GENERAL KNOWLEDGE

Detailed explanation-1: -As these early farmers became better at cultivating food, they may have produced surplus seeds and crops that required storage. This would have both spurred population growth because of more consistent food availability and required a more settled way of life with the need to store seeds and tend crops.

Detailed explanation-2: -By actively managing their food supplies, agricultural societies were able to produce more food than hunter-foragers and support denser populations. Having a large population nearby made it worthwhile for farmers to grow more food than they needed for themselves, as they could trade this surplus for other goods.

Detailed explanation-3: -Agriculture allowed people to stay in one place, and increased food production caused the population density to expand far beyond levels that could be sustained by hunting and gathering alone. This growth in population density provided a critical mass of people to sustain and spread contagious infectious diseases.
