Question

how does regular exercise affect the probability of developing heart disease?
a. it decreases the probability by 30 - 40%
b. it doubles the risk of heart disease
c. it has no effect on the probability
d. it increases the probability by 30%

Explanation:

Regular exercise is known to have beneficial effects on heart health. It helps in improving cardiovascular function, reducing blood pressure, improving lipid profiles, and enhancing overall metabolic health. These factors collectively lower the risk of heart disease. Option b is incorrect as exercise does not double the risk. Option c is wrong because exercise has a significant impact. Option d is incorrect as it increases the probability (which is opposite of what exercise does). Option a aligns with the known positive impact of exercise on reducing heart - disease risk.

Answer:

A. It decreases the probability by 30 - 40%
