标题: [求助]费费逻辑宝典27

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. fficeffice" />

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.

(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.

key is E

请问A错在哪里？

虽然A--B,但是并不代表否A--否B

所以more cholesterol -- higher the risk that we shall die of a heart attack并不推出low blood cholesterol--person’s risk of fatal heart disease is low.

适度吸烟和重度吸烟一样，都会引起致命的心脏病

虽然ABCD都不对，但是我觉得E有些牵强，怎么就突然冒出来了个lifestyle？

原文不是在讨论胆固醇啊，心脏病啊，其他致命的疾病吗？结论怎么来了个改变生活方式来降低得心脏病的几率？

求教。。。
