The time when human beings first domesticated plants and animals and no longer relied entirely on hunting and gathering.

• A. Neolithic Revolution
• B. Industrial Revolution
• C. Scientific Revolution
• D. Agricultural Revolution

Answer: (D)

The main idea is the shift from relying on hunting and gathering to producing food through farming and domesticating plants and animals. This change marks a fundamental turn in human societies: people begin to settle in one place, accumulate surplus, and support larger populations. The term Agricultural Revolution fits this moment because it highlights farming as a new system of food production that fundamentally alters how people live. Some sources call this the Neolithic Revolution, but both terms describe the same pivotal transition. The other options refer to later transformations—industrial and scientific—that involve different changes and do not capture the move to agriculture and domestication.
