A man was stuck in a dungeon and the three doors are the only escape routes. He got a sufficient supply of buckets filled with food, medicines, and water to drink for a week.

The first door leads to a 5-meter wall of fire.
The second door leads to a hungry bear and his cub.
The third door leads to a lake filled with crocodiles.

How can a man escape?

The Three Door Riddle

The first door.

The bear will try to protect the cub, even if you offer her your food.
Swimming a lake with crocodiles is definitely not a good idea.
You can use your bucket to fight the fire with the water from the lake and can also distract the crocodiles with the food you had.
