Q19:
A diet high in saturated fats increases a person’s risk of developing heart disease. Regular consumption of red wine reduces that risk. Per-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?

A. 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.
B. 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.
C. Reports of the health benefits of red wine have led many people in the United States to drink red wine regularly.
D. Cigarette smoking, which can also contribute to heart disease, is only slightly more common in France than in the United States.
E. Regular consumption of red wine is declining dramatically among young adults in France, and heart disease typically does not manifest itself until middle age.
Answer: E

第一個想問的是這題是要解釋哪邊的差異？
是說為什麼紅酒消耗量越趨近相同，但是為什麼heart disease發生率卻沒縮小嗎？

這題是解釋題(Explanation), 所以要先找出"矛盾"點!

題目說, 喝紅酒可以降低心臟方面的疾病, 美法兩國在飲用紅酒量的差異正在縮小, 卻沒見到兩國在心疾病的罹患率在接近。
問為什麼會這樣?

E說, 法國的紅酒消費的增加主要來自年輕人, 然而心疾病主要是會在中年以後在發生!
所以　E 就解釋了為什麼為什麼法國的紅酒消費增加　卻不見其心疾病的罹患率降低的原因,
因為　年輕人本來就不容易有此方面的疾病!!

希望有解答到你的問題
