Riddle
30 minutes ago they made a riddle - I could not solve it = (. Since there were no riddles for a long time, I suggest you solve it:
In the room, upstairs, 3 switches. In the basement, below, 3 light bulbs. How in one trip to the basement to determine which switch belongs to which light bulb?
Good luck.
