GWD 9-16 红酒和心脏病的问题，不明白呀，HELP!

Echoxlx

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.

不明白为什么选E啊？请大家指点迷津！

E经常喝红酒得年轻人少了，到了中年，这些年轻人变成了心脏病高发人员

所以结论出现，虽然喝红酒得差距在减少，但是得病得情况没有改善

A无关

B和文章相背

C美国人再增加红酒量，那么文章中得红酒差距narrow就不成立了

D only过于绝对，直接排除。

请问：but no similar convergence in heart-disease rates has occurred.这句话什么意思？

谢谢！

以下是引用floraxycn在2007-3-30 10:24:00的发言：

文章的结论是红酒能够减少心脏病发病率

该句话前半句是The difference in regular red-wine consumption has been narrowing

美法两国红酒的消费的差异减小,按道理心脏病发现率也应该减小,而实际上不是

因此这句话的意思是:但是却没有类似的趋势发生在心脏病率上

另外,我觉得选项E的意思是年轻人红酒消费量急剧减少,但是心脏病一般来说30岁以后才会体现出来,因此即使目前红酒消费量减少了,也不能马上就能观察到心脏病的减少(如果红酒真的有效果,也是在若干年以后才能体现)

Agree with 遥远的绿洲

当年的表达有点偏了，what a mess
