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.Adolescents playing video games has risk of developing carpal tunnel syndrome
( Adolescents who do not play video games
Now, a little bit of mathematics here ( Coz , I love it )
Red part is the determining factor here , if it is 0 then the Blue part will be zero ad that would mean - Adolescents playing video games has risk has the same risk as Adolescents who do not play video games.
So , there must be some +ve value for the red highlighted part ( Risk of carpal tunnel syndrome in Adolescents who do not play video games )We can safely conclude that carpal tunnel syndrome occurs in Adolescents who do not play video games but chances are less in comparison with those playing video games.
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.
Whats the use of Legislation/Bill - The problem exists and the doctor's assumption is not based on who votes for a Bill.
B. Not all adolescents who play video games on a regular basis suffer from carpal tunnel syndrome.
Not all - Some ( who play video games on a regular basis suffer from carpal tunnel syndrome ) definitely suffers , that's enough for us - We are not considering all adolescents playing video games will develop carpal tunnel syndrome.
C.Playing video games is the only way
an adolescent can develop carpal tunnel syndrome.
There might be some other ways as well ( Which we are unaware of , at least currently)
D.Most parents would refuse to purchase video games for their adolescent children.
Surely they will do so , who will like their children to suffer from carpal tunnel syndrome.
E. The regular playing of video games by adolescents does not produce such beneficial effects as better hand-eye coordination and improved reaction time.
This is leading to something else ( tried to board an aircraft instead boarded an airship )
Only (D) & (B) looks promising.
Consider something different , What might have forced the doctor to bring so much survey and evidence ? Why is this whole thing discussed ?
(B) - Is it because some adolescents playing video games on regular basis and yet not developing carpal tunnel syndrome.
(D) - Why most parents are refusing to purchase video games for their adolescent children ?
(D) looks best hence D seems the best answer...
