Q28:
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有一點間接關係，但是答案E是什麼意思呢?
scrapping是指刮傷?
還是說目前車子在馬路上飆來飆去不會影響空氣污染。
如果現在該地方的空氣污染都來自工廠，車子本身沒什麼影響，那麼，就算沒有人買車，空氣污染也不會減少阿...?
真奇怪...?

好新人請幫忙看一下吧,thanks.

E的意思應該是

車輛的金屬碎片不會造成顯著的空氣污染

即便不懂SCRAPPING，也可以選出正確答案D
