There is only one major road, Freeway Z, that links County X and County Y. The border of the two counties is primarily defined by a mountain range, over which the construction of new roads is severely restricted by environmental laws. A cost-effective solution to the problem of traffic congestion on Freeway Z is to build a commuter train tunnel through the mountain range. The successful implementation of this plan would cost far less than expanding the existing freeway and would also reduce the number of cars clogging the roads in both counties.

Which of the following, if true, could proponents of the plan above most appropriately cite as a piece of evidence for the soundness of their plan?

A. An effective commuter train tunnel between the counties would require major investment in mass transit within both counties.
B. The majority of all vehicles on the nation’s freeways are traveling from one state to another.
C. 60% of the cars on Freeway Z are driven by people who live in County Y and work in County X.
D. Many new freeways are being built in areas that are presently served by commuter trains.
E. A large proportion of the vehicles on Freeway Z are commercial trucks carrying transcontinental shipments.

[Reveal] Spoiler:
This is 300-500 difficulty question as specified in Mgmat test. I got it wrong! Please, explain your logic.
I will post OA & OE later.
[Reveal] Spoiler: OA

We are looking for something that will support the plan to build a train track.

NOT RELEVANT A. An effective commuter train tunnel between the counties would require major investment in mass transit within both counties.
NOT RELEVANT B. The majority of all vehicles on the nation’s freeways are traveling from one state to another.
This shows that at least 60% of the commuters everyday are dailing commuters and there is a possibility that these people will ride the train. C. 60% of the cars on Freeway Z are driven by people who live in County Y and work in County X.
Again, not relevant D. Many new freeways are being built in areas that are presently served by commuter trains.
No connection to the question E. A large proportion of the vehicles on Freeway Z are commercial trucks carrying transcontinental shipments.

You're looking for an answer that could be used as further evidence for the soundness of the plan-- in other words, a new premise that will SUPPORT/STRENGTHEN the conclusion that successful implementation of the plan will (1) cost less than freeway expansion and (2) reduce congestion in both counties.


(A) We're looking for something to help prove that the tunnel would cost LESS than freeway expansion. We don't know anything about the cost of freeway expansion (although the expansion sounds difficult, and probably expensive), but this choice makes the tunnel sound really expensive! Eliminate.

(B) If most vehicles on the freeway are taking interstate trips, then the tunnel linking County X and County Y would probably not reduce congestion in these counties, since the majority of that congestion is coming from vehicles that would stay on the interstate freeway. Eliminate.

(D) That's nice, but does it affect our conclusion? Who cares about "many" freeways -- we only care about Freeway Z, and Counties X and Y.

(E) Transcontinental trucks probably wouldn't be hugely motivated (or even know about) a direct tunnel between counties X and Y. This choice is out for the same reason that choice B is out.

If 60% of the traffic on the freeway is from people commuting between X and Y, then a commuter train between these two cities might well be an appealing solution to their transportation needs, and motivate them to abandon driving on the congested highway. Does this choice prove the conclusion? Absolutely not. But it does provide additional support (and the other answer choices have concrete flaws that knock them out entirely).

Option C is the correct answer but I am really struggling to accept this. Option C says "60% of the Cars on the Freeway....." The freeway could have had cars, trucks, buses..etc. Out of which only 60% of the cars are mentioned in this choice. Also the total number of cars could be as low as 2 or 3 cars as opposed to 2000 or 3000 trucks and buses.
So shouldn't I eliminate C?

basically C states the proportion 60% on the road are most frequent travelers as they have their job in other state hence they will for sure commute the maximum and hence this lays stress on the conclusion that the number of cars clogging will be reduced.

hence C is the best choice over here.

C

This is a strengthen the conclusion question

He have to support the conclusion of proponents that "Build a Train commute is the best alternative"
Conclucion : The successful implementation of this plan would cost far less than expanding the existing freeway and would also reduce the number of cars clogging the roads in both counties

A. An effective commuter train tunnel between the counties would require major investment in mass transit within both counties.
--> This will Weaken the conclusion

B. The majority of all vehicles on the nation’s freeways are traveling from one state to another.
--> Not relevant - arugment doesnot talk about the travellers between States

C. 60% of the cars on Freeway Z are driven by people who live in County Y and work in County X.
--> Keep it (talks about the Freewaty Z and County X and Y and support the conclusion)

D. Many new freeways are being built in areas that are presently served by commuter trains.
--> Not relevant

E. A large proportion of the vehicles on Freeway Z are commercial trucks carrying transcontinental shipments.
--> Doesnot support the conclusion

Why not E because the load of the commercial trucks could be carried on the railway easily whereas the daily commuters might be particular about travelling through the road because there might be a connectivity issue or things like those from the railway stations to their work place or to wherever they commute daily. So, people might still have reasons like save their time because of the travel from the railway station to their work places whereas truck loads wouldn't have any such constraints. So, E sounded better in my mind than option C. Please help me understand the answer better. thank you very much.

This is a strengthen question, which means that the answer choices can include new information. C is the right answer as it clearly states that a high percentage of people travel between city X and Y. B is a trap answer as it just mentions cities.
A and D weaken the argument while E is irrelevant.

b is a trap answer, if they build the train, traffic won't necessarily be relieved. Commuters may use the train but the traffic might just be due to people passing through.

Hi Mun,

Here is my thinking as I went through this question... I hope it helps.

There is only one major road, Freeway Z, that links County X and County Y. The border of the two counties is primarily defined by a mountain range, over which the construction of new roads is severely restricted by environmental laws. A cost-effective solution to the problem of traffic congestion on Freeway Z is to build a commuter train tunnel through the mountain range. The successful implementation of this plan would cost far less than expanding the existing freeway and would also reduce the number of cars clogging the roads in both counties.

OK. So basic structure is that very expensive to build new roads between X & Y. So why not build a train instead, it's cheaper and would ease congestion.

Which of the following, if true, could proponents of the plan above most appropriately cite as a piece of evidence for the soundness of their plan?

So, this is a STRENGTHEN question. We're looking for something below that backs up the argument. So lets see what below suggests that trains would be better...

(A)An effective commuter train tunnel between the counties would require major investment in mass transit within both counties.

No. This is not correct. We're looking for things that make the train cheaper. This is providing extra costs for the train option. No good.

(B)The majority of all vehicles on the nation’s freeways are traveling from one state to another.

No. This is irrelevant. It talks about the nation, we're only interested in County X &Y.

(C)60% of the cars on Freeway Z are driven by people who live in County Y and work in County X.

Good. This looks good, the cars already on Z are used for commuting, so a train would serve them well. This suggests a train would be useful and successful

(D)Many new freeways are being built in areas that are presently served by commuter trains.

Irrelevant. This is not linked specifically to County X & Y.

(E)A large proportion of the vehicles on Freeway Z are commercial trucks carrying transcontinental shipments.
No. This weakens. If this were true, a train would have little or no effect, as the transcontinental shipments would not be able to se it

Hope that helps. As others have said B is the tricky one, but key always to ensure the evidence provided is directly relevant to the situation described. In B this time that is not the case, as the answer choice talks about 'nation' whilst we're worried about County X & County Y

I think this is where the problem lies. In some CR questions you really have to twist your mind out of the way to come up with an answer. In this case, although a lot of you say E is "irrelevant", I don't think it is irrelevant. It might not be a strong contender. I don't know if many of you are aware of the concept of Goods Trains. If a large proportion of the vehicles on the highway are trucks trucks carrying those shipments then it would definitely benefit to take those trucks off the roads and put the shipments they carry on the trains thereby getting rid of the large proportion of traffic. If C wasn't mentioned E would have been the answer.
