"Till at last there was only one small fish left in all the sea, and he was a small 'Stute Fish, and he swam a little behind the Whale's right ear, so as to be out of harm's way. Then the Whale stood up on his tail and said, 'I'm hungry."
Explanation:
The part of the excerpt that best demonstrates that the author's purpose is to entertain children with a humorous story is the second one.
We have two animals that speak to each other as if they were people. Both of them could be amusing to children - one is a small fish, and the other is a big hungry whale that can stand on its tail. The story also has a rhythm, which makes the story more dynamic and interesting to children.
"In the sea, once upon a time, O my Best Beloved, there was a Whale, and he ate fishes. He ate the starfish and the garfish, and the crab and the dab, and the plaice and the dace, and the skate and his mate, and the mackereel and the pickereel, and the really truly twirly-whirly eel. All the fishes he could find in all the sea he ate with his mouth—so!"
