Based on the description provided, the Mound Builders primarily lived in regions that extend from the Great Lakes to the Gulf of Mexico and from east of the Mississippi River to the Appalachian Mountains. Without seeing the specific map, I can suggest that the appropriate regions would likely be those that fall within these geographical boundaries.
Typically, you would choose the regions that encompass:
- The area around the Great Lakes.
- The area around the Mississippi River down to the Gulf of Mexico.
If the map's regions correspond to these areas (often labeled as Region A or Region B, etc.), select those corresponding regions. If you could provide details about what each region represents, I would be better able to guide you in selecting the correct answers.
