Which statement best describes the nature of science?

• A. The natural world is understandable.
• B. Science is based on consensus without review.
• C. Scientific ideas are permanent and never change.
• D. Science is not influenced by evidence.

Answer: (A)

The main idea being tested is that science aims to understand how the natural world works by using evidence and reasoning, with explanations that can be tested and refined over time. The statement that the natural world is understandable captures this goal: scientists work to build explanations and models that illuminate phenomena and allow us to predict what will happen in similar situations. This understanding isn’t static; as new evidence appears, explanations can be revised to better fit what we observe, which is a natural part of scientific progress. Why the other ideas don’t fit: science is not about consensus without review—claims must be supported by evidence and subjected to evaluation by others. scientific ideas are not permanent and never-changing; they evolve when new data suggest better explanations. science is driven by evidence and can be revised or overturned when evidence contradicts current ideas, not insulated from it.
