Economist: Some policymakers believe that our country’s continued economic growth requires a higher level of personal savings than we currently have. A recent legislative proposal would allow individuals to set up savings accounts in which interest earned would be exempt from taxes until money is withdrawn from the account. Backers of this proposal claim that its implementation would increase the amount of money available for banks to loan at a relatively small cost to the government in lost tax revenues. Yet, when similar tax-incentive programs were tried in the past, virtually all of the money invested through them was diverted from other personal savings, and the overall level of personal savings was unchanged.
15. The author criticizes the proposed tax-incentive program by
(A) challenging a premise on which the proposal is based
(B) pointing out a disagreement among policymakers
(C) demonstrating that the proposal’s implementation is not feasible
(D) questioning the judgment of the proposal’s backers by citing past cases in which they had advocated programs that have proved ineffective
(E) disputing the assumption that a program to encourage personal savings is needed

答案是A，D为什么不对呢？

The first half is D is right. From "...in which they advocated..." it is wrong. In the question it says" similiar programs". We do not know if the backers "advocate" those programs or not.

A is right. The premise of the argument is that "...its implementation would increase the amount of money available for banks to loan ...". The author then argues that the increase in fund in savings account is from other personal savings, so that the overall personal savings will not change. So the amoun tof money available will not change.

Pay particular attention to look-like choices such as D. It is too much like an answer and you need to pay extra attention to it.

我认为D错在最后一部分，画蛇添足。
(D) questioning the judgment of the proposal’s backers by citing past cases in which they had advocated programs （that have proved ineffective ）
there is no evdience to prove that such programs are ineffective. In fact, tax-incentive program indeed keep money in account for a longer time and indirectly benefit loans, but it just cannot increase the total amount of money.
所以，d 选项是错误的。
