Preventing Heart Disease
Heart disease is a life-threatening condition that kills millions of people every year. In fact, heart disease is the number one killer of human beings worldwide; over thirty percent of deaths every year are due to some form of cardiovascular disease. Although there are many different types of medications and surgical procedures that can treat heart disease, prevention is the most important factor in reducing the number of deaths.
Proper nutrition is important in preventing heart disease. The recommended diet for a healthy heart is low in saturated fats, cholesterol, salt, and refined sugar. The diet should be high in fiber, whole grains, fruits, and vegetables.
Smoking and excessive alcohol consumption should be avoided. Smoking increases the risk for heart disease at least ten-fold, and drinking too much alcohol can raise the levels of some fats in the blood and lead to high blood pressure and increase the risk of cardiovascular damage.
Lack of physical exercise can also make a person more likely to suffer from heart disease. Participating regularly in aerobic exercise, which can include walking, jogging, dancing, or swimming significantly reduces the risk of heart disease.
Another contributor to heart disease is stress. Constant stress can expose your body to persistently elevated levels of the stress hormones cortisol and adrenaline. High levels of these hormones can increase blood pressure and damage artery walls. Engaging in yoga, meditation, or other relaxation techniques can be helpful in reducing stress and lowering the risk of heart disease.
Question: What can be inferred from a person with constantly elevated stress levels, according to the passage?

In paragraph 5, the author explains that high levels of cortisol and adrenaline, caused by constant stress, can damage artery walls. Therefore, the information in this option could be inferred.
The person will need to engage in yoga and meditation. Although yoga and meditation is listed as being able to help those who experience high levels of stress, it is incorrect to infer that the person needs to undergo these practices.
There is not enough cortisol or adrenaline in the system is incorrect. The opposite of this is true, as stated in paragraph 5. When a person is constantly under elevated stress levels, he or she will likely have high cortisol or adrenaline levels in the system.
They are not at high risk for heart disease is incorrect. The opposite of this is true, as is stated at the beginning of paragraph 5: "another contributor to heart disease is stress". Therefore, this is incorrect.
