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special savings accounts in which up to $3,000 a year can be saved with no tax due on the interest unless money is withdrawn before the account holder reaches the age of sixty-five.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A substantial number of Levaskans have withdrawn at least some of the money they had invested in the special accounts.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.
A项 withdrawn at least some of the money,语意上倾向于相对于存进去的钱,withdrawn的前很少,所以这个计划还是能起作用的
D项 是说存进special account的钱原来就在银行里,只不过是普通账户,所以居民put into saving的钱总数并没有增加,只是从一个账户换到了另一个账户,计划不起作用
