A cleaner visits an office block that uses three lamps to illuminate the main reception area. They are all turned off and the switches are in the entrance hall, from where it is not possible to see into the reception area. Alone in the building, she goes to the entrance hall, uses the switches, then proceeds immediately to the reception area, where she is then able to determine which light switch turns on which lamp. How does she know? |
