What word describes facts such as measurable data indicating whether a belief is true?

• A. Observations
• B. Relative dating
• C. Chronological
• D. Evidence

Answer: (D)

When deciding whether a belief is true, you rely on evidence—the facts and measurements that support or challenge the claim. Evidence is the data you collect, such as measurements, observations, and records, that help you determine if something is accurate. It’s broader than just what you notice in a single moment; it’s the body of information you can use to justify conclusions.

Observations are pieces of information you gather, which can be part of evidence, but the term evidence captures the idea of all facts and data that back up or oppose a belief. Relative dating and chronological refer to figuring out when things happened in time, not to evaluating whether a claim is true, so they don’t fit this context.

For example, if you’re testing whether a plant grows better with more sunlight, measurements of plant height and time to flowering provide evidence about the effect of sunlight. That collection of measurable data is what you use to determine the truth of the belief.
