逻辑两题，搞不明白

Three large companies and seven small companies currently manufacture a product with potential military applications.  If the government regulates the industry, it will institute a single set of manufacturing specifications to which all ten companies will have to adhere.  In this case, therefore, since none of the seven small companies can afford to convert their production lines to a new set of manufacturing specifications, only the three large companies will be able to remain in business.

Which of the following is an assumption on which the author’s argument relies?

1. None of the three large companies will go out of business if the government does not regulate the manufacture of the product.
2. It would cost more to convert the production lines of the small companies to a new set of manufacturing specifications than it would to convert the production lines of the large companies.
3. Industry lobbyists will be unable to dissuade the government from regulating the industry.
4. Assembly of the product produced according to government manufacturing specifications would be more complex than current assembly procedures.
5.  None of the seven small companies currently manufactures the product to a set of specifications that would match those the government would institute if the industry were to be regulated.

答案是E

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special savings accounts in which up to $3,000 a year can be saved with no tax due on the interest unless money is withdrawn before the account holder reaches the age of sixty-five.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 A substantial number of Levaskans have withdrawn at least some of the money they had invested in the special accounts.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

答案是B

第二个题我觉得选D,因为目的是增加总存款,把其他帐户的钱取出来寸到特殊帐户等于没变.

1. 大意:如果政府通过某法案,生产该产品的3大公司和睦相处小公司只有大公司活下来.

E:小公司产品不符合该法案要求,得出钱调整,since they can't afford, they can not survive.

2. D makes more sence to me for this question.
