traffic congestion

[thephoenix]

Eva: A "smart highway" system should be installed, one that would monitor areawide traffic patterns and communicate with computers in vehicles or with programmable highway signs to give drivers information about traffic congestion and alternate routes. Such a system, we can infer, would result in improved traffic flow in and around cities that would do more than improve drivers' tempers; it would decrease the considerable loss of money and productivity that now results from traffic congestion.
Luis: There are already traffic reports on the radio. Why would a "smart highway" system be any better?

Eva's argument depends on the assumption that

(A) on "smart highways" there would not be the breakdowns of vehicles that currently cause traffic congestion
(B) traffic lights, if coordinated by the system, would assure a free flow of traffic
(C) traffic flow in and around cities is not now so congested that significant improvement is impossible
(D) the type of equipment used in "smart highway" systems would vary from one city to another
(E) older vehicles could not be fitted with equipment to receive signals sent by a "smart highway" system
OA to follow soon

IMO: C
Conclusion: Improved traffic flow is possible if "smarty highway" system is installed
Assumption: Depends only on Eva's argument. So Eva is assuming that improvements in traffic flow is feasible.

IMO ans is B

Luis is arguing for radio system where as Eva is arguing for smart system.
Eva argument is better than Luis only if smart system is doing something which is better than radio system.

And I think B indicates clear cut advantage of smart system

[gsinghal]

IMO C. It states that there is still a possibility of improvement and that is what the option C is referring to. Look at the Luis's point : Why would a “smart highway� system be any better.

Wats tha OA?

[thephoenix]

OA is C
thanks to all for the help , but i was looking for y B is incorrect

[paddle_sweep]

'C' seems to have another assumption that even if the improvement is not significant, considerable loss of money could be avoided. Could somebody throw more light on this?

[ThiMBA]

I ruled out B because it made reference to traffic lights and at no point during Eva's argument did she make specific mention of traffic lights (only computers and programmable highway signs)

hope this helps

[jeffedwards]

The phoenix -

The same as ThiMBA - I ruled out B, because it was too specific. The assumption does not depend on this. There could be an alternate system to improve the situation such as something that could "communicate with computers in vehicles" and so on...

The argument is that people could be rerouted. C is saying that the other streets are not overly congested...so rerouting would work. If the alternate routes were also congested then traffic wouldn't see a significant improvement by rerouting. Does that make sense?
