Conclusion:
according to argument we could reduce the number of accidents by increasing the use of 3 trailer trucks and reducing the use 1 and 2 trailers truck .

If we could prove that we can reduce the number of accidents by method other than mentioned in the conclusion, Then that would be the answer choice.

Choice B correctly states that we can reduce the number of accidents by hiring experienced drivers for 1 and 2 trailers truck also

Correct B
Type: weaken

Conclusion: increase the use of triple truck => reduce death

Assumption: increase triple truck is the only cause.

Break the assumption: there are other cause that could reduce death. namely: driving experience of the driver is the main cause.

Hence choice B is the correct one

so far only the best, most experienced drivers for Patorian trucking companies have been driving triple trailer trucks.

The answer is B. the argument fosters a link between the accident rate and the skills of a driver. Incresing the number of large trucks will decrease the number of "best drivers" carrying it to depletion. Employing ordinary drivers might rise the accident rate, regardless of the truck type.

This question appeared as the first question Verbal section of my GMAT Prep Test 1 , and I got it wrong. Option B looked good to me but option E appealed more.
Can somebody, experts, please explain why option E is incorrect? If the payload of the largest trucks is less , doesn't it mean that they are less prone to accidents than smaller trucks which in addition to being small are carrying more loads?


To answer your question:
No. The text does not say anything like that, yours is an additional assumption.

We want to weaken that "one way for partoria to reduce highway deaths would be to reduce shippers to increase their use of triple trucks."

E talks about the maximum payload
E. In patoria, the maximum legal payload of a trailer truck is less than three times the maximum legal payload of the largest of the single trailer trucks.
that is nowhere mentioned in the passage, so we cannot infer that is connected somehow to the incidents.

B on the other hand says that
B. so far only the best, most experienced drivers for Patorian trucking companies have been driving triple trailer trucks.
so the data on which the conclusion is based ("The very largest trucks those with three trailers had less than a third of the accident rate of single and double trailer trucks.") is not reliable, so the whole argument is weakened.

Hope it's clear



Hi Zarrolou

I have a doubt here regarding option E
As it is stated that we need to increase Trucks with triple trailer in order to reduce accident rate

So as per my understanding E states that payload for triple trailer is less than single or double, now due to this reason transporter would not choose triple trailer in comparison to others .Hence weakening the conclusion

Kindly correct me if wrong

It's because there is nowhere mentioned in the passage that relates the weight of payload to accidents.

There is a variation to this question. saw it posted by GWD

In the nation of Partoria, large trucks currently account for 6 percent of miles driven on Partoria’s roads but are involved in 12 percent of all highway fatalities. The very largest trucks—those with three trailers—had less than a third of the accident rate of single-and double-trailer trucks. Clearly, therefore, one way for Partoria to reduce highway deaths would be to require shippers to increase their use of triple-trailer trucks.
Which of the following, if true, most seriously weakens the argument?
A. Partorian trucking companies have so far used triple-trailer trucks on lightly traveled sections of major highways only.
B. No matter what changes Partoria makes in the regulation of trucking, it will have to keep some smaller roads off-limits to all large trucks.
C. Very few fatal collisions involving trucks in Partoria are collisions between two trucks.
D. In Partoria, the safety record of the trucking industry as a whole has improved slightly over the past ten years.
E. In Partoria, the maximum legal payload of a triple-trailer truck is less than three times the maximum legal payload of the largest of the single-trailer trucks

B
Three-trailer trucks are driven by the most experienced drivers. If use of three-trailer trucks is required, that would mean less-experienced drivers on the roads, therefore more accidents, which is what Partoria is trying to reduce.

Hi,

E. In patoria, the maximum legal payload of a trailer truck is less than three times the maximum legal payload of the largest of the single trailer trucks.
Which trailer truck we are referring to in the option E?

Thanks :-)

let us break the argument down -

Premise
Large trucks - 6% of the miles driven BUT 12% of fatalities. (Seems to imply that trucks are more dangerous than other types of vehicles).
three trailer trucks have 1/3rd fatality rate of other large trucks

Conclusion
Use triple trailer trucks --> Reduce accidents

We have been asked to weaken the conclusion, i.e. to point out that this proposal may not lead to the conclusion - Reduce accidents.

A - Incorrect.
The objective here is to reduce fatalities caused by other large trucks by replacing them with triple trailer trucks. Since those roads are anyways not accessible to other large trucks also, this point is irrelevant.
If the accident rates on other roads are reduced, that would lead us to the conclusion - Reduce accidents.

"some smaller roads off limits" - the word "some" is vague. What if only 0.1% of the roads are off limits? Then this issue has no statistical significance on the argument.

B - correct answer.
this weakens the conclusion by giving an Alternate Cause for the premise that -
triple trailer trucks are safe --> hence, 1//3rd accident rate

this gives us reason to believe that triple trailer trucks themselves may not be safe, but the lower fatality rate is due to better drivers.
If this is the case, we can say that using more of triple trailer trucks will NOT necessarily reduce fatalities on the road.

C - incorrect.
Still, this answer option does not change the fact that 12% of fatalities are from trucks. Those accidents may be between trucks and other vehicles then (since the truck to truck number is low)

D - Incorrect.
Does not mean that the conclusion -
"One way to reduce accidents is to use triple trailer trucks" is untrue.

E - Incorrect.
it should read "maximum legal payload of triple trailer trucks"

We have no idea how "legal payload" relates to "accident rates" or whether these limits are imposed or followed.
Hence, irrelevant.

Thanks for quick response, sudeep. I strongly agree with you that only (B) is relevant to the argument. However, I don't feel that this option weaken the argument obviously. So, would you please give me more explanations?


My reasoning:

Trailers types :

1 trailer
2 trailer
(largest) 3 trailer - fewer accidents than others

What could be the reason - largest are better option for transportation, the drivers that drive largest trucks are better(actually best among the drivers), or they drive on the routes which are less vulnerable to accidents. There could be more reasons but I just picked 3 and the last one, referring to route, is also not relevant as it is neither discussed in the passage nor given as an option.

Passage picked the first reason. How can it be weakened? Only if we can prove that other reason was there and not the one picked.

So, B points to the second reason.


Sudeep dont you think option B is instead strengthening the argument?
The argument tells largest trucks must be used more to reduce accidents but this needs to be weakened. However, option B states that largest trucks have the best drivers so i feel this statement strengthens the argument instead. Please tell me where am i going wrong?
