大全-2-5 大家帮我推下推理连接

大全-2-5.      The city’s public transportation system should be removed from the jurisdiction of the municipal government, which finds it politically impossible either to raise fares or to institute cost-saving reductions in service. If public transportation were handled by a private firm, profits would be vigorously pursued, thereby eliminating the necessity for covering operating costs with government funds.

The statements above best support the conclusion that

(A) the private firms that would handle public transportation would have experience in the transportation industry

(B) political considerations would not prevent private firms from ensuring that revenues cover operating costs

(C) private firms would receive government funding if it were needed to cover operating costs

(D) the public would approve the cost-cutting actions taken by the private firm（B）

(E) the municipal government would not be resigned to accumulating merely enough income to cover costs

怎么来的呢？

大全-2-17.    Mr. Lawson: We should adopt a national family policy that includes legislation requiring employers to provide paid parental leave and establishing government-sponsored day care. Such laws would decrease the stress levels of employees who have responsibility for small children. Thus, such laws would lead to happier, better-adjusted families.

Which of the following, if true, would most strengthen the conclusion above?

(A) An employee’s high stress level can be a cause of unhappiness and poor adjustment for his or her family.

(B) People who have responsibility for small children and who work outside the home have higher stress levels than those who do not.

(C) The goal of a national family policy is to lower the stress levels of parents.

(D) Any national family policy that is adopted would include legislation requiring employers to provide paid parental leave and establishing government-sponsored day care.（A）

(E) Most children who have been cared for in daycare centers are happy and well adjusted.

我觉得 这两道题都有相似之处

好像都是因果型了

特别是第二题

a--->b; 然后利用/a--->/b 来做的

不知道我说的对不对

希望大家来帮忙

A推出B（political consideration因而revenue cannot cover cost）。现在条件换成非B（revenue can cover cost），所以推出非A（没有政治顾虑）。

算是逆否命题吧

2-5
profits would be vigorously pursued, 说明PRIVITE FIRM会追求足够的赢利来COVER THE COSTS。这是政府由于政治压力所办不到的. 所以private firm 必须不受政治压力影响。

2-17
建议通过给多假期来给员工减压，最终使FAMILY TO BE HAPPIER。
如果能证明FAMILY 不HAPPY 是因为工作压力造成，就可加强论点。

2－5和2－17还是有不同的

2－5是推导题，要完全建立在原文的基础上。所以用逆否命题＝原命题，这个肯定成立，最保险啦

但是2－17是加强。lawyer曾经总结过因果关系的逻辑思路。因-->果，现在异因 -->异果，就加强啦。在这种推理思路下削弱分别可以 异因同果（这个异因就是我们常说的他因削弱啦），或者是同因异果（说明必有它因，不过这里他因没有给出而已）。

呵呵，这歌被奉为GMAT专用歌了，笑

加油加油～！！
