D is best. To get around the law, children will simply ask their parents (adults) to buy the games.

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.
Spoiler: :: OA
D

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.

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!

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

Clearly 4. The argument assumes that if the law prohibits minors from buying the video game then their parents won't buy it for them. If the parents start buying then the whole argument falls apart.

I originally thought (C), but it looks like I fell for a typical pitfall and the answer should be (D). It's a bit tricky.

Once you see the word "assumptions" in the question, you should look back at the paragraph to see what claim is being made.

Here's the claim:
"Stopping sales of video games --> less carpel tunnel syndrome"

Well, wait a minute. Look at the long chain of reasoning here:

There are 3 components:
1) Sales of video games -> 2) playing video games -> 3) carpel tunnel syndrome

More detailed, it looks like this:
1) Legislation that stops sales of video games --(causes)--> 2) playing video games --(causes)--> 3) carpel tunnel syndrome

Here's the doctor's claim: "Federal legislation that prohibits the sale of video games to minors would help curb this painful wrist condition among adolescents. "

According to the reasoning chain above, getting rid of item #1: "sales of video games" through legislation will mean #2 and #3 will not exist.

Well, that assumes that #1: "sales of video games" will lead to #2: "playing video games"
How do we know that blocking sales of video games will necessarily lead to less playing of video games?

Well, the doctor assumes that by making it illegal for minors to purchase to purchase the games, the minors would have no other way to play the games. Well, common sense tells you that the minors can always get their parents/guardians to get the games for them. So the author assumes that this is not possible since they assume "most parents would refuse to purchase the games for their kids."

With answer choice (D), that's what you get:

"Most parents would refuse to purchase video games for their adolescent children."

I still think answer (C) is an assumption in the 3 part assumption chain I mentioned above although it's not an assumption of the doctor's claim---small subtlety.

Here's why:

In the 3 part reasoning chain:
1) Sales of video games -> 2) playing video games -> 3) carpel tunnel syndrome

the doctor's claim is that getting rid of #1, you will no longer have #3.
Answer (D) describes the assumption between #1 and #2.
Answer (C) describes the assumption between #2 and #3.

Since the doctor's claim begins further to the left on the reasoning chain (#1), the assumption must include #1. Although (C) seems like a legitimate assumption to me, it is an assumption related to a different part of the reasoning chain (#2 and #3).

So it appears because of where we are on this reasoning chain, the answer is not (C) but rather (D).

Open to your thoughts.

The OA is .

OE

In order for the doctor's recommended legislation to reduce the incidence of carpal tunnel syndrome among adolescents, the prohibition from the purchase of video games must result in the actual possession of fewer video games. Thus, it must be assumed that parents will not simply purchase video games for their children.

This is actually an excellent GMAT trap question. The question is to identify the assumption, not to see if the conclusion can fall apart or not. Classic difference between strengthening the stimulus and understanding the core logic in the stimulus to drive to the conclusion.

The techniques that honeyrai and gmatpill both used are applicable for strengthening the conclusion. Playing more video games causes carpal tunnel syndrome - a regular cause and effect scenario. Negating the cause, or breaking the relationship, or showing that no alternatives exist between the cause and effect are all techniques applicable for either strengthening or weakening questions.

Assumption on the other hand tries to justify the conclusion. A premise is presented that teenagers run a greater risk when they play more video games. The conclusion drawn is that prohibiting sales of video games should fix the problem. What could possibly justify the conclusion? Cigarette smoking is always advertised as injurious to health, yet, some states literally survive on taxes that come from the sales!!!! In similar lines, even if sales of video games are prohibited, rather restricted, it is up to the parents to make sure they don't buy neither do they allow their teenagers to buy those games anymore. Until that is assumed, the conclusion cannot stand on it's own!!!!

True, the answer must be D.

Nice explanation Barney.

However, wouldn't the legislation prevent parents from making purchases anyways, thus making option 4 slightly out of scope?
(I think the example of cigarette is not completely analogous to this one.)
I find option 4 definitely close but still like 3, however 4's the OA and we have to live with it!

Yes, good points there. Btw, I also agree (C) is a legitimate assumption (I originally chose C) but I believe there's a small subtlety in the 3 part reasoning chain that explains why (D) turns out to be the answer instead of (C). See if it makes any sense.

I edited my above response above to include this explanation.

Excerpt:
Quote:

I think that if C had stated something like "sales to minors will completely curb the syndrome" then it would have been a strong candidate. But here C only says that the legislation will help curb the problem. It doesn't say that it'll eradicate the problem. Curbing a problem signifies reducing the problem. Therefore, the doc certainly accepts the fact that there are other ways in which this syndrome can be developed. Hence C isn't an assumption.

(A) The majority of federal legislators would vote for a bill that prohibits the sale of video games to minors.
-->Though this is possible the conclusion is stating what WOULD happen if sales to minors were prohibited. We don't need to know whether or not the bill passes.
(B) Not all adolescents who play video games on a regular basis suffer from carpal tunnel syndrome.
-->The conclusion does not depend on this statement. If not all adolescents who play videos on a regular basis don't get CTS then the legislation that prohibits the sale of video games doesn't matter.
(C) Playing video games is the only way an adolescent can develop carpal tunnel syndrome.
-->If playing video games is the ONLY way an adolescent can develop CTS then the law would not just "help curb" but would ELMINATE CTS for good.
(D) Most parents would refuse to purchase video games for their adolescent children.
-->If minors can't buy games they will rely on non-minors to purchase it for them. If most parents refuse to purchase video games then CTS will be curbed among adolescents. CORRECT
(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 statement has nothing to do with our conclusion.


Conclusion: Federal legislation that prohibits the sale of video games to minors would help curb this painful wrist condition among adolescents.
Assumption: No one else buys the game for the minors
