标题: [求助]没问过的GWD-9-Q16

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.

这道题选E，为什么呢？NN能帮忙分析下么？

越看越糊涂了~~~

我也看了半天才明白。。。有单词不认识，哎。。

这题要解释的是这个矛盾：

The difference in regular red-wine consumption has been narrowing, but no similar convergence in heart-disease rates has occurred.

（法国和美国）红酒消费量的差别变小了（前面说因为法国人消费量多过美国，所以得心脏病的人少），但是两国心脏病的发病率却没有同等的减少。

E选项说法国年轻人的红酒消费量急降（这可以引起两国红酒消费量差别变小），但是heart disease typically does not manifest itself until middle age.到中年才会有心脏病的症状出现。（法国喝红酒的人群结构有变化，但是没有影响到患心脏病的人群，所以法国美国心脏病的发病率没变化）

那B选项呢？也可以是因为法国的fat是increase 从而抵消影响的呀

题目中说了，consumption of saturated fats is currently about the same，因此，已经明确了在现在时点，两个国家的脂肪消耗一样的。因此是否是B中的过去30年怎么怎么样，没有影响。而且B是somewhat，也证明了没什么影响。

想了半天终于发现自己一上来思路就错了

结论是美国和法国喝红酒的量都差不多了.但心脏病率差距没有同样的减少
思路一:
法国人心脏病率不变(假设10%),美国人即使喝了更多的红酒还是那么多心脏病率(假设20%)
所以我就从选项中拼命找关于美国的选项...
思路二:
由于某些原因,法国人心脏病率上升了(假设从10%-->20%)
而美国人喝了更多的红酒心脏病率下降了(假设20%-->10%)
因此差距还是10%
要从选项中找关于法国的某些原因

其实就算fat在法国增多很多我们也不知道fat的作用是Increase heart disease还是下降。以常理来说是上升心脏病，那样的话两个国家的gap应该是减小了，可结论是gap没变，所以不选B.
