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:
The argument has two major points:
1. The plan costs far less than building highways
2. The plan could reduce the number of cars clogging roads
A. Large portion of people on the road are people traveling out of town for vacation.
Correct. This choice strengthens the argument (point 2). Many people travel out of town (for whatever reason) so they could take the mass transit. Hence, the traffic congestion problem could be solved effectively. 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.
This choice weakens the argument (point 2). If most people still has to drive, they are unlikely to take the transit.C. Many new highways are being built in areas where a mass transit sub-structure already exists.
This choice weakens the argument (point 2). There are many new highways that are being built in areas where a mass transit sub-structure already exists indicates that the plan to build flexible mass transit could be ineffective and implementing both 2 plans could cost much unnecessarily.D. An effective mass transit system would require major repairs to many highways and the current intra-city mass transit system.
This choice weakens the argument (point 1). This plan would require additional cost so it could cost far more than building new highways.E. Less than 20% of all cars on the road in urban environments are headed to or from the suburbs.
This choice weakens the argument (point 2). If this plan is implemented, the traffic congestion is still a main problem since the plan could reduce less than 20% of all cars on the road.
