In an effort to increase the number of taxicabs available during the hours from 8:00PM to 6:00AM, the Taxi Commission, which sets fares, has proposed a $1 per-ride surcharge during those hours. This is unlikely to have any effect on the availability of taxis. The fleet owners who lease cabs to drivers on a shift basis will simply raise the per-shift charge for those hours, thus eliminating any incentive for the individual driver to work the nighttime hours.

Which of the following weakens the argument above?
A) Fleet owners usually have unleased cars during the nighttime hours covered by the Commission's proposal
B) Most people who need a taxi during the nighttime hours would not mind paying the $1 surcharge
C) The majority of licensed cabs are owned by individual drivers who do not lease them from fleet owners
D) The previous year the Commission approved a 10-percent increase in taxi fares
E) Passengers would not treat the surcharge as part of the driver's tip
