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C 怎么看怎么加强.... 买pz1000的那些家伙更容易出车祸... 但是pz1000却奇迹的让他们获得了最少的受伤比率... 加强阿

我选E 说明了他的report现在不准啦~~ 一年里没准就有更牛的车被制造出来了...

恩~~ 指点一下~~ 谢谢谢谢！！！！！

Situation:　Ｐ在它的级别的车里是最少发生事故的．所以说Ｐ是现今最安全的车．

（这个题的assumption明显是说Ｐ所在的级别是所有车的级别中最安全的，那么它才能成为所有车中最安全的）

Ｃ项，正好与这个assumption相反．

E是无关项.报告发布的频率与这有何关系?--题说的是P所在车的级别和其他车的关系.(LZ说的什么一年更牛的车什么的,都是你自己想的,E项里根本没说!)

个人意见，原文认为p是每次事故中受伤最少的车，并没有说p车发生事故的概率

而c说p车是出事故最多的，所以weaken

简单说：虽然同类车中他最牛，但是由于整个类别差，所以不能说P车是所有车中就牛了。所以C是weaken。

周末愉快

我的理解是,

P车是同类车里比较安全的车,但是P所belong的这类车比其他的车类更加容易发生事故.所以P其实也是事故多发车.

所以WEAKEN.

因为P在同类车中最安全，所以P是世界上最安全的车。
C：P所在的类别是最不安全的，所以不能推出P 是世界上所有类别中最安全的。同一个公司竞争出最好的怎么能说明在所有公司中是最好的呢？刚好所在的公司在全球排名最差就更不能说明这个公司是全球最好的了。
