The First Agricultural Revolution is characterized by

• A. Dating back 10,000 years, plant domestication and animal domestication
• B. The use of GMOs and pesticides
• C. The invention of tractors and mechanized farming
• D. The global distribution of crops

Answer: (A)

The main idea here is the shift from hunting and gathering to farming, specifically the domestication of plants and animals that makes permanent settlements possible. This change began around 10,000 years ago in various regions and is known as the Neolithic Revolution. The ability to cultivate crops and raise tame animals created reliable food supplies, which supported larger populations and the development of villages and eventually more complex societies.

The other options point to later developments in agriculture. GMOs and pesticides are products of modern agricultural science, not the first shift to farming. Tractors and mechanized farming belong to the industrial era of agriculture, well after the initial transition. Global distribution of crops reflects later diffusion and trade, not the original domestication and settlement that define the first agricultural revolution.
