那么按照你列示的推理顺序 D) causes B)=> the foods increases the risk of heart attck.

sdcar2010

Yeah.  That's why E weakens the conclusion that A) causes B).

A hidden condition is that B), or high cholesterol, equals higher risk of heart attack.

sdcar2010

The stimulus says "high blood level of cholesterol, which is a factor increasing risk of heart disease."
