Answer:
Humans were nomads. Their wandering was mainly in search of food and shelter. When they found that certain places had an abundance of food – plant food or animals for hunting, they stayed on. They observed the plants, their growth and when these food sources diminished, they grew plants themselves, from the seeds they collected. This is how agriculture came about.
When humans stopped their nomadic ways and stayed together, it paved the way for formation of the human social structure. Hierarchies were established in due course.

Hi, fellow AP Human Geographer. Basically, all that arithmetic density means the total number of people per unit of land area. Having said that, we can immediately eliminate A. because increasing the population would only increase the total number of ppl. per unit of land area. Next, B. B can work, theoretically; however, there is a better answer. Next, D. D. says limiting the number of farmers; while this will technically reduce the number of ppl. per unit of land area, again there is a better answer. Next, E. I'd say this is the toughest choice; however, by increasing the area of urban areas, it can end up attracting more people instead. Overall, the best answer would be C., limiting the size of the population.
