题目信息

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.

原文说S会导致心脏病但是吃红酒能减少发病机率美国人吃S的量和法国人一样但是因为法国人红酒喝的比较多所以心脏病发病率低但是最近美国人喝红酒的差量和法国人正有相减少的趋势但是心脏病发病率却没怎么变问加入什么条件合适

A这个比较的对象原文没说过比较对象错误肯定杀选项

B过去30年美国吃S的量基本不变但法国有的地方却在上升这选项说的内容和原文相关可以先留下但这选项让我读起来不是太舒服因为这个选项不仅有方向上的问题法国局部上升又怎么能解释原文呢而且美国的S不变而法国有些地方的S相比这个比较对象是不是不太好

C说的是美国人的喝酒习惯这个和原文没什么关系吧

D说了个吸烟的问题看似无关但立刻添加了一句话which can also contribute to heart disease将与原文又相连在了一起但是方向又错了无法回答原文

E说的是法国年轻人中喝红酒量下降但是心脏病只有在中年才会体现这不仅说到了量还和病相关而且方向是对的不仅说量下降还说得病率现在不会有什么变化
