What type of writing frequently uses humor to criticize societal issues?

The correct answer is satire, which is a genre of writing known for its use of humor, irony, and exaggeration to critique and expose the flaws in societal norms, behaviors, and institutions. Satire often aims to provoke thought and inspire change by highlighting the absurdities or contradictions within society. Well-known examples of satire include works by authors like Jonathan Swift and George Orwell, where serious topics are addressed in a way that engages readers through wit and humor.

In contrast, a soliloquy is a dramatic device where a character speaks their thoughts aloud, usually in a play, and does not inherently involve humor or societal critique. A sestet is a form of poetry consisting of six lines and is not specifically aligned with satire; it could cover various themes without the necessity of humor or criticism. Hyperbole refers to exaggerated statements or claims not meant to be taken literally, and while it can be a component of satire, it does not encompass the broader context of critiquing societal issues.
