Which statement best describes the aim of scientific investigations؟

• A. Explore a phenomenon and test a theory or model.
• B. Collect data solely to confirm personal beliefs.
• C. Observe without forming questions.
• D. Publish results without testing ideas.

Answer: (A)

The aim of scientific investigations is to explore a phenomenon and test a theory or model. In science, you begin by noticing something puzzling, asking questions, and proposing an explanation that makes testable predictions. Then you gather evidence through experiments or careful observations, analyze the results, and see whether the data support or challenge the theory. If needed, you refine the model and continue testing. This combination of investigating what happens and evaluating ideas against evidence is what makes this description the best fit. The other options miss important parts: data aren’t collected just to confirm personal beliefs, you don’t study without forming questions, and publishing results isn’t the end goal without testing ideas first.
