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.
Note that the conclusion says "Federal legislation that prohibits the sale of video games to minors would help curb this painful wrist condition among adolescents"
The conclusion says that it will help control the occurrence of carpal tunnel. It doesn't say that it will eradicate the condition. If a problem can happen in 3 ways and if you take care of one, you can certainly HELP CURB the problem. It may not eradicate the problem completely but it can definitely help reduce the occurence.
So we don't need to assume that carpal tunnel doesn't happen any other way to make our conclusion true. Therefore, C is not correct.
Take another example:
Me: I get frequent heartburns.
You: Avoid cooking fried foods at home. That would help control the problem.
Your opinion is that if fried food are not cooked at home, the heartburn problem will be controlled. What are you assuming? That I will not go outside/order in fried foods on a regular basis. You are not assuming that there is no other way in which I could get heartburn. Smoking, eating large meals etc can also cause heartburn. But you are addressing one cause, perhaps the main one - we don't know - and you are saying that taking care of this cause will help control the problem. That is perfectly valid, isn't it? You don't need to assume that other causes are not there.
