Scientists know about a subject and ask specific questions using the scientific method.

• A. Observational/Descriptive Science
• B. Hypothesis-Driven Science
• C. Scientific Method
• D. Theory

Answer: (B)

Formulating a testable hypothesis based on what is known and then testing it through experiments or controlled observations captures the essence of hypothesis-driven science. This approach starts with a specific question and a prediction that could be proven wrong, guiding the design of experiments to confirm or refute it. It moves beyond simply describing what’s observed and uses the scientific method to actively test ideas. Observational/descriptive science describes patterns without forcing a testable prediction, the broader scientific method covers the overall process, and a theory is a well-supported explanation built from many tested ideas—not the act of proposing and testing a single question. So this choice best fits the idea of scientists using the method to ask specific, testable questions.
