Please read the following:
When this happens, a body of warm water that normally pools in the ocean east of Australia begins to move toward the coast of Peru. Warm air rising from the surface of this mass-which is as much as 12F warmer than normal-acts like a paddle stuck into the southern jet stream, redirecting it northward and altering weather from Australia to Canada to Africa. The warm water itself, meanwhile, is like a cap on a bottle when it hits the coast of Peru, halting the rise of cold, nutrient-rich water that typically emerges along the Sough American coast from deep in the Pacific. That drastically affects the food chain for marine mammals, birds, and fish.
When E1 Nino occurs, ___________.
A. it doesn’t change its direction all the way
B. the warm air rising from the sea is much warmer than normal
C. the trade winds in the Pacific blow eastward to the west
D. weather change from Africa to Australia in turn
The key is C. But I think in B “sea” refers to “mass” in the passage so B should be the correct answer. Is that right?
Looking forward to hearing from you.
Thank you in advance.
