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.
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不明白A为什么不对?
A不对 A反对前提 前提说了 PZ 1000 has the fewest injuries per accident 答案是C 注意per accident =事故数除以总数 C说PZ1000发生事故的总数多 所以分母大 两个一除才会小 削弱 他因 愚见希望对你有帮助
明白了，多谢你！
