The correct answer is D) farming.
Farming made the first villages possible.
During the Agriculture Revolution or Neolithic Revolution, humans learned agriculture techniques that allow them to settle in one place. They also started to domesticate animals. For instance, the Sumerians settled between the Euphrates and Tigres Rivers, in the Middle East Region. The flood of the rivers made the land so fertile and humans started to grow crops. This helped in the establishment of the first villages.
