Need to stockpile and protect crops
Answer:
Need to stockpile and protect crops.
Explanation:
As the agricultural revolution progressed, there was a need for more sophisticated organization. Higher levels of production led to a surplus, and communities had to come up with ways in which this surplus could be stored and protected efficiently. The need for organization led to a higher division of labor, and the sophistication and specialization of the work in turn led to the formation of social hierarchies.
