Which of the following was NOT a social class in Sumer?

The correct answer is "Noble warriors" because in Sumerian society, the social classes were typically categorized into distinct groups such as elites, dependent commoners, and free commoners. The Sumerians had a rigid class structure, with the elites being the ruling class and priests, while commoners were divided into dependent and free categories based on their wealth and status.

Dependent commoners were those who worked the land owned by the elites and were often tied to their lords through obligations, while free commoners had more autonomy and could own land or businesses. The concept of "noble warriors" does not accurately reflect the Sumerian social hierarchy, as military roles were generally integrated within the elite class rather than constituting a separate class of "noble warriors." Sumerians viewed the warrior aspect as part of their elite function, primarily associated with maintaining power and order rather than establishing a distinct social class of nobility based on warrior status.
