逻辑，A为什么被排除了

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special savings accounts in which up to $3,000 a year can be saved with no tax due on the interest unless money is withdrawn before the account holder reaches the age of sixty-five.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 A substantial number of Levaskans have withdrawn at least some of the money they had invested in the special accounts.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.

正确答案是D

原文说“with no tax due on the interest unless money is withdrawn before the account holder reaches the age of sixty-five”
A说有些人取出一些钱，所以weaken，为什么A被排除了

前提：政府希望市民多存钱，就推出了一个优惠政策（政策的内容。。。。）
前提：millions of money 存进了这个account中
结论：政府的措施是有效的。

要明确政府的目的是：to encourage citizens of Levaska to increase the amount of money they put into savings

你用A攻击前提，无关痛痒，不影响政府鼓励的措施

我是这样想的，CR描述的情况千变万化，其中有一类题目是，告诉你A事件，然后导致了B结果，要weaken的办法就是证明存在一个C事件也可能造成B结果，不用纠缠题义中的细节，就能一下排除选项了。

恩，这样做题好像更快，更直接
