Which assumption about the mound builders is not supported by evidence according to the passage?

• A. They relied on a large labor force for construction
• B. They cultivated a variety of crops
• C. They had ample leisure time for activities
• D. They included specialized craftspeople in their society

Answer: (B)

The choice indicating that the mound builders cultivated a variety of crops is not supported by evidence in the passage because there is insufficient information provided about their agricultural practices. While it is possible that they may have had agricultural activities, specific evidence confirming the cultivation of a diverse array of crops is lacking. The passage may focus more on aspects such as their labor force, leisure time, and the presence of specialized craftspeople, which can be backed by archaeological findings or historical interpretations.

On the other hand, claims about their labor force, leisure activities, and specialized craftspeople likely stem from observations or conclusions made within the study of their society, reflecting a more direct understanding based on archaeological evidence. Hence, option B stands out as the unsupported assumption within the provided context.
