Which of the following did not contribute to the collapse of Mesopotamian civilization?
rising water table
seasonal irrigation
poor drainage of irrigated fields
large population

Seasonal irrigation was actually a critical factor that supported agriculture in Mesopotamia rather than contributing to its collapse. By managing water from the Tigris and Euphrates Rivers, societies could grow crops reliably, allowing civilizations to flourish for centuries. They cleverly devised a calendar to predict the flooding seasons, creating a robust agricultural economy.

On the other hand, a rising water table and poor drainage created salinization issues, damaging crops and diminishing food resources. As the large population grew, demands on the land intensified, making these agricultural problems even more severe. So while seasonal irrigation was a boon, the other factors posed significant threats to sustainability!
