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.

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.
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.

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 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.

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.

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!

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.

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

A --> Conclusion does not focuses on Federal legislation
B --> Alreay stated in the argument (three times as likely to develop)
C --> Not stated in the argument
D --> Work as the missing link ( This is correct)
E. --> Out of scope

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).

OE

[Reveal] Spoiler:
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.
