请教一个OG的

91. Businesses are suffering because 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 individual taxpayers to put a larger portion of their incomes into retirement 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 businesses?

(A) When levels of personal retirement savings increase, consumer borrowing always increases correspondingly.
(B) The increased tax revenue the government would receive as a result of business expansion would not offset the loss in revenue from personal income taxes during the first year of the plan.
(C) Even with tax incentives, some people will choose not to increase their levels of retirement savings.
(D) Bankers generally will not continue to lend money to businesses whose prospective earnings are insufficient to meet their loan repayment schedules.
(E) The modified tax structure would give all taxpayers, regardless of their incomes, the same tax savings for a given increase in their retirement savings.

注意到increase the amount of money available，即supply，A的意思明显是demand上升了，怎么会削弱？

我会选A , 欢迎指出错误. 楼主应该是误会consumer borrowing 就是上面的 business loans for development?

结论是: goverment should plan larger XXXX account

前提: more money in XXXX account,more money will aviable to borrowers.

问题:选weaken

基本思路: 如果这个前提不可行或者无意义,则结论seriously weaken.

A  Consumer borrowing 增加,则 Business loan 不一定增加, no gurantee for more money avaible to borrowers. 削弱. 

    当然,我assume  了conusmer borrowing + business borrowing = total loans.

B  first year of plan? 无关,错

C. "tax incentive" 与 "induce" 的是否算有关,先不管.it says "some people". 没有削弱. as long as the total fund gets bigger in the end and more loans can be offered to business, it doesn't even matter whether or not there are some people didn't accept the changes in the first place...

D. bankers? 无关推理,错

E. how ? 无关整个推理,错
