LR question~~
« on: September 24, 2007, 09:37:44 PM »
 A 1991 calculation was made to determine what, if any, additional health-care costs beyond the ordinary are borne by society at large for people who live a sedentary life. The figure reached was a lifetime average of $1,650. Thus people's voluntary choice not to exercise places a significant burden on society.

Which one of following, if true and not taken into account by calculation, most seriously weakens the arguemnt?

A) Many people whose employment requires physical exertion do not choose to engage in regular physical exercise when they are not at work.

C) Physical conditions that eventually require medical or nursing-home care often first predispose a person to adopt a sedentary lifestyle.

Can anyone explain this problem? I don't understand why the correct answer is correct and why the wrong ones are wrong.  :(

Is the answer A? If your job requires physical exertion, that means you're not sedentary.  Therefore, if you chose not to exercise, you wouldn't be placing burden on society. 

C doesn't attack the conclusion that sedentary lifestyles place a significant burden on society.  It just explains why people are sedentary.

I could be wrong...

I think (c) would be correct if the conclusion were reversed where the burden on society is only from voluntary choices.  (c) says that I'm sedentary because I'm physically impaired, not because I chose to be this way.

I still think it's (a). Anyone else?

I don't think answer choice C is saying that their sedentary lives are involuntary.  It's going to a correlation/causation argument instead.  C indicates that those who are already likely to require more health care over their lives often voluntarily choose to live a sedentary lifestyle (note the word choice of "adopt").  Thus there's more support for the conclusion that those who have high health care expenses have sedentary lifestyles because of an underlying cause which is also the cause of their increased health care expenses, not that the choice of a sedentary lifestyle itself causes the increased costs.

Hmm, I see your point. So it is C and E reversed right? I guess that makes it even more clear now.
