Certain politicians in the country of Birangi argue that a 50 percent tax on new automobiles would halt the rapid increase of automobiles on Birangi’s roads and thereby slow the deterioration of Birangi’s air quality. Although most experts agree that such a tax would result in fewer Birangians buying new vehicles and gradually reduce the number of automobiles on Birangi’s roads, they contend that it would have little impact on Birangi’s air-quality problem.
Which of the following, if true in Birangi, would most strongly support the experts’ contention about the effect of the proposed automobile tax on Birangi’s air-quality problem?
A. Automobile emissions are the largest single source of air pollution.
B. Some of the proceeds from the new tax would go toward expanding the nonpolluting commuter rail system.
C. Currently, the sales tax on new tax on new automobiles is considerably lower than 50 percent.
D. Automobiles become less fuel efficient and therefore contribute more to air pollution as they age.
E. The scrapping of automobiles causes insignificant amounts of air pollution.
A说汽车排放是空气污染最大的来源，除非你预测，说最大的来源一定会导致较多的空气污染，否则来源是否是最大的原文没说，杀。B说收的税会用于扩大一些没有污染的有轨电车，这个选项说的是收上来的税干什么用，原文没提，杀。C说销售税低于50%，原文说将要收50%，和现在收多少有什么关系？杀。D说当一些车老化后导致更多的污染，说的是导致污染，留着。E说汽车导致污染量不大，好像也沾点，留着。看问题，问题问的是支持原文那个预测，就是预测收税不会减少空气污染，D感觉是当我老化的时候会怎么样（有点像预测的味道），E说我现在导致污染程度不高（陈述现状），那个和那个预测连上点？显然是D。
