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special savings accounts in which up to $3,000 a year can be saved with no tax due on the interest unless money is withdrawn before the account holder reaches the age of sixty-five.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?
GWD4-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special savings accounts in which up to $3,000 a year can be saved with no tax due on the interest unless money is withdrawn before the account holder reaches the age of sixty-five.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A. A substantial number of Levaskans have withdrawn at least some of the money they had invested in the special accounts.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.
我觉得A\D的错误是一样的,都是只考虑了整体中的部分情况。如果一定要在A\D中选一个,选D是因为millions of dollars have accumulated in the special accounts这句紧贴结论,作为提示,“大量的钱在特殊账户中累计”,所以储蓄总量就多了?如果特殊账户里的钱多了,但别的账户里钱少了,总量不一定增加
我也觉的这道题有争议,本题是因果推理,因为有million 的dollars已经存在 special account上边了,所以政府计划(增加居民存款)是成功的。 我们要削弱要么攻击推理本身,要么攻击因,就是miilion dollars存在sp上了并没有达到政府的计划,其中一个表象就是D所描述的,存款只是发生了转移,并没有净增加,sp增加的只是表象。抓住steadliy transfer优于A中的at least some。所以我认为D优于A。
