Which term describes theories that claim all societies progress identically?

• A. Unilinear
• B. Multilinear
• C. Cyclical
• D. Postindustrial

Answer: (A)

The main idea being tested is how early theories of social development described human societies. Unilinear theories claim that all societies progress along the same universal path, moving through identical stages from simple to more complex forms. In other words, every culture would develop in the same sequence, regardless of environment or history. That makes unilinear the best description for theories claiming identical progression across all societies.

In contrast, multilinear theories argue that societies can follow different developmental paths based on local conditions; cyclical ideas emphasize recurring rise-and-fall patterns rather than the same fixed sequence for everyone; and postindustrial refers to a later stage in industrialized societies, not a universal progression applicable to all cultures.
