Which two regions in Argentina do not lie 600 meters or more above sea level?

The correct answer identifies Rio Negro and Neuquen as the two regions in Argentina that do not lie at elevations of 600 meters or more above sea level. Both of these regions, located in Patagonia, are generally characterized by lower elevation compared to other Argentine wine regions.

In contrast, Mendoza, although it has some lower areas, is well-known for its high-altitude vineyards, particularly in places like Luján de Cuyo and the Uco Valley, which frequently exceed 600 meters. San Juan, while it has some lower lying areas as well, also contains significant sections of vineyards that are above this altitude.

Salta is renowned for having some of the highest vineyards in the world, often well above 600 meters, particularly in the Cafayate area. Catamarca, as well, features high-elevation regions that contribute to the production of high-quality wines.

La Rioja in northern Argentina features vineyards at elevations exceeding 600 meters, particularly in the areas aligned with the Andes. Buenos Aires, being more urban and not a major wine-producing region, also features vineyards that are generally at lower elevations, but does not outproduce the regions of Rio Negro and Neuquen that are consistently lower in altitude throughout.

This context sufficiently clarifies the correct choice
