Which of the following commodities is commonly associated with the Puna region?

The Puna region, characterized by its high altitude and unique ecological conditions, is best known for raising livestock, particularly sheep. This region, primarily located in the Andean highlands of South America, features a climate and terrain that are well-suited for pastoral activities rather than intensive agriculture. Sheep farming is integral to the culture and economy of the Puna, providing wool and meat for local communities.

While coffee, wheat, and copper are important commodities in various regions, they do not have the same strong association with the Puna. Coffee typically thrives in lower, more humid elevations, wheat is usually cultivated in areas with more temperate climates, and copper mining occurs in specific geological formations rather than the high-altitude Puna environment. Therefore, the prominence of sheep herding in the Puna makes it the most accurate choice among the commodities listed.
