Answer:
C. Pastoralism
Explanation:
The Olmec culture flourished along the Gulf Coast of Mexico from around 1200-400 B.C. The Olmecs exercised basic agricultural practices using the slash and burn method in which the whole vegetation is burned and brushing the soil, in order to allow the ash to rest which acts as fertilizers. They opted to setlle near water, because the floodplains were good for agriculture, and it was easier to have fish and shellfish. However, hunting was a major source of food. Deers and domesticated dogs served the requirement of meat.
Trade between native American communities and Europeans began in the 16th century up to the late 19th century. It was important for the creation and maintenance of trade relations with the new colonists. Besides, the native Americans helped the new settlers by teaching them skills needed for cultivating the land as well as hunting. Furthermore, the native cultures benefited from the colonists knowledge of the creation of wealth by means of capital (land), labor and entrepreneurship. In addition, they shared cultural knowledge and learnt the customs from both sides.
