Common people, or workers and farmers, had their homes on the edges of the city. The most important and valued people, such as priests, government leaders, and skilled workers, lived in the center. Also in the center of the city were the buildings that citizens needed access to, such as places of worship and governmental buildings. Some places of worship were also built near the center of the city. What is the central idea of the passage?
