Buenos Aires and Montevideo are situated across the banks of
- A.River Plate
- B.Orinoco River
- C.Purus River
- D.Madeira River
Correct answer
Explanation
The correct answer is A, River Plate. Buenos Aires, capital of Argentina, and Montevideo, capital of Uruguay, face each other across the Río de la Plata.
The River Plate is a wide funnel-shaped estuary formed where the Paraná and Uruguay rivers meet before entering the Atlantic Ocean. Buenos Aires stands on its southern bank and Montevideo on its northern bank, making them two of the world's closest pairs of national capitals. The estuary widens to about 220 km at its mouth. It is also remembered for the Battle of the River Plate in 1939, the first major naval battle of the Second World War.
B is wrong because the Orinoco flows through Venezuela and Colombia into the Atlantic in the north of the continent. C is wrong because the Purus is a tributary of the Amazon flowing through Peru and Brazil. D is wrong because the Madeira is another large Amazon tributary, flowing from Bolivia into Brazil, far from these two capitals.
Exam tip: Río de la Plata = Paraná + Uruguay estuary; Buenos Aires (south bank) faces Montevideo (north bank).
