求助一道GWD6-Q20

GWD6-Q20:

Five years ago, as part of a plan to encourage citizens of Levaska to increase the amount of money they put into savings, Levaska’s government introduced special savings accounts in which up to $3,000 a year can be saved with no tax due on the interest unless money is withdrawn before the account holder reaches the age of sixty-five.Millions of dollars have accumulated in the special accounts, so the government’s plan is obviously working.

Which of the following, if true, most seriously weakens the argument?



A.A substantial number of Levaskans have withdrawn at least some of the money they had invested in the special accounts.

B.Workers in Levaska who already save money in long-term tax-free accounts that are offered through their workplace cannot take advantage of the special savings accounts introduced by the government.

C.The rate at which interest earned on money deposited in regular savings accounts is taxed depends on the income bracket of the account holder.

D.Many Levaskans who already had long-term savings have steadily been transferring those savings into the special accounts.

E.Many of the economists who now claim that the government’s plan has been successful criticized it when it was introduced.

我选了A，答案是D。求解释~~~

题目讨论的是“是否special savings accounts能够增加saving”
有个关系希望你能读出来
savings（设为X）=计划中的special savings（设为Y） + 原来的long-term savings （设为Z）
想要X增加，在告知Y增加的同时，不能让Z减小
D选项就是在说Y的增加是Z的减小造成，对X，即savings的增加构成削弱

至于A，是经典的干扰选项，因为题目讨论的是“是否special savings accounts能够增加saving”

至于人们是不是在存到special accounts把special accounts的存款再取出来，只是计划中的一个细节的讨论，不不影响结论“是否special savings accounts能够增加saving”的评价，所以不在讨论范围的里。

典型的无关选项，这个选项设计的很有迷惑性，我对出题人表示下尊敬。
对于这样手段——目的型的题目，不要在意手段中的细节，而应把重点关注在其对目的的影响程度上。


不妨我退一步，来讨论下这个无关选项，这么理解：人们把special accounts的存款再取出来，恰恰证明了人们存了钱，如果说它相关的话，也构成支持选项。因为我们只关心这个计划能不能让人们去存钱。
