Which factor best indicates a source is reliable and relevant?

• A. The length of the article.
• B. Author qualifications, publication venue, date, bias, and whether evidence is supported by data or credible references.
• C. Whether it supports your view.
• D. The number of pictures.

Answer: (B)

Evaluating a source’s reliability and relevance means looking at who wrote it, where it was published, when it was published, whether there’s bias, and whether the claims are backed by solid evidence. Author qualifications show that the writer has the expertise to discuss the topic, which increases trust in what’s being said. The publication venue matters because reputable journals and established outlets usually have editorial standards that help catch errors and require credible sourcing. The date of publication is important because information can change over time; current sources are often more accurate for ongoing or evolving topics. Noticing bias helps you understand how the perspective or purpose of the piece might shape the information, so you can weigh it appropriately. Finally, evidence support—data, statistics, and references to credible sources—demonstrates that the claims are grounded in verifiable information rather than opinion alone.

Length or the number of pictures aren’t reliable indicators of quality, and a source that aligns with your own view may signal bias rather than credibility.
