What is the difference between expository and persuasive writing on HiSET?

• A. Expository explains; persuasive argues a position with evidence
• B. Expository argues; persuasive explains
• C. They are the same
• D. Expository is fiction; persuasive is nonfiction

Answer: (A)

The main idea being tested is how the two writing types differ in purpose and approach. Expository writing is about explaining information clearly: it lays out facts, definitions, steps, or processes so the reader understands how something works or why something happens. Persuasive writing, on the other hand, aims to convince the reader to accept a particular position or to take a specific action, and it builds a case with reasons, evidence, and often appeals to emotion or ethics.

On HiSET tasks, an expository piece would present information in an organized way—using structures like description, comparison/contrast, cause and effect, or problem/solution—without trying to push a personal stance. A persuasive piece would present a clear claim, support it with evidence, address counterarguments, and end with a call to action. Both styles use evidence, but the purpose shifts: explain and inform versus argue and persuade.

So the correct answer captures that difference: expository explains information; persuasive argues a position with evidence.
