Rhetorical Questions in an Argument Versus an Explanation

A rhetorical question does one job: it presses an answer the reader has already been steered toward. 'What could matter more than clean water?' only lands if the essay has already built the case that clean water matters more than the cost, the effort, or the alternative. That's why the question belongs in argument, where the whole point is to move the reader toward a position. An explanation has no position to press. It just lays out how something works or how something was built, so a rhetorical question dropped into it stalls — there's no claim for the reader to agree with, just information to absorb.

This is also why placement matters as much as genre. A paragraph that describes water testing and taste without ever stating a claim hasn't earned the question yet. The question assumes the reader already accepts a value judgment, and if the essay hasn't stated one, the question is pressing on nothing. A rhetorical question is not an automatic strong opener or closer. Grabbing attention isn't the same as doing rhetorical work — the question has to assume something the passage has actually supplied.

On a whole-passage or paired-essay question, this distinction is how you tell an argument from an explanation fast: look for whether the piece is pressing a value or laying out a process. In a narrative, a rhetorical-looking question works differently again. 'What was I doing here?' doesn't press the reader toward a claim — it reports a moment of doubt the writer felt. Same sentence shape, different job: record a thought versus push an argument.
