The correct answer is B) false.
It is false that Sumerian city-states were ruled by councils elected by the citizens.
Sumeria, the oldest civilization known to humans, was not a democracy; Sumerian citizens did not have elections.
Sumerians settled in between the Tigris and Euphrates Rivers in the Middle East, in the territories of what today is Iraq. They founded great city-states such as Kish, Lagash, Ur, or Uruk, but citizens did not choose its rulers.
