Answer:
A) The Mississippian people lived in a region with a wet climate, whereas the Ancestral Puebloans lived in a dry climate.
Step-by-step explanation:
The Mississippian people lived in an environment that supported a variety of crops and allowed them to develop large communities. The Ancestral Puebloans lived in a dry environment that kept villages relatively small and they built irrigation systems to carry water to their farms so they could grow crops in the desert.
