Task: Question Generation
Input (English): Cultural practices in the Americas seem to have been shared mostly within geographical zones where unrelated peoples adopted similar technologies and social organizations. An example of such a cultural area is Mesoamerica, where millennia of coexistence and shared development among the peoples of the region produced a fairly homogeneous culture with complex agricultural and social patterns. Another well-known example is the North American plains where until the 19th century several peoples shared the traits of nomadic hunter-gatherers based primarily on buffalo hunting.
Output (English): What creature did the nomadic hunter-gatherers of the plains hunt?
