Answer:
4) 10,000 years ago
Step-by-step explanation:
The Agricultural Revolution, also known as the Neolithic Revolution, was a significant period in human history when hunter-gatherers transitioned from nomadic lifestyles to agricultural settlements. It is thought to have begun roughly 10,000 years ago in an area within the Middle East called the Fertile Crescent. A possible cause of this sudden shift was the rise of environmental changes. Wild crops such as barley and wheat began to grow as a result of the warmer weather, which also provided a suitable climate for farming practices. Some scientists also argue that the Agricultural Revolution began as a result of intellectual advances in the human brain because of artifacts and artistic imagery found at early settlements.
