Which of the following correctly describes the pampas in Argentina and Uruguay?

The pampas are vast, flat, and fertile grasslands located primarily in Argentina and Uruguay. These temperate grasslands are characterized by their rich soil and moderate climate, which support a diverse range of plant and animal life, making them ideal for agriculture and livestock farming, particularly cattle ranching. The ecosystem of the pampas is pivotal to the agricultural economy of these countries, contributing significantly to their overall productivity. The correct answer highlights the defining geographical and ecological characteristics of the pampas, distinguishing them from other options that do not accurately represent this specific landscape. Migrant workers, jagged peaks, and wild horses pertain to different concepts or geographical features that do not encapsulate the essence of the pampas as temperate grasslands.
