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.

In my opinion:
A - "majority"
B - opposite direction
C - Not mentioned as the only way
D - "Most"
(TRUE) E - Based on this assumption the doctor's conclusion is meaningful.

A. The majority of federal legislators would vote for a bill that prohibits the sale of video games to minors. ---> out of scope
B. Not all adolescents who play video games on a regular basis suffer from carpal tunnel syndrome. ---> opposite of the conclusion
C.Playing video games is the only way an adolescent can develop carpal tunnel syndrome. ---> never said that
D.Most parents would refuse to purchase video games for their adolescent children. ---> if they do then then there is no need to have legislation
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 one is left
So answer is E

Answer is C.

Because in the last line it says if the federal legislation prohibits the sale of game to adolescent, it can curb this painful wrist condition. Thus the author assumes there is no other thing than video games that causes this syndrome.

I don't understand why the OA is D. Can someone please explain it to me. Thanks.

Hey All,

I'm happy to help out on one of our questions!

The important thing with this question, as with the majority of CR questions, is to focus on the EXACT wording of the conclusion. In this case, we can paraphrase to say "Federal legislation that you can't sell games to minors will HELP PREVENT kids from getting carpal tunnel."

Now, let's go through the ACs.

A. The majority of federal legislators would vote for a bill that prohibits the sale of video games to minors.
-- The question isn't whether or not the legislation will pass, but what would happen if it did.

B. Not all adolescents who play video games on a regular basis suffer from carpal tunnel syndrome.
--This isn't the point either. We want to totally keep kids from getting carpal tunnel, so that only applies to the ones that do get it.

C.Playing video games is the only way an adolescent can develop carpal tunnel syndrome.
--This isn't the issue either. We never said we would stop all cases of carpal tunnel, but only that we would "curb" it.

D.Most parents would refuse to purchase video games for their adolescent children.
--Aha. Now we have a problem. If parents just go out and buy the games for their kids (because only minors were prevented from purchasing it in the legislation), then nothing is going to change.

E. The regular playing of video games by adolescents does not produce such beneficial effects as better hand-eye coordination and improved reaction time.
--The question isn't about whether video games are bad or good. The question is whether or not we can keep them from causing carpal tunnel.


The correct answer here is D.

Hope that helps!

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.

PR: 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.

CN: Federal legislation that prohibits the sale of video games to minors would help curb this painful wrist condition among adolescents.

Missing PR/Assumption: The legislation will actually be effective

So we need to find a AC which is serving the purpose.

Thanks tommy

D is defender assumption.
negation of assumption is an weakener which attack the link between evidence and conclusion.
if negation of an answer choice weaken ONLY CONCLUSION,or in other words, attack conclusion outside context of evidence, this answer choice is wrong and tricky. . I call this tricky answer affecting conclusion outside of evidence context. Defender assumption is usually mistaken for this tricky answer.

for many S, W, A, the wrong choice or negation of wrong choice support/weaken conclusion outside context of evidence . This is tricky. following is my example of this tricky. D is attacking conclusion outside context, very attractive but wrong.

Having an efficient, attractive subway system makes good economic sense. So, the city needs to purchase new subway cars, since the city should always do what makes good economic sense.
The conclusion drawn above follows logically if which one of the following is assumed?
(D) New subway cars are financially affordable.
(E) New subway cars are required in order for the city to have a subway system that is efficient and attractive

ok, understand ATTACKING CONCLUSION OUTSIDE CONTEXT OF EVIDENCE. also, understand DEFENDER ASSUMPTION which is explain in Critical Reasoning Bile.
