Probably everyone has heard this one before: You’re standing in a hallway with three light switches on the wall, each of which turns on a different lamp inside a closed room. You can’t see inside the room, and you can’t open the door except to enter the room. You can enter the room only once, and when you do, all the lamps must be turned off. How can you tell which switch turns on which lamp?
Last week's answer: Take the first letter of each word and place it at the end. It will spell the same word backwards. So you had it right, Christina!
