Final answer:
It is true that satirists may use irony, where they say one thing and mean another, to criticize and expose societal faults humorously yet effectively.
Step-by-step explanation:
The statement that a satirist may use irony to give the appearance of saying one thing while meaning another is indeed true. This literary technique helps to convey criticism and provoke thought in a manner that might not be immediately obvious. Satire employs tools like humor, exaggeration, and irony to ridicule or expose human follies, vices, or incompetencies.
Irony, in particular, involves stating something that typically means the opposite of what is being said, thus requiring the reader to reflect on the true meaning. For instance, Jonathan Swift's famous satirical work, 'Gulliver's Travels', uses both satire and irony to critique society and human nature. The true art of satire is to entertain the reader while simultaneously delivering a critical message often related to societal issues or human behavior.
