Read the passage from "Why the Leopard Can Only Catch Prey on Its Left Side.” At one time leopards did not know how to catch animals for food. Knowing that the cat was very [skillful] in this way, Leopard one day went to Cat and asked very politely if she would teach him the art. Cat readily consented.

The first thing Leopard had to learn was to hide himself among the bushes by the roadside, so that he would not be seen by any animal passing by. Next he must learn how to move noiselessly through the woods. He must never allow the animal he chased to know that he was following it. The third great principle was how to use his left paws and side in springing upon his prey.

Having taught him these three things, Cat requested him to go and practise them well. When he had learnt them thoroughly he could return to her and she would give him more lessons in hunting.

What type of lesson does this passage teach?

A. the history of a tribe
B. a method of survival
C. an explanation of the natural world
D. interactions between humans and gods
