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special savings accounts in which up to $3,000 a year can be saved with no tax due on the interest unless money is withdrawn before the account holder reaches the age of sixty-five.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?

1. A substantial number of Levaskans have withdrawn at least some of the money they had invested in the special accounts.
2. 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.
3. The rate at which interest earned on money deposited in regular savings accounts is taxed depends on the income bracket of the account holder.
4. Many Levaskans who already had long-term savings have steadily been transferring those savings into the special accounts.
5. Many of the economists who now claim that the government’s plan has been successful criticized it when it was introduced.（d）

我觉得要 increase the amount of money they put into savings，有两个办法一是使人多存钱，二是使人少取钱。d选项是针对一来weaken的，而a选项也针对二weaken了。并且原文中也说了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savings accounts in which up to $3,000 a year can be saved with no tax due on the interest unless money is withdrawn before the account holder reaches the age of sixty-five.似乎更看重法二，所以我看到a就选了。请nn指教

问一下自己,如果A成立,政府的目的达到了吗?

你会觉得就算拿出一点钱,政府眼要增加存款的目的也已经达到了.

1:是选最优,想一下A和D比起来哪个更能削弱.

2:A中at least some of,不拿全部就达到目的
