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special savings accounts in which up to $3,000 a year can be saved with no tax due on the interest unless money is withdrawn before the account holder reaches the age of sixty-five.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A substantial number of Levaskans have withdrawn at least some of the money they had invested in the special accounts.
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.
The rate at which interest earned on money deposited in regular savings accounts is taxed depends on the income bracket of the account holder.
Many Levaskans who already had long-term savings have steadily been transferring those savings into the special accounts.
Many of the economists who now claim that the government's plan has been successful criticized it when it was introduced.
要选出使计划不成功的一项->存款不增加
A. irrelevant
B. irrelevant
C. irrelevant
D. 公民转移存款，总存款并没有增加。
一定要清楚这个arguement/plan的目标和方法分别是什么，以及他们之间的关系，从而可以主动推理。
premise：special account—no tax, unless withdraw under 65
Conclusion: The plan is working , and it increases the amount the citizens put into saving
CQ1-方案可行性问题
问题：哪个说明政府的计划并没有鼓励储蓄。
D，Many Levaskans who already had long-term savings have steadily been transferring those savings into the special accounts.很多已有长期储蓄账户的人把账户里的钱转到了特殊账户。所以，特殊账户里有很多钱并不表示政府的政策鼓励了储蓄率的增加。
choice d, 许多人把钱从长期储蓄账户里面转移到特别账户。correct，这部分人的总储蓄金额没有增加
plan 的题一定要看好plan 的目的
但D选项说明有人把原来就存在银行的钱拿出来放进special account里，也就是说总量不变只是转移了，所以weaken
答案：Many Levaskans who already had long-term savings have steadily been transferring those savings into the special accounts. 即：很多人只是转账过去special account， 所以 amount of money 还是没有增加。
D. transferring 表明总量并没有增加
B.是说能否获益，无关选项
B项 许多人已经有长期存款账户，不能利用政府的special account。并不符合前提中提到这部分人，所以没能阻止前提推出结论
D项 许多人从自己已有长期存款账户中取钱转移到special account，最终并不能够使得长期存款增加。有果无因
因：政府的tax刺激计划
B: 不管受没受惠，只要存款变多，方案就可行。
