Answer:
The skin of man.
Step-by-step explanation:
Jomo Kenyatta's short story "The Gentlemen of the Jungle" is about how an animal commission decided the trial of a man who had 'accused' an elephant of 'kicking' him out of his hut. The case was brought to the king of the jungle who formed the commission to 'solve' the case.
On a rainy day, an elephant who had befriended a man requested him to let him put his trunk inside his hut. And with that permission, he eventually drives out the owner of the man from his hut. The reason, according to the elephant, was that "your skin is harder than mine, and as there is not enough room for both of us, you can afford to remain in the rain while I am protecting my delicate skin from the hailstorm." This shows that the elephant believes human skin is harder than an elephant's skin.
