What does peer-review signal about a source?

• A. It is selected by random readers
• B. It is published without scrutiny
• C. It has undergone evaluation by domain experts
• D. It is guaranteed to be free of errors

Answer: (C)

Peer review is a step where experts in the field read and critique a manuscript before it gets published. This signals that the work has been evaluated by domain experts who assess its methods, data, and conclusions. It’s not a matter of random readers selecting it, nor is it published without any scrutiny, and it doesn’t guarantee that the article is completely error-free. The process aims to strengthen the work by catching problems and weighing the significance of the findings, though even peer‑reviewed articles can have limitations or remaining uncertainties.
