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. proposed changes to the tax code could involve strict limits on the deductability of interest, and increased allowance for research.

b. 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.

答案选b. a.是什么意思啊，为什么不对呢，能不能解释一下
