Doctor: Research shows that adolescents who listen to music on headphones on a regular basis are three times as likely to develop serious hearing loss as are adolescents who do not use headphones. Federal legislation that prohibits the sale of headphones to minors would help to reduce the prevalence of hearing loss among adolescents.
In assessing the doctor’s assertion, it would be most useful to know which of the following?
a. percentage of federal legislators who would vote for a bill that prohibits the sale of headphones to minors.
b. The number of adolescents who use headphones on a regular basis but do not suffer from hearing loss.
c. The extent to which other common adolescent behaviors contribute to hearing loss.
d. The percentage of parents who would refuse to purchase headphones for their adolescent children.
e. The difference in level of hearing loss between adults who have used headphones since adolescence and those who began using headphones asadults.
