Claim
Making up about one fourth of the continent's surface, it is the second largest drainage basin in South America (after the Amazon basin) and one of the largest in the world.
Correction

The La Plata (Río de la Plata) drainage basin is about 17% of South America’s area (≈3.1 million km²), not “about one fourth.”

Full reasoning
The post claims the Río de la Plata (La Plata) drainage basin makes up **about one fourth** (~25%) of South America. However, a peer‑reviewed study (Physics of the Earth and Planetary Interiors, 2012) describes the basin as about **3,100,000 km²** and explicitly states this is **equivalent to 17% of South America’s area**—well below one fourth. In other words, the basin is closer to **one sixth** than to one fourth. Separately, Encyclopaedia Britannica gives South America’s total area as **17,814,000 km²**; using the basin area (~3.1 million km²) yields ~17–18%, consistent with the paper and inconsistent with “about one fourth.”
