直接上题 Doctor: Research shows that adolescents who play video games on a regular basis are three times as likely to develop carpal tunnel syndrome as are adolescents who do not play video games. Federal legislation that prohibits the sale of video games to minors would help curb this painful wrist condition among adolescents. The doctor’s conclusion depends on which of the following assumptions?
A The majority of federal legislators would vote for a bill that prohibits the sale of video games to minors. B Not all adolescents who play video games on a regular basis suffer from carpal tunnel syndrome. C Playing video games is the only way an adolescent can develop carpal tunnel syndrome. D Most parents would refuse to purchase video games for their adolescent children E The regular playing of video games by adolescents does not produce such beneficial effects as better hand-eye coordination and improved reaction time.
one of th ebest ways to solve "assumption" problem is to negate the assumption and the conclusion should fall apart..
if we negate C, what do we have
Playing video games is NOT the only way an adolescent can develop carpal tunnel syndrome.
now it tells us that there could be other factors for CTS (carpal tunnel syndrome) ... OK fine but it doesnt rule out the possibility that playing video games is also one of the factors ... So a ban will help curm the CTS ... argument doesnt fall apart.... so C is not the answer 参见http://gmatclub.com/forum/doctor-research-shows-that-adolescents-who-play-video-games-68433.html
