Winston: The Public Transportation Authority (PTA) cannot fulfill its mandate to operate without a budget deficit unless it eliminates service during late-night periods of low ridership. Since the fares collected during these periods are less than the cost of providing the service, these cuts would reduce the deficit and should be made. Transit law prohibits unauthorized fare increases, and fare-increase authorization would take two years.
Ping: Such service cuts might cost the PTA more in lost fares than they would save in costs, for the PTA would lose those riders who leave home during the day but must return late at night. Thus the PTA would lose two fares while realizing cost savings for only one leg of such trips.

Which one of the following, if true, most strongly supports Ping's conclusion?
(A) Over 23 percent of the round trips made by PTA riders are either initiated or else completed during late-night periods.
(B) Reliable survey results show that over 43 percent of the PTA's riders oppose any cut in PTA services.
(C) The last time the PTA petitioned for a 15 percent fare increase, the petition was denied.
(D) The PTA's budget deficit is 40 percent larger this year than it was last year.
(E) The PTA's bus drivers recently won a new contract that guarantees them a significant cash bonus each time they work the late-night shifts.

[spoiler]OA: A[/spoiler]. Why is B wrong

Remember Ping's conclusion was, "service cuts might cost the PTA more in lost fares than they would save in costs". B is wrong because its irrelevant whether the people support the plan or not. The passage does not give us any information how dissaproval of the policy would translate monetarily or how it would affect ridership. So we can't say what effect it would have on ridership or cash flow, so on its own right B doesn't strengthen Ping's point of view.

A correct.
B is not saying anything about late night services, so out of scope.

You probably chose B because of the higher percentage listed in the option. The emphasis here is not on how many people oppose the cut in services. This has nothing to do with the PTA costs.
On the other hand option A, which has a small percentage compared to B, hits the main point made by Ping about the effect of round trip reductions on the PTA costs.
