Answer:
Most of the population of South America lives in the middle latitudes because the southernmost part of the continent, which belongs to Argentina and Chile, is one of the coldest places on Earth. This place, called Patagonia, is a mountainous region, with lots of rivers and lakes, and some valleys in which small cities are located (for example Bariloche, Neuquen, Comodoro Rivadavia, Rio Gallegos and Ushuaia in Argentina, and Punta Arenas in Chile).
