The number of North American children who are obese-that is, who have more body fat than do 85 percent of North American children their age-is steadily increasing, according to four major studies conducted over the past 15 years.
If the finding reported above is correct, it can be properly concluded that
(A) when four major studies all produce similar results, those studies must be accurate
(B) North American children have been progressively less physically active over the past 15 years
(C) the number of North American children who are not obese increased over the past 15 years
(D) over the past 15 years, the number of North American children who are underweight has declined
(E) the incidence of obesity in North American children tends to increase as the children grow older
[spoiler]The OA given is Op C, i have some doubt regarding the reasoning given for Op C. The reasoning given is: the no of children who are obese is increasing as given in Op C plus writer assumes that total no of children also increasing and hence obviously the no of children who not obese is also increasing. Now, i have some doubt in the RED color part...is it really really necessary that "total no of children also increasing", i might be thinking illogically but please clear, isn't it possible that total pop. remains same, may be because of, for example, say a huge no of children who are not obese expired because of some disease etc. if at all that case will happen then i think Op C will not hold as a must be true statement.[/spoiler]
