标题: 請高手指點一下

A diet high in saturated fats increases a person’s risk of developing heart disease. Regular consumption of red wine reduces that risk. er-capita consumption of saturated fats is currently about the same in France as in the United States, but there is less heart disease there than in the United States because consumption of red wine is higher in France. The difference in regular red-wine consumption has been narrowing, but no similar convergence in heart-disease rates has occurred.

Which of the following, if true, most helps to account for the lack of convergence noted above?

Consumption of saturated fats is related more strongly to the growth of fatty deposits on artery walls, which reduce blood flow to the heart, than it is to heart disease directly.

Over the past 30 years, per-capita consumption of saturated fats has remained essentially unchanged in the United States but has increased somewhat in France.

Reports of the health benefits of red wine have led many people in the United States to drink red wine regularly.

Cigarette smoking, which can also contribute to heart disease, is only slightly more common in France than in the United States.

Regular consumption of red wine is declining dramatically among young adults in France, and heart disease typically does not manifest itself until middle age.

答案是E

我有點看不懂這句話

可否請高人指點一下它的中文意思??

红酒的消耗量在减少, 可是对应的心障病的比例确没有减少.
