Certain politicians in the country of Birangi argue that a 50 percent tax on new automobiles would halt the rapid increase of automobiles on irangi’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.
answer: D
答案D有一点间接关系，但是答案E是什么意思呢?
scrapping是指刮伤?
还是说目前车子在马路上飙来飙去不会影响空气污染。
如果现在该地方的空气污染都来自工厂，车子本身没什么影响，那么，就算没有人买车，空气污染也不会减少阿...?
真奇怪...?
好心人请帮忙看一下吧,thanks.
同意！
