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?

1. Automobile emissions are the largest single source of air pollution.


2. Some of the proceeds from the new tax would go toward expanding the nonpolluting commuter rail system.


3. Currently, the sales tax on new automobiles is considerably lower than 50 percent.


4. Automobiles become less fuel efficient and therefore contribute more to air pollution as they age.


5. The scrapping of automobiles causes insignificant amounts of air pollution.

这道题以前被讨论过，但是没有达成共识。

D or E? I think it should be E because "scrapping" means "exhaust (尾气)"。 选D需要make 太多的assumptions.

我支持选E；理由不多说了。

潜龙勿用

答案应该是D. E怎可能对?

The scrapping of automobiles causes insignificant amounts of air pollution.
