Which part of the passage best conveys a mocking tone within the context of the passage? Satire

Satire is a literary genre that uses irony, exaggeration, and humor to ridicule and criticize an object or a person. Satire is often used to provide positive advice or improve the conditions of humanity by mocking the flaws in society. "The true end of satire," observes John Dryden, "is the amendment of vices by correction." A satire has no set literary form and can be written as a novel or as poetry. Anything can be satire, including an ode, a ballad, or even an elegy.
Some noteworthy satires in poetry are "Absalom and Achitophel" and "MacFlecknoe" by John Dryden, "Hudibras" by Samuel Butler, "Dunciad" by Alexander Pope, and "Vision of Judgment" by Lord Byron. Gulliver's Travels by Jonathan Swift is one of the finest satirical novels. Another brilliant example of satire is Adventures of Huckleberry Finn by Mark Twain, when Huck states, "What's the use you learning to do right, when it's troublesome to do right and isn't no trouble to do wrong, and the wages is just the same?" (chp. 16)
On the surface, a satire might appear humorous and entertaining. But that is not its true purpose. A satire's true purpose is to educate and warn people against negative things going on in society. By writing a satire, the author hopes to change the views of the readers and help them become better human beings.
