Question Stats:

29% (01:38) correct 71% (00:58) wrong based on 14 sessions
State X spends more money on highway safety and maintenance during the summer months when traffic is heaviest and less during the winter months when traffic is lightest. Therefore, the average number of highway accidents per car should be lower during summer months than during the winter when less money is available for safety and maintenance.

Which of the following, if true, casts the most serious doubt on the conclusion drawn above?


(A) The price of gas rises during the heaviest traffic season.
(B) Traffic congestion significantly increases the likelihood of accidents resulting from road rage or inattention.
(C) Routine road maintenance projects completed during the summer months make roads and highways safer during rain and snow storms year around.
(D) Insurance companies reduce auto insurance premiums if drivers successfully pass safety training courses.
(E) Highway lane lines are repainted every year in state X resulting in safer nighttime driving conditions year around.

Is the OA right?

E seems VERY out of scope.

I would have gone with B

Hi,
In first look, i also pickd B , but after checkign the OA as E, but I think E is correct :

First part of the Arguement implies that in summer maintenance is of high standard than Winter season.
Conclusion states that, it is because of maintenance which cause the Higher Accidents.

To attack the Conclusion, 'E' states that highway Maintenance(Painting) standard is same through out the year. So, accident rates doesnot depends on the Maintenance......

I think you can get something from my explanation...
but i guess its very tricky ... only after knowing OA as E , above reasoning strikd to me...

This is a nice question. Initially I went with B. But C makes more sense as it stresses that the maintenance projects completed in summar make highways safer in winter. Choice B only addresses the likelihood of accidents. It may be the case that likelihood of accidents is more but actual number of accidents in summar is smaller than the one in winter. Hence, choice B does not do a good job of weakening the conclusion.

It should be B, where the only assumption is that heavy traffic leads to congestion.
In C,nothing is being said about the summer months,which is the focus of the argument.

B

C it is. Even with higher spending in summer, winter may have fewer accidents due to the change in conditions

Why did you choose B?

Question asks:
Which of the statement will weaken the conclusion?
It is not talking about the assumption.

Conclusion:
Road accidents should be lower during summer than winters because more money is spent on maintenance during summer.

(C) Routine road maintenance projects completed during the summer months make roads and highways safer during rain and snow storms year around.

This gives us a reason why less money is spent on maintenance during winter. It is not due to lack of funds, as author assumed, but due to the reduced need for repairs during winters, for the maintenance that happens in Summer makes the road good to use throughout the year, including winter and rain.

The road condition is essentially the same in both seasons irrespective of the money spent on repairs during those seasons. Therefore, there is no reason to believe that the accidents will increase during winter.

"C" is a convincing weakener.

B, on the other hands, talks nothing about the correlation between summer/winter, road condition or money spent. It instead talks about completely skewed factors that may cause accidents. Such factors as road rage and inattention should be assumed as constant for both seasons.

Ans: "C"
