; the other door leads to depression, death, etc. Now there are 2 guards in the room. One lies, and one tells the truth, although you do not know which one tells the truth or tells the lies. What ONE question can ask ONE of the guards and know which door will lead you to happiness, prosperity, etc.?
