112. Older United States automobiles have been identified as contributing disproportionately to global air pollution. The requirement in many jurisdictions that automobiles pass emission-control inspections has had the effect of taking many such automobiles out of service in the United States, as they fail inspection and their owners opt to buy newer automobiles. Thus the burden of pollution such older United States automobiles contribute to the global atmosphere will be gradually reduced over the next decade.
Which one of the following, if true, most seriously weakens the argument?
(A) It is impossible to separate the air of one country or jurisdiction from that of others. Since air currents circle the globe.
(B) When automobiles that are now new become older, they will, because of a design change, cause less air pollution than older automobiles do now.
(C) The number of jurisdictions in the United States requiring automobiles to pass emission-control inspections is no longer increasing.
(D) 原书上缺漏
(E) Even if all the older automobiles in the United States were retired from service, air pollution from United States automobiles could still increase if the total number of automobiles in use should increase significantly.
此题给的答案是C，请问如何分析?不是很明白此题的意思

我看的也比较蒙，大体的感觉是，既然目前旧汽车还是一个污染源，而且是在目前许多地方尾气检查进行的情况下，那么如果目前的检查尾气的状况不变的话，肯定还是解决不了问题。

谁能帮助再分析分析？

增加更多的去掉造成污染的旧汽车的条例，可以减少污染，但C说这类条例并没有增加。

jurisdictions 在这里是什么意思？

Sorry,条例应该改为管辖权

个人意见，仅做参考：

Jurisdiction --- 含义为 ”行政管辖区“。
结合上下文，该题choose“C”

因为如采纳 “ emission-control inspections"的jurisdiction不再增加的话，而已采纳该法的jurisdiction 的效果已满，那就weaken了原文的conclusion。

我觉得E也是削弱，为什么不选E？

结论是：更旧一些的汽车对大气造成的污染将逐步减弱

而如果有关要求汽车进行排放检测的判例数目不再增加（C），那么污染将“逐步减弱”的结论就不能成立。所以C对。

E讲的是笼统意义上的车辆，与题目中说的older automobile是两个概念

我选E,

C中的确提到"逐步减弱", 但还有个"IN NEXT DECADE", 以现在的JURIDICATION淘汰旧汽车, 在这个时间范围内就不能"逐渐减弱"?

而E中的削弱恰恰是针对原文的论证的.

请求大家讨论
