27. These days, drug companies and health professionals alike are focusing their attention on cholesterol in the blood. The more cholesterol we have in our blood, the higher the risk that we shall die of a heart attack. The issue is pertinent since heart disease kills more North Americans every year than any other single cause. At least three factors---smoking, drinking, and exercise—can each influence levels of the cholesterol in the blood.

Which one of the following can be properly concluded from the passage?

A.   If a person has low blood cholesterol, then that person’s risk of fatal heart disease is low.
B.   Smoking in moderation can entail as great a risk of fatal heart disease as does heavy smoking.
C.   A high-cholesterol diet is the principal cause of death in North America.
D.   The only way that smoking increases one’s risk of fatal heart disease is by influencing the levels of cholesterol in the blood.
E.   The risk of fatal heart disease can be altered by certain changes in lifestyle.
答案 E

C为什么不对啊！！！！！明明文中说了heart disease kills more North Americans every year than any other single cause

题干：因为每年北美死于心脏病的人比其他原因都高。胆固醇越高，死于心脏病的几率越高。抽烟，喝酒和锻炼能影响血液中胆固醇含量。

C饮食中高胆固醇是主要致死的原因。楼主注意题干说的是抽烟喝酒和锻炼影响胆固醇，没有说吃东西会，不能根据自己的常识来做题，信息严格按照题干来·~

E通过改变生活方式来改变致命心脏病的风险。因为抽烟，喝酒和锻炼能改变胆固醇，进而降低心脏病风险~
