An avid television viewer is statistically more likely to take sleeping pills at bedtime than a person who enjoys listening to classical music but does not watch television as a habit. Clearly, listening to classical music just before bedtime contributes to a more restful night’s sleep, whereas watching television before bedtime has the opposite effect. Which of the following, if true, most seriously weakens the above argument?

A. People who enjoy classical music typically like to read just before bedtime.
B. Reading a book before bedtime contributes to restful sleep more than listening to music does.
C. Sleeplessness is more common among people who watch late-night television than among people who do not.
D. Engaging in a bedtime activity that is mentally stimulating often interferes with a person’s ability to fall asleep.
E. A silent environment is less conducive to restful sleep than an environment with calming ambient sounds.
