Final answer:
A river valley, particularly the Fertile Crescent, was the most favorable location for agriculture.
Step-by-step explanation:
The most favorable location for growing crops and raising livestock is A River Valley. In particular, the fertile river valleys like the Fertile Crescent, which includes regions in Mesopotamia and southern Turkey, enjoyed significant advantages for agriculture. These areas had nutritious staple crops like wheat and barley, as well as native animal species like goats, sheep, and cows. The temperate and fertile conditions in river valleys allowed for the transition from hunting and gathering to large-scale farming.
