Answer Key and Explanations

Check these only after attempting every question.

1. B - Inspect the proposed action and its evidence, then approve, edit, or refuse before it executes

Approval that cannot prevent execution is theatre, not control.

2. B - Immediately before the consequential action

The pause must sit at the point where refusal still changes the outcome.

3. B - Resume using the edited state, not the original proposal

If the edit is not carried into state, the human intervention is silently ignored.

4. B - Reviewers rubber-stamp everything when asked too often, so the control stops working

Gate the consequential steps, not every step, or the gate becomes a reflex click.

5. B - What will happen, to whom, based on what evidence, and how to refuse

A reviewer can only be accountable for a decision they were given enough context to make.

Practical Check

Apply this module to your own work: complete the module activity for *Human-in-the-Loop Review and Edits*, then write one sentence naming what your result shows and one naming what it does not.

Strong Answer Pattern

A strong answer names the task, the evidence used, the check performed, and the remaining limitation. It avoids "proved", "guaranteed", or "always" unless the evidence genuinely supports it.
