How did the development of agriculture bring change to human society?

The answer is:

People learned how to plant their own seeds to produce food. They no longer had to follow animal herds and were able to settle in one spot for an extended period of time.

Hope that helps :)

the fact that could also be added to column b is that during world war ii, specifically between the years 1941 and 1945, japan expanded its territory towards the indonesian territory in what was known later as part of the "pacific war". in that time, japan could conquer the philipines, singapore,   borneo, central java, malang, cebu, sumatra and various other islands of the area, therefore expanding its territory for a brief period of time.
