Scientists investigating a rare metabolic disorder hypothesized that obesity was a predisposing factor in the development of the disease. A study of twenty patients found that, on average, the patients were close to the normal weight for their height.

Before concluding that obesity is not a predisposing factor, the researchers would find the answer to which of the following questions most useful?

A. Are the patients above or below normal height?
B. Were any of the patients underweight when the disorder was diagnosed?
C. Does weight loss reduce the severity of the symptoms?
D. Have the patients always been close to the normal weight for their heights?
E. How many of the patients had obese parents?
It takes time and effort to explain, so if my comment helped you please press Thanks button :)



Just because something is hard doesn't mean you shouldn't try,it means you should just try harder.

Hey guys,
The OA is D.
Scientists investigating a rare metabolic disorder hypothesized that obesity was a predisposing factor in the development of the disease. A study of twenty patients found that, on average, the patients were close to the normal weight for their height.

Before concluding that obesity is not a predisposing factor, the researchers would find the answer to which of the following questions most useful?

A. Are the patients above or below normal height?-Study shows close,above or below is irrelevant.
B. Were any of the patients underweight when the disorder was diagnosed?
C. Does weight loss reduce the severity of the symptoms?-No connection of symptoms in the study.
D. Have the patients always been close to the normal weight for their heights?-In the passage it is given "A study of twenty patients found that, on average, the patients were close to the normal weight for their height."
This statement supports the conclusion of the study .

E. How many of the patients had obese parents?-No genetic relation given.
