Automobile Dealer's Advertisement:

The Highway Traffic Safety Institute reports that the PZ 1000 has the fewest injuries per accident of any car in its class.  This shows that the PZ 1000 is one of the safest cars available today.

Which of the following, if true, most seriously weakens the argument in the advertisement?

(A) The Highway Traffic Safety Institute report listed many cars in other classes that had more injuries per accident than did the PZ 1000.
(B) In recent years many more PZ 1000s have been sold than have any other kind of car in its class.
(C) Cars in the class to which the PZ 1000 belongs are more likely to be involved in accidents than are other types of cars.
(D) The difference between the number of injuries per accident for the PZ 1000 and that for other cars in its class is quite pronounced.
(E) The Highway Traffic Safety Institute issues reports only once a year.

答案选C
能解释下为什么选C吗？谢谢！！！

题目的论点是该车是＂所有车中＂最安全的，但是报告只说它是本级别内最安全的。但是它的这个级别按照c的内容来说是比其他级别更危险的。想夸张一点，最安全的拖拉机级的车绝对没有一般的豪华型轿车安全。

fewest injuries per accident不等于车子安全 因为可以是accidents很多 如此一来 分母变大 最后所得的injuries per accident就小 C正确
