Difficulty:


A cost-effective solution to the problem of airport congestion is to provide high-speed ground transportation between major cities lying 200 to 500 miles apart. The successful implementation of this plan would cost far less than expanding existing airports and would also reduce the number of airplanes clogging both airports and airways.

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 high-speed ground-transportation system would require major repairs to many highways and mass-transit improvements.

(B) One-half of all departing flights in the nation’s busiest airport head for a destination in a major city 225 miles away.

(C) The majority of travelers departing from rural airports are flying to destinations in cities over 600 miles away.

(D) Many new airports are being built in areas that are presently served by high-speed ground-transportation systems.

(E) A large proportion of air travelers are vacationers who are taking long-distance flights.

B is the answer. It strengthens the argument by supporting the justification of high speed ground transportation.

The answer is in this case has to be B.

A. Provides a reason not to build the high speed ground transportation - weakens argument

B. Provides a good reason why this high speed ground transportation should be built (to reduce congestion in the airport) - strengthens argument

C. Since we are discussing travel between major cities, this is irrelevant. This answer all weakens the argument because it mentions that travelers would be going to destinations over 600 miles away.

D. Expanding airports is not what you want since high speed ground transportation is already present. - weakens argument

E. If a large proportion of travelers take long distance flights, implementing this plan would not be useful. - weakens argument

I agree with B as the best answer - but I don't think that it's a great answer either..

You have to make the assumption that the busiest airport is representative of other airports which could be a stretch?

Vote for B

Plan = provide high-speed ground transportation between major cities lying 200 to 500 miles apart is a cost-effective solution to airport congestion.
P1 : Plan will
- cost less than expanding existing airports
- reduce the number of airplanes clogging both airports and airways.
[So we have to consider that above information provided is true and we have to provide additional premise to support the plan]


(B) One-half of all departing flights in the nation’s busiest airport head for a destination in a major city 225 miles away.
=> This validates the soundness of the plan because the major destinations are 225 miles aways

(A) An effective high-speed ground-transportation system would require major repairs to many highways and mass-transit improvements.
--> this will weaken the solution

(C) The majority of travelers departing from rural airports are flying to destinations in cities over 600 miles away.
--> if they are flying 600 miles away then the plan will not work

(D) Many new airports are being built in areas that are presently served by high-speed ground-transportation systems.
--> this doesnot support the plan. if there is already a high-speed ground transport system, why do we need new airport? It will increase the cost.

(E) A large proportion of air travelers are vacationers who are taking long-distance flights.
-- Out of scope

Answers in B, since half of the departing flights are 225 miles away, providing a high speed ground transportation option between 200 to 500 miles will lessen the burden.

(E) A large proportion of air travelers are vacationers who are taking long-distance flights.


Conclusion : Cities that are closer should be road connected rather then by air planes.
Option B suggest that planes are going to a place that is 225 kms and can be connected through road.

A cost-effective solution to the problem of airport congestion is to provide high-speed ground transportation between major cities lying 200 to 500 miles apart. The successful implementation of this plan would cost far less than expanding existing airports and would also reduce the number of airplanes clogging both airports and airways.

Problem : Airport congestion due to clogging of airplanes
Plan/Cost-Effective Solution : To provide high-speed ground transportation between major cities lying 200 to 500 miles apart.

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 high-speed ground-transportation system would require major repairs to many highways and mass-transit improvements.
This is providing a drawback for the plan. It weakens. By emphasizing the likely costs of providing high-speed ground transportation is not by itself a solution to airport congestion. Therefore, incorrect.


(B) One-half of all departing flights in the nation’s busiest airport head for a destination in a major city 225 miles away.
It supports by providing the fact that one-half of all departing flights in the nation’s busiest airport head for a destination in a major city 225 miles away. Also, the plan is to provide high-speed ground transportation between major cities lying 200 to 500 miles apart. Thus, its the correct answer.
Option B indicates that between the cities to be served by the plan there is substantial air travel to which ground transportation would represent an alternative.


(C) The majority of travelers departing from rural airports are flying to destinations in cities over 600 miles away.
It weakens as flights are flying to destinations in cities over 600 miles away. The plan is for major cities lying 200 to 500 miles apart.

(D) Many new airports are being built in areas that are presently served by high-speed ground-transportation systems.
It suggests that already new airports are built so use them instead of providing the high-speed ground-transportation systems. It weakens.

(E) A large proportion of air travelers are vacationers who are taking long-distance flights.
Long distance flights, weakens the soundness of the above mentioned plan. Incorrect.

C and E say that there are many travelers for whom the proposed system would actually provide no alternative.
