Answer:
A. The Anasazi moved south where more water was available.
Step-by-step explanation:
The Anasazi people lived on the Four Corners region, a location where rain is scarce and irregular. To adapt to this mountain location, the Anasazi people used to migrate to other areas, looking for water. On the other hand, these people have progressively adapted irrigation techniques from Mexico, either extracting water from rivers or rainwater reservoirs. They built small dams, channels and reservoirs that prove a community organization.
