Answer: B) Development of farming methods and domestication of crops and animals enabled a reduction in dependence on hunting and gathering for food; greater dependence on agriculture reduced the need to follow herds of wild game.
Explanation;
A Sedentary lifestyle refers to one that does not have to do with a lot of moving around which would mean that the American Indians described were substantially non-nomadic people which meant that they did not migrate to follow food sources like wild game.
They were also described as being more reliant upon the cultivation of the soil for subsistence which means that they depended on Agriculture for food instead of hunting and gathering. This was probably due to improvements in farming methods as well as the domestication of animals and crop species.
