Which set of features is commonly used to define a civilization?

• A. Nomadic lifestyle and hunter-gatherer bands
• B. Urban centers, writing, centralized government, social stratification, and specialized labor
• C. Isolated communities with limited trade
• D. Nomadic pastoralism and absence of writing

Answer: (B)

Civilizations are defined by a level of organized complexity that supports large, settled communities. The set of features that includes urban centers, writing, centralized government, social stratification, and specialized labor captures that complexity. Urban centers bring people, resources, and institutions together; writing allows administration, record-keeping, and coordinated activity across distant communities; a centralized government directs public works, defense, and resource management; social stratification reflects differentiated roles and access to power and resources; specialized labor enables craftsmen, priests, soldiers, and administrators to develop skill and contribute to a growing economy. Together, these elements show a society capable of sustaining large populations and complex institutions rather than wandering as bands or living in isolated, trade-poor communities.

The other descriptions describe patterns more typical of non-civilized or less integrated groups—nomadic hunter-gatherer lifeways, isolated communities with limited trade, or nomadic pastoralism without writing—lacking the permanent cities, written record-keeping, and centralized governance that define civilizations.
