Final answer:
Verified information from multiple reputable sources option (b) is not a sign that content is unreliable; it indicates that the information is accurate and credible.
Step-by-step explanation:
Among the options provided, the one that is NOT a sign that what you're reading about is "fake" or unreliable is b. Verified information from multiple reputable sources. This assures us that the information has been confirmed by several credible entities, suggesting it is likely to be accurate. On the contrary, misleading sources, lack of author transparency, and poorly or un-cited information are all red flags that suggest a source may not be reliable.
When evaluating sources, it's important to consider the author's credentials, the presence of bias, if the source cites its information properly, and whether other reputable sources corroborate the information. For content gleaned from the Internet, particular scrutiny is required as almost anyone can publish content online. Key considerations include the author's qualifications, whether the information is well-cited, and if the author's affiliations are disclosed.
