The correct answer is D. The region had soil that was very good for farming. The Fertile Crescent, also known as the "Cradle of Civilization," is a region in the Middle East that stretches from the eastern Mediterranean coast to the Persian Gulf. It is called the Fertile Crescent because it has a curved shape and is made up of fertile land that is well-suited for agriculture. The region has fertile soil, ample water supply from the Tigris and Euphrates rivers, and a climate that is favorable for growing crops. These factors made it an ideal location for the development of agriculture and the rise of early civilizations.
