※ 引述《chenemily (天天保持好心情)》之銘言：
: 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.
: 請問 這題 我列出來的因果是
: the fewest injuries per accident ----> one of the safest cars
: ABDE 我都知道攻擊點在哪
: 但是整解C 題目不是已經說 PZ1000 has the fewest injuries
: 可是C又說 more likely to be involved in accidents 這樣不就矛盾了
: 是哪邊想錯了嗎
: 麻煩一下
fewest injuries "per accident"
要注意 GMAT CR 很常在 Percent 和 Number 的區別當作考點
injuries 平均數低 不代表總數低
C 的意思就是在說 injuries 平均雖然低 但 accidents 多
所以 injuries 總數就有可能會比較高
