John is trapped in a room. There is a table, a chair, 2 doors and a small hole in the ceiling (6 inches in diameter) there.
Behind the first door there’s an extremely hungry lion that hasn’t eaten for a couple of days. Behind the second door there’s a glass tunnel that magnifies the sunlight, and it creates such a high temperature that even opening the door could kill John. How will he escape?
The good answer:
He waits until it is night. He can see it through the hole in the ceiling! At night he canlescape through the glass tunnel.
