Which of the following would NOT describe Mississippian Indians?

None apparently.

To determine which of the following options would NOT describe Mississippian Indians, we first need to know what traits or characteristics are associated with Mississippian Indians.

The Mississippian Indians were a Native American culture that existed between approximately 800 CE and 1600 CE in the region now known as the southeastern United States. They were known for their complex societies and large chiefdoms. Based on this information, let's examine each option:

1. Nomadic lifestyle: Mississippian Indians were not known for a nomadic lifestyle. They were primarily agriculturalists, cultivating crops such as maize (corn), beans, and squash. They would settle in semi-permanent or permanent villages where they built mounds and complex structures.

2. Hunting-gathering economy: This option is more likely to describe earlier Native American cultures that preceded the Mississippian Indians. While hunting and gathering were still important for survival, the Mississippian Indians were primarily engaged in agriculture.

3. Regional trade networks: Mississippian Indians were indeed involved in regional trade networks. They had extensive contact and exchange of goods with neighboring Native American tribes and even traded over long distances, as evidenced by the presence of exotic materials like marine shells or copper ornaments.

4. Pueblo-style architecture: Pueblo-style architecture is more associated with Native American cultures in the southwestern United States, such as the Ancestral Puebloans or Hopi. The Mississippian Indians, on the other hand, often built earthen mounds and constructed elaborate wooden structures.

Based on this analysis, option 2, "Hunting-gathering economy," would NOT describe Mississippian Indians, as they were primarily agriculturalists.
