Magoosh Official Explanation:
This argument has a relatively well-accepted conclusion: all people, and especially those at risk for heart disease, should eat a diet high in fresh fruits and vegetables. It's already a strong from familiarity, and we want to make it stronger.
(E) is the credited answer. If folks with heart disease who don't eat fruits and vegetables are much more likely to have heart attacks, then that is another huge piece of evidence in favor of the conclusion that fruits and vegetables are so important for heart health.
(A) is true but irrelevant. The fact that whole grains are also healthy give no additional evidence as to why fresh fruits and vegetables are so important.
(B) is entirely irrelevant. In our modern day and age, fruits and vegetables are shipped all over the world. One does not need to live close to a farm to have these as a regular part of one's diet.
(C) is true but also irrelevant. Smoking is bad, but this tells us nothing about why fresh fruits and vegetables are good.
(D) is too open-ended. To be vegetarian implies an entire lifestyle ---- for example, it has high correlations with yoga, meditation, time in Nature, eating organic, and a number of other factors that can affect heart health. We have no way of knowing whether it is very specifically the fresh fruits and vegetables in the diet of vegetarians that gives them edge in heart health. There are just too many factors in play to draw such a specific conclusion.
