Please explain why answer choice E is correct
on June 22, 2015
We are told that people with type B lipid profile are at much greater risk of heart disease than those with type A lipid profile.
After the experiment we know that the type A lipid profile volunteers showed no benefit from the diet, and 40% of them shifted to type B profiles.
Well, we know that type B lipid profiles are at much greater risk of heart disease than type A lipid profiles. So, the 40% of type A profile volunteers that switched to B profiles actually raised their risk of heart disease after the experiment, i.e. after having been put on the low-fat diet.
Thus, answer choice (E) must be true according to the information in the passage: "For at least some of the volunteers in the experiment, the risk of heart disease increased after having been put on the low-fat diet."
Hope that clears things up! Please let us know if you have any other questions.
