In recent years the climate has been generally cool in northern Asia. But during periods when the average daily temperature and humidity in northern Asia were slightly higher than their normal levels the yields of most crops grown there increased significantly. In the next century, the increased average daily temperature and humidity attained during those periods are expected to become the norm. Yet scientists predict that the yearly yields of most of the region’ s crops will decrease during the next century. Which one of the following, if true, most helps to resolve the apparent paradox in the information above?
选项
A、Crop yields in southern Asia are expected to remain constant even after the average daily temperature and humidity there increase from recent levels.
B、Any increases in temperature and humidity would be accompanied by higher levels of atmospheric carbon dioxide, which is vital to plant respiration.
C、The climate in northern Asia has generally been too cool and dry in recent years for populations of many crop insect pests to become established.
D、In many parts of Asia, the increased annual precipitation that would result from warmer and wetter climates would cause most edible plant species to flourish.
E、The recent climate of northern Asia prevents many crops from being farmed there during the winter.
答案
C
解析
要解释分歧,就要找差异原因,(C)通过找他因的办法解决了上述分歧,为正确答案。最近几年,在气温和湿度较高的那一段时间内,庄稼产量显著升高是因为这几年气候普遍比较干燥,庄稼害虫不能大规模生长;下个世纪,虽然气温和湿度普遍较高有利于庄稼生长,但同时也有利于庄稼害虫大规模生长,因此产量会下降。
