The more viewers a television show attracts, the greater the advertising revenue the show generates. The television network Vidnet's most popular show, Starlight, currently earns the network's highest profits, but next year, because of unavoidable increases in production costs, its profits are projected to fall to below the average for Vidnet shows. Therefore, Vidnet would earn greater profits overall if it replaced Starlight with a show of average popularity and production costs.
Which of the following, if true, most seriously weakens the argument?
(A) The average profits of Vidnet shows have increased in each of the last three years.
(B) Shows that occupy time slots immediately before and after very popular shows tend to have far more viewers that they otherwise would.
(C) Starlight currently has the highest production costs of all Vidnet shows.
(D) Last year Vidnet lost money on a weekly show that was substantially similar to Starlight and was broadcast on a different day from Starlight.
(E) Even if, as a result of increased production costs, Starlight becomes less profitable than the average for Vidnet shows, it will still be more profitable than the average for television shows of all networks combined.
