Answer: please mark as brainliest
if they farmed then the answer would be A but if they didn't farm then the answer would be hunting and i'm pretty sure it is hunting.
Explanation:
Hunter-Gatherers
These people, who depended on meat to live, followed herds of animals. They could not afford to stay in one place for very long. For a period of time, they might live on a grassy plain, then when the animals migrated to the mountains, the hunter-gatherers followed. If they didn't, they would starve.
They also had to be able to adapt to changes in climate and geography. For the hunter-gatherers, any environment was home. They had to overcome the hardships of changing geography, therefore, staying in one place like the farmer was not possible. They had to be ready to adapt to every situation, and they did so by adopting a nomadic lifestyle.
Agrarian Societies
As they traveled from place to place, some hunter-gatherers found plains with rivers nearby. Here, there was plenty of game, they also found many plants that could be used for food. Rather than continuing to move from one area to another, they settled down. Before long, plants such as wheat, barley, and different roots became their main source of food. Once they learned to cultivate the soil and domesticate animals, there was no longer a reason to move on.
For them, areas with a lot of trees, rocky soil, or little water were not good places to live, so, if they had to move, they looked for land where they could grow crops. That is why places such as Mesopotamia, the Nile River Valley, and the Indus Valley were good for them. The climate was ideal, with plenty of rain and water. Whenever the river overflowed, it left rich soil behind. Finally, they did not have to worry about the food supply as much because food was growing out of the ground all around them.
As time passed, groups of people farmed in the same area, and small towns were born. They learned to harness the water with irrigation and wells which allowed them to get water from the river in times of drought.
