The Enlightenment is best described as which of the following?

• A. A revival of religious zeal and emotional worship
• B. A political revolution for independence
• C. A scientific theory that contradicted religious belief
• D. A movement toward rationalism with knowledge from observation

Answer: (D)

The Enlightenment centers on using reason as the primary guide to knowledge and applying a method of inquiry that relies on observation and questioning of accepted beliefs. Thinkers of the era emphasized the scientific approach—testing ideas, valuing evidence, and challenging traditional authority—and then extended those habits of mind to politics, religion, and society. That combination makes the description of a movement toward rationalism with knowledge from observation the best fit, because it captures both the emphasis on reason and on evidence gathered through experience. The other options miss this broad intellectual shift: one points to religious revival, another to political independence, and the last suggests a single scientific theory opposing religion, which doesn’t reflect the wider, reasoned program of the Enlightenment.
