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" />

虽然A--B,但是并不代表 否A--否B

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。。。
