What was the significance of the annual flooding of the Tigris and Euphrates rivers?

  1. It was predictable and gentle, requiring minimal labor to manage
  2. It was violent and unpredictable, requiring elaborate irrigation systems
  3. It only occurred once every decade or so
  4. It primarily provided saltwater that supported coastal fishing
Show answer and explanation

Correct answer: It was violent and unpredictable, requiring elaborate irrigation systems

Unlike the predictable flooding of the Nile, the Tigris and Euphrates flooded violently and at irregular intervals. This necessitated the creation of complex dikes, canals, and reservoirs, which in turn fostered social organization and centralized government.
