Final answer:
The primary advantage of crop farming during the Agricultural Revolution was a more reliable food supply, which led to improved yield from crops, increased specialization of labor, and the rise of complex societies.
Step-by-step explanation:
During the Agricultural Revolution, the main advantage of crop farming over traditional hunter-gatherer societies was b. a more reliable food supply. The shift to agriculture allowed for an improved yield from crops, leading to an excess of food that could be stored and traded. This surplus facilitated the development of new jobs, technologies, and economies, as not everyone needed to participate directly in food production. Additionally, domestication of plants and animals contributed to increased nutritional qualities of food crops and provided a consistent, stable food source. Overall, the transition to settled farming practices was pivotal in allowing for increased specialization of labor and the rise of more complex societies.
