91. Businesses are suffering bacause of a lack of money available for development loans. To help businesses, the government plans to modify the income-tax structure in order to induce taxpayers to put a larger portion of their incomes into retirements savings accounts, because as more money is deposited in such accounts, more money becomes available to borrowers.
Which of the following, if true, raises the most serious doubt regarding the effectiveness of the government's plan to increase the amount of money available for development loans for business?
A. When levels of personal retirement savings increase, consumer borrowing always increases correspondingly.
C. Even with tax incentives, some people will choose not to increase their levels of retirement savings.
OG答案为A，理由是由于多出的退休金需要同时面对随之而来的消费者贷款的需求，而不能单一地满足商业贷款需求，由此计划的有效性下降。
C错的原因是因为只是SOME people，而不是most people没有增加退休金的存款，所以不会影响计划的有效性。
请问：是否some所表示的数量真的非常非常少吗？即使非常非常少，但必然也会对计划的有效性产生影响。而A中产生的消费者贷款的需求的程度也未提及，所以无法判断它对有效性影响的程度。那么这时如何判断A比C more SERIOUS呢
题中用了induce(to persuade someone to do something, especially something that does not seem wise)，有这层含义在，表示some people完全有理由拒绝增加退休金存款，直接打击了计划的有效性啊。 |
