GENERAL KNOWLEDGE

Detailed explanation-1: -Farming probably involved more work than hunting and gathering, but it is thought to have provided 10 to 100 times more calories per acre. More abundant food supplies could support denser populations, and farming tied people to their land.

Detailed explanation-2: -Rather than having to comb through the landscape for food, people could now grow as much as they needed and where they needed it, so they could live together in larger groups. As the population quickly increased, ideas could be more readily exchanged, and rates of technological and social innovation soared.

Detailed explanation-3: -Agriculture brought about important changes. Man gave up his nomadic life and settled down at one place in selected areas. He could grow his own food. He no longer was a wanderer or gatherer and settled down in one place.

Detailed explanation-4: -Agriculture freed humans from the natural productivity of the territory they occupied and allowed them to manipulate their environment to meet their needs. This in turn allowed them expand their communities and meant they had to spend less time in the pursuit of food, freeing them to do other things.
