(N/A)

Question Stats:

73% (02:18) correct 27% (01:26) wrong based on 4 sessions
A long-term health study that followed a group of people who were age 35 in 1950 found that those whose weight increased by approximately half a kilogram or one pound per year after the age of 35 tended, on the whole, to live longer than those who maintained the weight they had at age 35. This finding seems at variance with other studies that have associated weight gain with a host of health problems that tend to lower life expectancy.
Which one of the following, if true, most helps to resolve the apparently conflicting findings?
(A) As people age, muscle and bone tissue tends to make up a smaller and smaller proportion of total body weight.
(B) Individuals who reduce their cholesterol levels by losing weight can thereby also reduce their risk of dying from heart attacks or strokes.
(C) Smokers, who tend to be leaner than nonsmokers, tend to have shorter life spans than nonsmokers.
(D) The normal deterioration of the human immune system with age can be slowed down by a reduction in the number of calories consumed.
(E) Diets that tend to lead to weight gain often contain not only excess fat but also unhealthful concentrations of sugar and sodium.

IMO C. The study found that lean people's life expectancy is not as great as that of big people. the current study says otherwise. if noth of them has to be true then if the leaner people of first people were smokers and life expectancy was less b'coz of their smoking habbut then bith the studies do not contradict each pther.

I'm going to have to go with C. It explains why people that stay thinner live shorter lives.

What is the OA?

C
The other choices do not link the facts in argument
With what about other components that make up the body - are they heavier or lighter. C is a lot clearer

if A then the smaller muscle percentage could be because of more fat thus the paradox isn't then resolved. but maybe i don't know what i'm talking about and it is A.

IMO C

If C is true, that weight gainers lived longer was not due to the weight gain itself, but rather to the absense of smoking.
On the other hand, the people who did not gain weight were smokers. None of the other choices resolves the discrepancy/paradox.

I think C - none of the others seem to resolve the paradox. They seem to tell us why reducing weight leads to a longer life span.

Can you share the OA, please?

I can put this argument as - Why weight gain causes problems in some and not in others?

Ans - (E) Diets that tend to lead to weight gain often contain not only excess fat but also unhealthful concentrations of sugar and sodium.

IMO : E
