The importance of a well-balanced diet high in fiber and low in saturated fat is understood by most shoppers in Arcadia County. Moreover, food Line nutrition labels clearly display important nutritional information. As a result, sales of high-fiber foods in Arcadia County have risen dramatically during the last decade, while sales of foods high in saturated fat have dropped by a similar magnitude. Even so, during the last decade the number of shoppers in Arcadia County who are overweight has increased substantially. The more the residents of a city exercise, the lower the average number of heart attacks in that city. Likewise, the less the residents of a city exercise, the greater the average number of heart attacks in that city. Therefore, people who wish to reduce the chance of suffering a heart attack should exercise more.
Which of the following, if true, most seriously undermines the argument?
A. Heart attacks are a common cause of death in cities with high exercise rates.
B. The cities with low exercise rates are often those with the highest standards of living.
C. A particular resident of a city whose population has a high exercise rate may not exercise at all.
D. The cities with high exercise rates are also the cities with the lowest number of cigarette smokers.
E. The differences in exercise rates among cities often result from the availability of conveniently located gyms.

This weaken question addresses the conclusion of the passage, which states that "people who wish to reduce the chance of suffering a heart attack should exercise more." The argument presents a causal pattern, assuming that the correlation between average number of heart attacks and exercise rates is not a coincidence. If this correlation is a coincidence, then the argument's conclusion is weakened. Choice (A) can be eliminated as out of scope, as the passage discusses raising and lowering the risk of heart attack not whether heart attacks are a common cause of death. Choice (B) can be eliminated, as high standards of living cannot be supported to have an impact on the conclusion. Choice (C) is a reversal, as a resident who personally has a high exercise rate may not see a benefit from additional exercise, but one who does not exercise is more likely to see a benefit from exercise. Choice (E) is out of scope, as the reason for different exercise rates does not impact the conclusion. The correct answer is (D).
