Read the passage and then answer the question.

Blood pressure is an important measure of heart health. What exactly is blood pressure, and why is it important?

An answer to the first question requires understanding how the heart beats. When you rest, your heart beats about 60 to 70 times a minute. Each time your heart beats, it pumps blood into the arteries. At these moments, your heart is pushing blood. Between beats, your heart relaxes. It does not push blood. Your blood pressure is a measurement of these two states of your heart. It is shown as a fraction, such as $120 / 80$. The top number represents the state of your heart during pushes. The bottom number is your heart when it is not pushing.

A trained medical professional can measure your blood pressure using an instrument called a sphygmomanometer. If your blood pressure is high, your doctor will do other tests to determine why. To lower your blood pressure, the doctor may recommend changes in lifestyle. These include getting regular exercise and eating healthy foods.

A. A blood pressure of $120 / 80$ is better than a blood pressure of 120/70.

B. High blood pressure is a sign of possible heart problems and may require require lifestyle changes.
