2. describe the social structure that developed in the olmec civilization and how they depended on each other

The social structure of Olmec consists of two groups: the main population, or common people we can say, and the elite. The common people used to work on the farms or with the watering or the irrigation systems in rural areas, providing food for the population which the elite lived apart of.
