Devices for persuaders

The sentence is phrased as a question but does not expect a literal spoken answer, which is the hallmark of a rhetorical question.

Rhetorical questions are used to lead an audience toward a conclusion the speaker already wants them to reach.

By framing the situation as unfair, the speaker nudges listeners to agree internally that change is needed.

The effect is to prompt silent agreement rather than any literal action, matching the choice “It invites listeners to silently agree that the situation is unjust, without expecting a spoken reply”.

The speaker is not calling for an actual vote in that moment, so the choice “It asks the audience to literally raise their hands and vote on the question right away” misreads the device as a call to action.

No statistics or facts are given here, so the choice “It provides factual evidence about how the cafeteria menu decisions are currently made” does not describe what the sentence does.

The question stays directly on topic about menu fairness, so it does not distract as the choice “It distracts the audience from the main argument by introducing an unrelated topic” suggests.

The choice “It invites listeners to silently agree that the situation is unjust, without expecting a spoken reply” best captures the persuasive function of leading the audience to a silent judgement.

The choice “It invites listeners to silently agree that the situation is unjust, without expecting a spoken reply” is correct.

The word 'every' is repeated at the start of three short phrases, which is a structural repetition device.

Repetition builds rhythm and drums an idea into the audience's memory, increasing emphasis.

Here it emphasises that no piece of litter, however small, should be dismissed as unimportant.

This matches the choice “Repetition of 'every' to build rhythm and emphasise that no piece of litter is too small to matter” exactly.

There is no personal story or narrative told, so the choice “An anecdote that recounts a personal story about a specific time the speaker picked up litter” does not fit the quoted lines.

No historical event or external reference is mentioned, ruling out the choice “An allusion that references a well-known historical event connected to environmental cleanup efforts”.

The lines do not instruct the audience to do anything specific, so the choice “A call to action that directly tells the audience to go outside and pick up litter” is incorrect.

Only the choice “Repetition of 'every' to build rhythm and emphasise that no piece of litter is too small to matter” correctly names the repeated structure and its emphasis effect.

The choice “Repetition of 'every' to build rhythm and emphasise that no piece of litter is too small to matter” is the correct device and effect.
