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special savings accounts in which up to $3,000 a year can be saved with no tax due on the interest unless money is withdrawn before the account holder reaches the age of sixty-five.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A.      A substantial number of Levaskans have withdrawn at least some of the money they had invested in the special accounts.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

这题我也做错了，补充一下，我再读了一下选项A，发现有这么一个问题：

at least some of the money they had invested in the special accounts.

但是文中并没有说some of money到底是多大？如果这些money的取出比较少的话，是不是就不足以削弱？而整个的存储其实还是增加了，不受这少量的影响呢?
