A man is trapped in a room. The room has only two possible exits: two doors. Through the first door there is a room constructed from magnifying glass. The blazing hot sun instantly fries anything or anyone that enters. Through the second door there is a fire-breathing dragon. How does the man escape?
He waits until night time and then goes through the first door.
To solve this riddle and help the man escape, we need to consider the given conditions.
The first door leads to a room with a magnifying glass, which means that entering during the day would expose the man to the blazing hot sun, leading to instant frying. However, the man can use the properties of the magnifying glass to his advantage.
Since the riddle doesn't specifically exclude waiting until night time, the man can wait until it is dark outside. At night, the sun's intensity is reduced, and he can safely enter the room without being fried by the magnifying glass.
Therefore, the solution is for the man to wait until nighttime and then go through the first door, escaping the room without coming into harm's way.
