Answer:
Because they buried their dead in large mounds
Explanation:
Mound Builders were prehistoric American Indians, named for their practice of burying their dead in large mounds. Beginning about three thousand years ago, they built extensive earthworks from the Great Lakes down through the Mississippi River Valley and into the Gulf of Mexico region.
In the picture/model shown, this can be used as evidence to argue that the Egyptians did live in settled communities. This picture shows that a person was planting fields and that he would be doing so for more than himself. He was most likely one of hundreds of plowmen used to plow the fields.
