To solve the traffic congestion problem of the 60 km long north-south link road, the municipal corporation has decided to build a parallel road for the middle stretch of 50 km of the north-south link road. The administration hopes to recover the money spent on this project by charging a toll of Rs. 50 for the first year after the completion of this new road. They estimate the traffic to become evenly distributed between the two roads only after this initial year.

Which of the following, if true, most weakens the conclusion?

A. The north-south link road connects two different parts of the city and will always be more in demand and more congested than will any other existing road.
B. The cost of building the new road will not be covered by the charging the decided toll rates for a year.
C. Most of the traffic on the north-south link road is due to office going people who do not mind paying up for a traffic-free ride to work.
D. The construction of the new road will not be completed for at least three years.
E. The north-south link road already has three parallel roads of 5 km each in different areas along its length.

Isnt option A correct

Explanation:
Conclusion says that the traffic will be evenly distributed once the road is built & do not say anything about the cost.

Option C says that commuters are willing to pay 50rs as toll. how will that weaken the conclusion.

Please explain.

From what i could infer , the argument concludes that the traffic will evenly distribute only after the initial year. now , if the office people are willing to pay the toll for the traffic free road , the trafiic would be distributed before the completion of the intial year.
Please correct me if I'm wrong

C is correct. These drivers are willing to pay for traffic-free rides, but another new road, though charges money, will not be traffic-free as result.

At first some drivers may move to this new road, while later more and more drivers move to this new road. They will therefore find this road NOT TRAFFIC-FREE. Eventually, some may move back to the original road.

So based on C, we CANNOT say: evenly distributed between the two roads only after this initial year.

Yes this is what I think: At first some drivers may move to this new road, while later more and more drivers move to this new road. They will therefore find this road NOT TRAFFIC-FREE and some may move back to the original road.
In a word, these commuters will choose the less congested road if the traffic is NOT evenly distributed, so the traffic will be eventually evenly distributed. So I think C strengthen the argument. Welcome to discuss.

Hello expert,
this is what I think: As these commuters do not care pay the toll, there will be more and more commuters move to this new road. Then they will find the new road is NOT TRAFFIC-FREE again and some may move back to the original road.
In a word, these commuters will choose the less congested road as long as the traffic of the two road is NOT evenly distributed, so the traffic will be eventually evenly distributed. So I think C strengthen the argument.
And I wonder why E is wrong?
Since this question does not have OE, really need your opinion. Thanks in advance.

GMATNinja how does C weakens the argument ?
in worst case it strengthens by saying ppl dont mind paying extra toll so they are ready to move to new road and hence the traffic gets distributed.

please explain

D. The construction of the new road will not be completed for at least three years.
E. The north-south link road already has three parallel roads of 5 km each in different areas along its length.

Identifying the 'Conclusion' --> It is estimated that the traffic will be evenly distributed between the two roads only after a year, and so charging Rs 50 (possibly a hefty toll) is justified.

But, Option C mentions that the office going peope, primarily responsible for congestion, don't mind payimg up for a traffic-free ride. Consequently, these peope will prefer to travel by new road, and so traffic will get evenly distributed within a much shorter duration of time..THUS weakening the conclusion..

C) people will pick the newly build road and it will not make the distribution even- weakened.
