The premises are higher cholesterol in the blood will lead to more chance of getting heart attack, and smoking, drinking and exercising can influence the level of the cholesterol > reduce chance of getting blood disease. So answer is E

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 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 disease can be altered by certain changes in lifestyle

E is a solid trap answer for nay other question. Think for a second just because ecxccersise can help reduce heart attacks does that mean it can help cancer too it's such a leap in logic.

Why is heart attack not the principal cause of death in NA is this not mentioned in the text?

A uses the common fallacy A --> B doesn't mean that not A --> not B.
It could also be seen logically that there could be other reasons for heart disease to persist even if the person has low cholesterol, hence not true that low cholesterol will lead to low heart disease.

The best conclusion is E) The risk of fatal disease can be altered by certain changes in lifestyle.
The passage states that smoking, drinking, and exercise can influence cholesterol levels, and high cholesterol is linked to an increased risk of fatal heart disease.
This means that lifestyle changes related to these factors can affect a person's risk.

Explanation of why other options are incorrect:

A) If a person has low blood cholesterol, then that person's risk of fatal heart disease is low.
While low cholesterol generally lowers the risk, the passage doesn't make this a direct correlation. It only states that more cholesterol means higher risk, not a guarantee if one is lower risk.

B) Smoking in moderation can entail as great a risk of fatal heart disease as does heavy smoking.
The passage does not compare the risk of moderate vs. heavy smoking. It only states that smoking can increase the risk.

C) A high-cholesterol diet is the principal cause of death in North America.
The passage does not say diet is the principal cause, just that it's a factor. It also doesn't specify that a high-cholesterol diet is the only factor.

D) The only way that smoking increases one's risk of fatal heart disease is by influencing the levels of cholesterol in the blood.
The passage only says smoking influences cholesterol levels, but it doesn't say it's the only way smoking increases risk. Other factors could be involved.
