### HideShow timer Statistics

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 the following, if true and not taken into account by the calculation, most seriously weakens the argument?
(A) Many people whose employment requires physical exertion do not choose to engage in regular physical exercise when they are not at work.
(B) Exercise is a topic that is often omitted from discussion between doctor and patient during a patient's visit.
(C) Physical conditions that eventually require medical or nursing-home care often first predispose a person to adopt a sedentary lifestyle.
(D) Individuals vary widely in the amount and kind of exercise they choose, when they do exercise regularly.
(E) A regular program of moderate exercise tends to increase circulation, induce a feeling of well-being and energy, and decrease excess weight.

Please come with explanations. OA later.
[Reveal] Spoiler: OA

It's C; it's just a reversal of cause and effect. The argument says "people who choose not to exercise develop medical problems which cost society money." C says that the medical problems might instead cause people not to exercise. Those medical problems are then the source of the expense to society, and not people's unwillingness to exercise, as the argument claims.

None of the other answers even seem particularly relevant, so I think you could also arrive at the answer here by elimination.

whats wrong with a
i thought option a can impose a statistical error as the people who have lot of physical activity are more prone to hospitalization
but they are excluded from the people whoare involved in the physical exercise

looks like i have made lot of assumptions so i missed that one
but i think weakening question can bring new information into the argument

can i bring my assumptions along with information or they should be defined in the argument

You can bring in a new info in a weaken question for sure.

As far as "why A is wrong?" is concerned, The argument is targeting the people "WHO live a sedentary life" in the first line of the argument. This makes "people living actively at work" as in A to fall out of the set of people argument is referring to.

Also, the question stem refers unusually to "not taken into account by calculation" to raise the bells for making A out of league of probable answers.

Step 1:
Narrowed it down to A and C because of the following:
B: Doctors talks is not going to impact the calculation.
D: The "amount and kind of exercise" dont impact the calculation.
E: The characteristics about circulation and benefits dont impact the calculation.

Step 2:
A: A doesn't actually talk about people in Sedentary life. There is a difference. NOT EXCERSICING DOES NOT EQUAL SEDANTARY. Secondly, what if the many people we are talking about is only a say for e.g. ~1% of the entire population. Then this argument is invalid.
C: If he is forced to lead a sedantary life the calculation is ALL wrong in the first place.

Paraphrase the Q: Voluntary choice not to exercise.

A, B, D & E don't weaken the argument

Therefore C is the answer.

What is the OA?

C makes sense.
B, D and E can be ignored right away.
A and C made go back to passage again.
