对于逻辑机经，不要太重视选项，因为考试有可能将正确选项变体为错误选项。
给大家一个prep与GWD变体选项的例子。--越是碰到机经题，越是要好好分析选项
prep：In order to improve the long-term savings rate of its citizens, Levaska’s government has decided to introduce special savings accounts.  Citizens can save up to $3,000 a year in special accounts without having to pay tax on the interest, unless they withdraw money from the account before they reach the age of sixty-five.  If they do withdraw any money before that age, they have to pay tax on the accumulated interest and a penalty.

Which of the following, if true, most seriously threatens the success of the government’s plan?

A. The banks and financial institutions where the special accounts will be held lobbied hard for their introduction.
B. Nearly all workers in Levaska can already save money in tax-free accounts through their workplace.
C. For the past ten years, Levaskans have been depositing an ever smaller percentage of their income in long-term savings.
D. Many Levaskans continue to work beyond the age of sixty-five.
E. In certain circumstances, such as a serious illness, the government plans to waive the penalty on early withdrawals from the special accounts.-Strengthen

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special savings accounts in which up to $3,000 a year can be saved with no tax due on the interest unless money is withdrawn before the account holder reaches the age of sixty-five.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A.        A substantial number of Levaskans have withdrawn at least some of the money they had invested in the special accounts.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