The Fertile Crescent (also known as the "cradle of civilization") is a crescent-shaped region where agriculture and early human civilizations like the Sumer and Ancient Egypt flourished due to inundations from the surrounding Nile, Euphrates and Tigris rivers.
"The Fertile Crescent produced many good crops; some would say the best place to find farmland in the Fertile Crescent was near the jutted out land in between two rivers: the Tigris and Euphrates." Although that sentence is more of a fact, it is still a sentence. Hope it helped :)
