【求助】逻辑大全上的一道题

3. Economies in which a high percentage of resources are invested in research and development show greater growth in the long run than do those in which resources are channeled into consumption. Japanese workers spend a higher percentage of their income investing in research and development than do American workers.
To grow as fast as Japan has in the past three decades, the United States must change the tax code in order to encourage savings and investment and discourage debt.
Which of the following, if true, tends to weaken the argument?

(A) Japanese research is more focused on consumers than is research by American firms.
(B) Class mobility, highly valued in American culture, is encouraged by a growing rather than a stagnant economy.
(C) Studies have shown that countries with high consumption rates prosper in the short run.
(D) Proposed changes to the tax code could involve strict limits on the deductability of interest, and increased allowance for research.
(E) Because a decreasing percentage of the United States is under 40, an age when savings are traditionally low, the savings rate will increase without changes to the tax code.

OA是E。我选了D。
有点不太明白前面的条件明明是讲研究的重要性，后面就讲存款与负债。
大全好难呀，正确率从来没超过70%

这句话的意思是会储蓄的美国人且年龄在40以下的越来越少了，这个年龄段的人存钱的本来就少，就算不改变税 ...

终于看明白了。E中的age我给翻译成时代了。。。
谢谢啦。我好像下载了一些视频，一会儿去看看。
视频总是看的时候挺明白，一做题就又不会了。

这句话的意思是会储蓄的美国人且年龄在40以下的越来越少了，这个年龄段的人存钱的本来就少，就算不改变税收代码储蓄也会增加的。

最后一句话明显与原文的结论相反了。做CR最好是用排除法，五个选项中明显只有E中有税收代码和储蓄。

GWD的在线逻辑课程你听过吗？我觉得还蛮有用的，谢谢你的分享~！

这道题目，我也认为选择E喔。

谢谢。题明白了，但选项E里面decreasing percentage of the United States讲的是什么的百分比呀？(E) Because a decreasing percentage of the United States is under 40, an age when savings are traditionally low, the savings rate will increase without changes to the tax code.

这道题目，我也认为选择E喔。

题目是问下面哪一个选项会削弱上文中的总结。上文中的总结：美国政府必须通过修改税收代码来鼓励人们储蓄和投资，让人们减少负债。

选项D表示修改税收代码对利率有影响，能够提高研发的补贴。这感觉对文章中的总结不太相关
选项E则说明美国不修改税收代码储蓄会自然提高 ，这感觉原文中的总结不太正确，有削弱的作用。
