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）
(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.
按照答案E的说法，的确可以增加存款。但是题目问的是weaken the argument，E里面根本就没有提到前面所谓的investing in research and development ，因为存款增加并不意味着投资增加。比如中国人的存款多得很，但是投资的却很少。那么E根本就与argument无关，只是削弱了结论。这该如何解释？
