B. Please read the Fable below

One day the Fox thought of a plan to have some fun, by poking fun at the Stork, whose strange appearance he had always thought was funny.

"You must come and dine with me today," he said to the Stork, smiling to himself at the trick he was going to play. The Stork gladly accepted the invitation and arrived smiling and ready for dinner

For dinner the Fox served soup. But it was set out in a very shallow dish, and all the Stork could do was to wet the very tip of his beak. He could not get a drop of soup. But the Fox lapped it up easily, and, to annoy the Stork further, made a great show of enjoying his meal.

The hungry Stork was much displeased at the trick, but he was a calm, even-tempered fellow and saw no good in flying into a rage. Instead, not long afterward, he invited the Fox to dine with him in turn. The Fox arrived at the time that had been set, and the Stork served a fish dinner that had a very appetizing smell. But it was served in a tall jar with a very narrow neck. The Stork could easily get at the food with his long beak, but all the Fox could do was to lick the outside of the jar, and sniff at the delicious scent. And when the Fox lost his temper, the Stork said calmly: Do not play tricks on your neighbors unless you can stand the same treatment yourself.
