Answer 1

Comprising almost the entire southern half of South America, Argentina is the world's eighth largest country, covering an area of 2.8 million square km. Argentina possesses some of the world's tallest mountains, expansive deserts, and impressive waterfalls, with the diversity of the land ranging from wild, remote areas in southern Patagonia to the bustling metropolis of Buenos Aires in the north. San Luis is West of Buenos Aires
Couldn't find Villa Mercedes or the general involved in the 24 Sept 1874 revolution.
