Stimulus

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 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 savings for only one leg of such trips.

Which one of the following, if true, most strongly supports

Answer choices

  1. Correct88% picked this

    Over 23 percent of the round trips made by PTA riders are either initiated or else

    Why this is right

    This answer directly supports Ping's argument by providing a quantifiable measure of the number of riders affected by late-night service cuts. If over 23 percent of round trips involve late-night periods, this indicates a significant proportion of riders could potentially stop using the service due to the cuts, resulting in a substantial loss in fares.

    Skill tested: Strengthen · how this choice captures the argument's function is the move to repeat next time.

  2. No Impact6% picked this

    Reliable survey results show that over 43 percent of the PTA ’s riders oppose any

    While it provides information about public opinion regarding service cuts, this does not directly impact the analysis of fare loss vs cost savings. Whether riders oppose the cuts doesn't change the financial dynamics Ping is addressing.

  3. No Impact0% picked this

    The last time the PTA petitioned for a 15 percent fare increase, the

    The outcome of a past fare increase petition does not help us analyze the specific impact of cutting late-night services on the PTA's budget deficit.

  4. No Impact2% picked this

    The PTA ’s budget deficit is 40 percent larger this year than it

    Although this speaks to the general financial situation of the PTA, it doesn't specifically address whether late-night service cuts would be a net gain/loss in revenue compared to cost savings.

  5. Opposite (if anything)4% picked this

    The PTA ’s bus drivers recently won a new contract that guarantees them a significant cash bonus each time

    The fact that drivers make a lot more during the late hours means that the city would save a lot of money by eliminating those hours. That goes against Ping's conclusion. He thinks loss in revenue will outweigh cost savings, but this answer makes cost savings sound big.
