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!
