Question

much lower heart rate while jogging than a non - athlete. it is common for an athletes heart rate, while jogging, to be lower than a sedentary persons heart rate at rest. this is because the athletes heart has been trained to function more efficiently. it can pump more blood with each heartbeat than that of someone who does not exercise. for this reason, the heart is less likely to have a buildup of fatty deposits. fatty deposits can lead to heart disease, which is a leading cause of death in the united states. do it! a lower heart rate often ______ a healthy heart. a disrupts b indicates c disguises d prevents

Explanation:

To solve this, we analyze the context. The passage explains that an athlete's lower heart rate (while jogging) is due to a more efficient heart, which is healthy. We then analyze each option:

• Option A: "disrupts" means to interfere with, which doesn't fit as a lower heart rate (from training) doesn't disrupt a healthy heart.
• Option B: "indicates" means to show or suggest. A lower heart rate (from efficient heart function) shows a healthy heart, which matches the context.
• Option C: "disguises" means to hide, which is not relevant here as a lower heart rate isn't hiding a healthy heart.
• Option D: "prevents" means to stop from happening. A lower heart rate doesn't prevent a healthy heart; rather, a healthy (trained) heart leads to a lower heart rate.

Answer:

B. indicates
