The term 'valid' when evaluating evidence means it is

• A. Based on rumors.
• B. Based on sound reasoning and credible support.
• C. Based on personal preference.
• D. Based on unreliable data.

Answer: (B)

Valid evidence means the claim rests on sound reasoning and credible, verifiable support. It shows a clear, logical link between the data and the conclusion and comes from reliable sources or data gathered through proper methods. When evidence is based on rumors or personal preference, it lacks verification and objectivity, making it unreliable for drawing conclusions. Similarly, relying on unreliable data leads to weak or misleading results because the data itself may be flawed. The strongest evidence blends solid logic with trustworthy sources, such as well-conducted studies or credible records, where the reasoning directly connects what’s observed to what’s being claimed.
