问题 Flooding is the most destructive weather disaster in the last hundred years. [br] Wind currents turn out to be more active in colder areas in the northern hemisphere.
选项 A、Y
B、N
C、NG
答案 C
解析 第2个小标题Wind currents部分第1段：Wind currents are generated by the heating activity of the sun．The sun shines more on the area around Earth’s equator than it does on areas farther north and south，causing a heat discrepancy over the surface of the globe．In warmer regions，hot air rises up into the atmosphere，pulling cooler air into the unoccupied space．In cooler regions，cold air sinks，pushing/ driving warmer air into the unoccupied space．The rotation of the Earth breaks this cycle up，so there are several，smaller air-current cycles all along the globe．原文虽然提到了wind currents的成因，及其在warmer regions和cooler regions的活动情况，但并未比较 wind currents在哪个地区更active，故答案为NG。
