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.

[Reveal] Spoiler: OA
D


The guy who posted thisw question on the forum said the OA is D.
I agree on D but I feel C serves equally well.
If the carpal syndrome can be caused by things other than video games.then why will be the syndrome be curbed.
Curbed means stopped.
To undermine D , what if the adolscents are able to borrow the games from some of the older persons.
[Reveal] Spoiler: OA

I am agree with you mundasingh123 , the answer should be "C" instead of "D''
First of all, it is asked to find the supposition between evidence and conclusion and if D were the supposition then why would the legislature ban the video games. Parents themselves be able to reduce the carpel tunnel syndrome.

Secondly, since it used in the stimulus "video games to minors would help curb this painful..." in the last line of the stimulus, we can take it as legislation can completely tackle this problem with taking such step. Therefore i believe that the given evidence completely supports the supposition given in option "C", which leads to the given conclusion.

Hence, My answer is "C"

Great question - thanks for posting this one (and for the invitation to chime in!).

This is a terrific example of two crucial strategies for Assumption questions:

1) You have to identify the exact conclusion of any CR strengthen/weaken/assumption question

2) The assumption is something that is necessary to the argument; not merely something that would strengthen it


Here, the conclusion is that "prohibiting the sale of video games to minors would help curb carpal tunnel syndrome among adolescents. That's entirely different than something that would eliminate it.

The problem with choice C as it pertains to this conclusion is that the conclusion doesn't require video games to be the only or even a primary reason that kids develop this problem. Even if only 5% of carpal tunnel cases were related to video games, eliminating video games would still "help curb" the problem, however slightly. We don't need for video games to be the only reason that kids get this problem...we just need it to be one reason.


Now, with D, we need that to be the case - prohibiting "the sale of games to minors" doesn't necessarily mean that minors won't still play the games. In order to curb the problem we need to stop kids from playing the games, not simply from buying the games. If D were untrue - if it were the opposite - then we could say that parents will just buy these games for their kids anyway, so the kids won't stop playing the games. Therefore, we need D to be true - it's required by the argument otherwise the conclusion (that this law will help reduce the problem) isn't supported at all.
