Imagine yourself in a room with three switches. In the adjacent room there are three light bulbs (or table lamps placed on ordinary tables) - they are not lit. Each switch controls a desk lamp. You can't go from room to room. If you can only enter a room with the light on once, how do you know which switch has which light? Your task is to determine all three switches (i.e. what bulbs are connected to switches 1, 2 and 3). Respond with more than 6 words be in all capital letters.
