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 recently 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.

I'll go with C. My reasoning:

If C is correct then PZ 1000 is more likely to be involved in an accident than a car from another class. And although the number of injuries per accident for PZ 1000 is low, the percentage of accidents it is involved in is high. Therefore, the number of injuries PER DRIVER-MILE can be high too and that is a good enough reason to believe that PZ 1000 is not the safest car OF ALL

I think it is C.
The next best choice probably is E. If the report is once per annum, the conclusion cannot end 'one of the safest cars available today'

Common weakening scenarios : need help [#permalink] New post 11 Oct 2010, 23:20
While reading through "Weaken question" section in powerscore CR bible , I came across common weakening scenarios. The book mentions that the following scenarios occur most frequently in this type of questions.

1. Incomplete information : The author relies on evidence which is weak and the conclusion can be weakened by bringing in new info.

2.Improper comparison : The author attempts to consider two or more items that are essentially different.

3. Qualified conclusion : The author qualifies or limits the conclusion in such a way as to leave the argument open to attack.

Now , I have come across questions of type 1(Incomplete info) , but i have rarely come across questions of other types . So would you please elaborate the 2nd and the 3rd type with the help of some questions.

OG-verbal review Q24 might qualify under "Incorrect comparison type"

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 recently years many more PZ 1000's 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
54 class is quite pronounced.
(E) The Highway Traffic Safety Institute issues reports only once a year.

In this Ques, PZ1000, which has fewest inj/acci in it's class, is declared as one of the safest cars today. The argument "incorrectly" compares PZ1000 to all cars available today

For the "Qualified conclusion" type, I'm not too sure but Q50 (discussed here) in Verbal review seems like a match.
In this Ques, the author concludes that adequate moisture is essential for crop's survival and will result in prices falling sharply. This conclusion leaves the argument to attack with alternate causes, which may impact the crop's survival.

In D it can go either way. It can go in favour of the argument. Ex if PZ1000 has a ratio of lets say 2 and the other has 5 or vice-versa. In both cases the statement will be true. Hence it can't be the answer. C directly contradicts the conclusion. Hence C.

(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. More accidents means more injuries even if injuries per accident are lower than for other vehicles.
(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. Does not say if the PZ 1000 has more or less injuries per accident than other cars in it's class. The pronounced difference could go either way.

D specifically assumes the difference that may have been present whereas we are bothered more about the # of accidents. Hope that helps

Re: Automobile Dealers Advertisement: The Highway Traffic [#permalink] New post 17 Mar 2014, 04:20
Conclusion of the argument:
The PZ 1000 is one of the safest cars available today.
Premise:
The Highway Traffic Safety Institute reports that the PZ 1000 has the fewest injuries per accident of any car in its class.

There are two assumptions that the author takes while stating the conclusion.
1. The class to which PZ 1000 belongs is the safest among all classes of cars.
2. The number of accidents that happen in PZ 1000 per number of PZ 1000 that run on the roads is substantially lower than any other car.
If either of these two assumptions are shattered we have the right answer.

The statement C attacks the second assumption and states that the PZ 1000 has lots of accidents and hence even though the number of injuries per accident are less but since the number of accidents are more its not really as safe as mentioned.
Hope this explanation helps

Re: Automobile Dealers Advertisement: The Highway Traffic [#permalink] New post 17 Mar 2014, 04:27
The strategy i follow in weaken type of question is that the answer choice must actually destroy the conclusion.( but the facts or premises are respected)

So, here the conclusion is "The PZ 1000 is one of the safest cars available today".

And no other option except C, actually destroys the above mentioned conclusion.

So the answer should be C.

Let me know i make sense

Hi akhil911,

I agree with your second assumption if we remove the word "substantially" from it.

However, I am not very sure about your first assumption. If the first assumption a must be true statement? What if we negate it? What if all other cars (which have the same category as PZ1000) are not very safe? Does that mean PZ 1000 is not the safest car? If none of the Indian cricketers can score more than 10,000 runs, does it mean that Sachin can also not do that?
