Which action most strengthens the reliability assessment of a source?

• A. Cross-checking claims with multiple independent sources.
• B. Believing only the source that agrees with your views.
• C. Counting the number of pages in the source.
• D. Sharing the source on social media.

Answer: (C)

Cross-checking claims with multiple independent sources strengthens reliability because it tests whether the information holds up under scrutiny from different, unrelated perspectives. When several credible sources converge on the same point, it reduces the chance that a single biased, mistaken, or faulty source is driving the claim. Independent corroboration provides stronger evidence than any one source alone and helps identify inconsistencies or gaps in the information.

Length or page count doesn’t guarantee accuracy—long sources can still be false, and short sources can be highly reliable. Believing only sources that align with your views relies on bias rather than evidence, which weakens reliability. Sharing a source on social media spreads information but doesn’t verify its accuracy.
