CLEP Western Civ I

Answer: B - Most early Mesopotamian civilizations existed as city-states, a geopolitical structure in which each city governed itself independently of neighboring communities even though they were part of the same larger civilization. Though most Mesopotamian city-states were ruled by kings, they did not operate politically as monarchies. The city-state power structure was common in the classical world as well, before empiricism became the common method of rule.
