Q9 Single choice

A study of young and middle-aged men in the United States has found that the men whose diet was high in saturated fat also had a high amount of blood cholesterol. In another experiment, when the blood cholesterol level of laboratory rabbits was raised by feeding them exclusively on cholesterol, fat deposits formed in their blood vessels. Similar fat deposits are found in human patients of heart disease. Therefore, to reduce the occurrence of heart disease, people should reduce their dietary consumption of saturated fat.

Each of the following, if true, weakens the above argument EXCEPT:

A
The bodily reactions of animal models to internal or external stimulants are often poor predictors of the reactions of the human body to the same stimulants.
B
The per capita consumption of saturated fat in the United States has decreased by 27 percent since 1970 while the occurrence of heart disease in the country has increased by 400 percent in the same period.
C
An analysis of studies done on more than 600,000 men and women has established that blood cholesterol is inversely associated with the risk of death from infectious respiratory and digestive diseases.
D
A study that covered more than 10,000 individuals has found no relationship between the amount of blood cholesterol and the occurrence of heart disease.
E
In a study where the dietary saturated fat consumption of young and middle-aged American women was three to seven times higher than normal, the blood cholesterol level remained unchanged.
