Which statement describes how a hypothesis is tested?

• A. A hypothesis is tested and results determine support or refutation.
• B. A hypothesis is always proven true.
• C. Results cannot affect a hypothesis.
• D. Hypotheses are irrelevant to the investigation.

Answer: (A)

The idea being tested is how a hypothesis is evaluated through experiments and data. A hypothesis gives a testable prediction, and when you collect and analyze results, you see whether the data align with that prediction. If they do, the hypothesis is supported; if they don’t, it’s refuted or revised. In science, hypotheses aren’t proven true beyond all doubt—evidence accumulates to support them or lead to modification. The other statements don’t fit how testing works: results can affect a hypothesis, and hypotheses are central to guiding investigations.
