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.

Assumption : type Supporter
Test : Negation. (should weaken the conclusion)
POE : A,D prevail

D :Most parents would not refuse to purchase video games for their adolescent children.

Dosen't seem to affect the conclusion which states about legislators.
A: The majority of federal legislators would not vote for a bill that prohibits the sale of video games to minors.

Legislation won't pass.Hence weaken.
Clear choice A.
thank you

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?

Fedral registration prohibits sale of video games for minor only and If parents buy these game then whatever fedral legislation has thought will fall as parents are no minors so D is correct ans.

Why not C?

I would go with C.

If there is some alternate cause for carpal tunnel syndrome, the Federal legislation would NOT help curb this painful condition among adolescents.

So this option is defender.

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.

This one was not so difficult

Statement 1: playing video games, children may have disease
Statement 2: Federal regulation should act in order to lessen the probability to a child play this video game

To support statement 2, we need to know whether the federal regulation will be effective (so it has to say something about the kids, parents... etc.

A) As I said, out of scope
B) It would not support federal actions
C) Too narrow and would not help feds
D) Looks fine... what's next?
E) It neither strengthens nor weakens the argument

So, D

This is what we at Knewton call a "negate weakener" question (others, including those in this forum, use the word "defender," which is not as clear, IMO). The assumption on which the argument depends is in disguise; what it really does is present a weakener to the argument and then assure us that the weakener is not in fact true. To spot these, deny the assumptions to reveal the weakener.

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

Negate it:

-d) Most parents would NOT refuse to purchase video games for their adolescent children.

Well, if most parents would buy video games, then prohibiting adolescents from buying them themselves would not work. There would be an alternate strategy by which adolescents could acquire their games. Therefore, (-d) must be FALSE, and (d) must be TRUE.

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

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 answer is D for sure...

A: Goes to legislature otes which is none of concern for Doctor

B: Obviously out

C: He never believes it is the only reason...He believes it increases chances adn he wants to curb it

D: If you note SALE OF GAMES TO MINORS shud be banned. Which means he believes it would reach adolescents only if THEY THEMSELVES BUY IT...Which means parents will not buy it.

E : Is ridiculous

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

By POE,
C and D remain good contenders.

But, one thing that could eliminate C - Always choose options that uses more info given in the question.
C tries to be a little OOS, and speak about an assumption that is all beyond the legislation itself. Whereas, D speaks of the legislation(Legislation passed, Yet parents could buy), and thus is more relevant in GMAT.

Yes C is a little too extreme I think.

Answer has to be D for the conclusion to hold firm about sales.

My choice is D as well. The conclusion is stating that the legislation would help curb the wrist problem. The main issue here is that prohibiting the sale of it would reduce carpel tunnel. However if there is a way to go around this law then it would make defeat the purpose of creating this legislation.

To continue on that point... Sorry for not completing it.
That would make A out of scope and D would assume that parents are not bending the law.

+ 1 for D.In most cases it is the adults who buy video games for their children so banning the sail of video game would not curtail the problem, but making parents aware of carpel tunnel will definitely help.

I saw this in the GMAT review, the answer is D.

If legislature prohibits sale to minors, what's to stop parents from buying in for their kids?

In option choice "D"

applying negation technique:
Most parents would no refuse to purchase video games for their adolescent children.
hence they will refuse to purchase,but then children can get video games from other sources as well
such as video games parlor,friends,siblings,piracy etc.
how can we assume the above statement then?
