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.

The question of parents following legistation does not arise a legislation should be followed
I think we need more discussion on this one

C is irrelevant because the conclusion is focussed on how the legislation can curb the condition

COnsider this :
What is the Conclusion of the argument?

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

What is the evidence provided?
Research shows that adolescents who play video games on a regular basis are three times as likely to develop carpal tunnel syndrome

Paraphrase: Doctors know video games are the reason for Carpal tunnel syndrome in adolescents .If legistation is passed such that videos cannot be sold to minors the painful wrist condition can be curbed.

What is the gap between the conclusion and evidence?

Hope this helps.

The doctor’s conclusion depends on which of the following assumptions?

1]The majority of federal legislators would vote for a bill that prohibits the sale of video games to minors.
2]Not all adolescents who play video games on a regular basis suffer from carpal tunnel syndrome.
3]Playing video games is the only way an adolescent can develop carpal tunnel syndrome.
4]Most parents would refuse to purchase video games for their adolescent children.
5]The regular playing of video games by adolescents does not produce such beneficial effects as better hand-eye coordination and improved reaction time.

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).

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.
-->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

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!

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.

one of th ebest ways to solve "assumption" problem is to negate the assumption and the conclusion should fall apart..

if we negate C, what do we have

Playing video games is NOT the only way an adolescent can develop carpal tunnel syndrome.

now it tells us that there could be other factors for CTS (carpal tunnel syndrome) ... OK fine but it doesnt rule out the possibility that playing video games is also one of the factors ... So a ban will help curm the CTS ... argument doesnt fall apart.... so C is not the answer

fair bet, but if you look at the conclusion its " Federal legislation that prohibits the sale of video games to minors would help curb this painful wrist condition among adolescents."

the author is not concerned about whether the law will be passed, but will the law once passed help the reduction of the crap that ALL IT GUYS ARE PRONE TO......

So now if the parents or somebody help the guys to get games, there is no point in law, so he safely assumes that noone help the game freaks

hi guys had a doubt in this question
the author says that federal legislation would be helpful in curbing the problem,so one of his assumptions is that the legislation might be passed,thatis even the federal legislators would agree with his opinion on video games,so why cant (A) be a plausible option

Further to mailnavin1's point, an assumption supports the conclusion.
The conclusion here is "A law that prohibits sale of video games to minors would help curb this condition" i.e. a law would help.

If you want to negate this conclusion, you will say, "a law will not help." You will not say, "Such a law cannot be passed."

So this conclusion does not depend on whether the law will be passed. The author just says that if the law is passed, it will help. He assumes that a law will work because adults will not buy the games for minors.

IMO D.
The doctor's conclusion is ..Federal legislation that prohibits the sale of video games to minors would help curb this painful wrist condition among adolescents. In other words, the conclusion says "if such a law is passed, it will help"
Doctor does not conclude that this law will be passed... so B should not be the assumption.
However, the doctor's conclusion to be valid , the desired effect of the law should be achieved . For that D should be true ( assumption ).

I dont understand why D is the answer.
If most parents refuse to buy video game, what is the need for a law prohibiting its sale?

This is out of scope.

b) Not all adolescents who play video games on a regular basis suffer from carpal tunnel syndrome.
This is already stated by the doctor by "three times as likely to develop" so it does not add any additional information.

c) Playing video games is the only way an adolescent can develop carpal tunnel syndrome.
The conclusion does not rely on eliminating the syndrome, it only seeks to "help curb". So this is not a necessary assumption.

d) Most parents would refuse to purchase video games for their adolescent children.
This is necessary for the conclusion. The conclusion is if minors cannot purchase the game, this solves the issue. If there was another way for them to obtain the game the argument is significantly weaker. An example of this is parents buying the game for minors. This is the CORRECT answer.

e) The regular playing of video games by adolescents does not produce such beneficial effects as better hand-eye coordination and improved reaction time.
Other benefits of games are not in scope.

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.

Even though the prohibition is on force ,it will not have any effect if parents buy the game and give it to their children.Because the prohibition is only for minors.Hence D is the assumption,which has been taken by the doctor.

Explanation for this has been provided in MGMAT forum. However I am not very convinced with the arguments given there regarding D being the preferable choice over C. I think this question definitely needs editing. Choice D should be reworded something on the lines :

The law will prevent most parents from buying video games for their adolescent children.

Even though the current choice actually means the same, explicitly mentioning the relation between the law and sale of video games will make the choice clearer.

Why not C? Here the author says "prohibits the sale of video games to minors would help curb this painful wrist condition among adolescents. " Doesnt he assume here that the only cause for wrist condition is playing video games. If that is not the only cause, then this legislation will not have its intended effect.

As my mac dictionary says, 'curb' means 'keep in check'. It does not mean 'eliminate completely'. So as long as the legislation helps to reduce the incidence of carpal tunnel, it is having its intended effect. It doesn't make any difference if there are other causes. Taking a similar example, if I say that emissions controls on automobile exhaust will help reduce air pollution levels, I'm not assuming that automobiles are the *only* cause of air pollution; I'm only assuming that they are one cause.

I did not even read the option D completely....made it out of scope since Parents are coming into the discussion. Chose option C. On a second look, i realized that D is correct.

Lesson learnt : Read all options carefully. When you hit an interesting contender early on, you will start ignoring other options, coz of your bias towards an option and your brain asking you to rush to beat the time. Never ignore any option without completely reading it. I tell this to myself everytime, but somehow fall into the same trap again and again.
