Answer: "Southern Grassland Countries" often refers to those countries in southern South America, especially the Pampas region, that are renowned for having vast grasslands. One of the important nations in this region is Argentina.
Explanation: Thus, among the choices listed:
- Argentina: The Southern Grassland Countries do include Argentina. Part of South America's Southern Cone, a territory renowned for its agricultural pursuits, the Pampas region of Argentina is well-known for its expansive grasslands.
- Bolivia: The Southern Grassland Countries do not include Bolivia. Rather of being made up of huge grasslands, it is situated in western South America and has a varied topography that includes the Andes Mountains, the Amazon rainforest, and the Altiplano.
- Gambia: The country of Gambia does not belong to the Southern Grasslands. The Gambia is not in South America; rather, it is a small nation in West Africa.
- Guiana: Likewise not included in the Southern Grassland Countries is Guiana, sometimes known as Guyana. Although Guyana is a country in northeastern South America with a varied terrain that includes savannas and rainforests, it is not commonly connected to the vast grasslands of the Southern Cone.
In conclusion, of the nations listed, Argentina is the only one that belongs to the Southern Grassland Countries, which are distinguished by their vast grasslands in the Pampas region. The other nations listed do not belong to this particular geographic region.
