A cost-effective solution to the problem of urban-suburban traffic congestion is to provide timely flexible mass transit options between the suburbs and the city. The successful implementation of this plan would cost far less than building more highways and would also reduce the number of cars clogging roads in both urban and suburban environments.
Each of the following, if true, would provide opponents of the plan outlined above with a means of weakening the argument EXCEPT:
A. Large portion of people on the road are people traveling out of town for vacation.
B. Because the suburbs are spread over a large area most residence would have to drive several miles on a highway to reach a transit station.
C. Many new highways are being built in areas where a mass transit sub-structure already exists.
D. An effective mass transit system would require major repairs to many highways and the current intra-city mass transit system.
E. Less than 20% of all cars on the road in urban environments are headed to or from the suburbs.

All the options except A weakens the argument....
Large portion of people on the road are people traveling out of town for vacation---this doesnot weaken the argument in any way...
Because the suburbs are spread over a large area most residence would have to drive several miles on a highway to reach a transit station-----clearly weakens...highway is required
Many new highways are being built in areas where a mass transit sub-structure already exists---If new highways are built where transit is already there then transit may not be effective in these areas....
An effective mass transit system would require major repairs to many highways and the current intra-city mass transit system---weakens cost issue
Less than 20% of all cars on the road in urban environments are headed to or from the suburbs---weakens as it wont be economical

What is the source of this Question please? The answer choices look too vague. Option A is quite open ended when we say that most people are traveling out of town for vacation. We cannot be sure if these people need to travel via suburbs to urban areas in order to reach their end destination out of town. If yes, then it is the correct option since it doesnt weaken the conclusion. But if these people do not necessarily have to travel via urban-suburban traffic and there is a different route for people who are travelling out of town then it is weakening the conclusion.
On the other hand, Option C also can be interpreted in 2 ways. New highways being built in an area where mass transit system already exists can be totally unrelated to the conclusion. If it is something that was started in the past and the action is continuing even today (constructing the highway) then how can we conclude that it weakens the conclusion?
