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 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.
