下面试GMAT逻辑题目(342):

　　Automobile Dealer's Advertisement:

　　The Highway Traffic Safety Institute reports that the PZ1000 has the fewest injuries per accident of any car in its class. This shows that the PZ 1000 is one of thesafest cars available today.

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

　　(A) The Highway Traffic Safety Institute report listedmany cars in other classes that had more injuries per accident than did the PZ1000.

　　(D) The difference between the number of injuries peraccident for the PZ 1000 and that for other cars in its class is quitepronounced.

　　(E) The Highway Traffic Safety Institute issues reportsonly once a year.

　　GMAT逻辑答案:

　　参考答案: C

　　思路：A. 加强了结论;

　　B：如果PZ1000卖的比别的车多，然而事故率还低，加强说它是最安全的;这里的范围扩大词anyother是可以的。因为文中提到了anycar, 所以并没有范围扩大。但此选项意思不对。

　　D：加强说PZ1000的事故率比别人低很多;

　　E：完全无关。

　　C: PZ1000虽然在它的class属于最安全的，但是它的class中的车比起别的class中的车，却更危险，所以PZ1000比起其它车不一定最安全。正确选项。此选项中的比较对象other types of cars在文中出现过，不是无关比较。
