Ten-year-old Timmy's new favorite show, "Gargantron," is a robot-cartoon. On Friday nights, after Timmy watches the show, he usually has trouble sleeping. Timmy's parents have decided that his sleep will improve if they prohibit him from watching "Gargantron," because the cartoon has some parts that could be considered scary for children under 12 years of age.
Which of the following casts the most doubt on Timmy's parent's plan?
A. Timmy's 11-year-old friend Alex watches Gargantron regularly and has no difficulty sleeping after the show.
B. The producers of "Gargantron" have stated that the cartoon is suitable for viewers 10 years of age and older.
C. Many current TV shows have content that could disrupt the sleep patterns of younger viewers.
D. "Gargantron" has been tested with viewer focus-groups including children approximately Timmy's age.
E. On Friday nights Timmy's parents allow him to watch their favorite show, "Cop World," a crime drama intended for adults.
