Question

The length of time hunter-gatherers stayed in one region depended on _____.

climate conditions
other nomadic people
available food
amount of stored food
soil fertility

Answer 1

I'd say available food, or the third option. The hunter-gatherers were people who would travel solely on the basis for the food, so when they would run out of food in a specific area they would pack up and move to the next. I hope this helps :)
