Which is the most important river system of Australia?
- A.Murray-Darling
- B.Mackenzie
- C.Orinoco
- D.Parana
Correct answer
Explanation
The correct answer is A, Murray-Darling. The Murray rises in the Snowy Mountains of the Great Dividing Range and, with its long tributary the Darling, drains the south-eastern interior of Australia; the basin is the country's chief farming region for wheat, fruit and sheep, and it is supported by the Snowy Mountains water scheme and by the wells of the Great Artesian Basin. Option B, the Mackenzie, is the longest river of Canada and flows to the Arctic Ocean, so it belongs to North America. Option C, the Orinoco, drains the Llanos grassland of Venezuela and Colombia in South America. Option D, the Parana, is the great river of Brazil, Paraguay and Argentina on which the Itaipu dam stands and which ends in the Rio de la Plata estuary.
