A recent study suggests that regular exercise improves the health of person's heart and cardiovascular system. Five years ago, people under the age of 60 accounted for 50 percent of the people who had suffered one or more heart attacks. Today, people under the age of 60 account for only 40 percent of the people who have suffered one or more heart attacks. The same study shows that people under the age of 60 exercise more regularly today than they did 5 years ago, while the exercise habits of people aged 60 and over have remained the same.
Which one of the following most strengthens the argument?
A. Some people over the age of 60 exercise as much or more than do people under the age of 60.
B. The proportion of the population aged 60 and over has remained constant over the last five years.
C. The use of cholesterol-lowering drugs has reduced the frequency of heart attacks among all age groups.
D. People aged 60 and over are generally less capable of strenuous exercise than are people under the age of 60.
E. A number of factors, such as nutrition and stress levels, affect the incidence of heart attacks.
