Which term refers to the period when developments in mathematics, physics, astronomy, biology, and chemistry transformed views of nature?

• A. Secondary sources
• B. Rule
• C. Sectionalism
• D. Scientific Revolution

Answer: (D)

This question is asking about a period that brought a fundamental change in how people understood nature, across math, physics, astronomy, biology, and chemistry. In this era, scientists began using careful observation, experiments, and mathematical reasoning to uncover natural laws, moving away from relying solely on ancient authorities. The result was a new way of explaining the physical world as governed by testable theories and universal laws, which reshaped views about the cosmos, matter, and life. That transformative period is known as the Scientific Revolution. The other terms don’t describe a historical shift across multiple scientific fields; they refer to things like types of sources, rules, or political divisions.
