Scientists have learned about the ancestral pueblo mostly by studying? a oral history b written records c mounds d housing and artifacts

The correct answer is D) housing and artifacts.

The Ancestral Puebloans were an ancient Native American culture that occupied Colorado, Utah, Arizona and New Mexico. Remains found by archaeologists suggest they had knowledge on pottery, knitting and irrigation. They also created many pictographs and petroglyphs. Artifacts such as cliff houses, rock art and systems of roads helped historians learn more about Ancestral Pueblo.
