A teacher is reviewing student assignments and keeps finding incorrect facts supported by unreliable sources. What should the teacher explain to the students about finding online sources?

Checking if a website looks reputable and professional is a practical first step in evaluating online sources. This involves looking for clear authorship, an "About Us" section, contact information, a professional design, and an absence of excessive ads or sensational language. While not foolproof, these indicators often correlate with more reliable information. Option A, verifying all online information with textbooks, is impractical and time-consuming for every piece of information. Option B, contacting the author directly, is rarely feasible for students and doesn't scale. Option D, distrusting all online information, is an extreme and unhelpful stance, as the internet contains vast amounts of credible information.
