Answer:
An author can use satire to express a complaint about society or politics in an entertaining way. This will help the author express his opinions and thoughts clearly while also providing entertainment to the readers.
Step-by-step explanation:
Satire is using irony, exaggeration, and humor to the issue(s) that an author may want to talk about but in an entertaining way. Through this literary technique, an author can ridicule or make fun of any issues pertaining to social, political, or even personal things that he/she wants to emphasize upon.
Satire provides an open platform for a writer to talk openly about issues that need to be addressed, but also in a humorous way so as not to be too serious. The humorous manner provides a means of addressing the follies of a person or a society but still manages to bring to light serious issues.
One example of the use of satire to express a complaint about society or politics is Jonathan Swift’s "Gulliver’s Travels".
