请教LSAT-10-II-13,17,22

13. Criticism that the press panders to public sentiment neglects to consider that the press is a profit-making institution. Like other private enterprises, it has to make money to survive. If press were not profit-making, who would support it? The only alternative is subsidy and, with it, outside control. It is easy to get subsidies for propaganda, but no one will subsidize honest journalism.

It can be properly inferred from the passage that if the pres is

(A) not subsidize, it is in no danger of outside control

(B) not subsidized, it will not produce propaganda

(C) not to be subsidized, it cannot be a profit-making institution

(D) to produce honest journalism, it must be profit-making institution

(E) to make a profit, it must produce honest journalism

答案

17. Certain instruments used in veterinary surgery can be made either of stainless steel of nylon. In a study of such instruments, 10 complete sterilizations of a set of nylon instruments required 3.4 times the amount of energy used to manufacture that set of instruments, whereas 50 complete sterilizations of a set of stainless steel instruments required 2.1 time the amount of energy required to manufacture that set of instruments.

If the statements above are true, each of the following could be true EXCEPT:

(A) The 50 complete sterilizations of nylon instruments used more energy than did the 50 complete sterilizations of the stainless steel instruments.

(B) More energy was required for each complete sterilization of the nylon instruments than was required to manufacture the nylon instruments.

(C) More nylon instruments than stainless steel instruments were sterilized in the study.

(D) More energy was used to produce the stainless steel instruments than was used to produce the nylon instruments.

(E) The total cost of 50 complete sterilizations of the stainless steel instruments was greater than the cost of manufacturing the stainless steel instruments.

答案:B

这两题, 我真是一点头绪也没有.请教思路.谢谢.

22. Politician: From the time our party took office almost four years ago the number of people unemployed city-wide increased by less than 20 percent. The opposition party controlled city government during the four preceding years, and the number of unemployed city residents rose by over 20 percent. Thus, due to our leadership, fewer people now find themselves among the ranks of the unemployed, whatever the opposition may claim.

The reasoning in the politician’s argument is most vulnerable to the criticism that

(A) the claims made by the opposition are simply dismissed without being specified

(B) no evidence has been offered to show that any decline in unemployment over the past four years was uniform throughout all areas of the city

(C) the issue of how much unemployment in the city is affected by seasonal fluctuations is ignored

(D) the evidence cited in support of the conclusion actually provides more support for the denial of the conclusion

(E) the possibility has not been addressed that any increase in the number of people employed is due to programs supported by the opposition party.
答案:D,我选E,我觉得我是对的。

谢谢。

13 报社要生存...这是前提...生存有两个办法: 1. make profit 2 if not making profit, you should get subsidize, SUBSIDIZE的必要条件就是LYING...
所以要生存,要么: 1. MAKE PROFIT 2. 要么 NOT BE HONEST
D正是这个意思

2. 算术题目:
NYLON: 10个消毒过程  时间: 3.4* A
STAINLESS 50 个消毒过程 时间: 2.1 * A
当然是NYLON的单位消毒过程时间长...
B

3. 又一道算数题目:
结论是: 后任总统的失业人数比前任总统的人数少...
可是证据却是: 他在任期间失业人数增长了低于20%...这不是在打自己嘴巴吗? 只有负增长才可能导致事业人数比前任少啊...
所以是D

ALBERT,

3.4* A, A:the amount of energy used to manufacture that set of  nylon  instruments

2.1 * B: B:the amount of energy required to manufacture that set of stainless instruments

但是,A并不一定等于B啊,所以结论如何得的?

一个>20%,另一个<20%, 不是可以说明成效吗?

为什么需要负增长才能导致失业人数少?

谢谢。

sorry...
17看错题目
B比较的是: NYLON消毒和制造时间。
10 * 消毒时间 = 2.1 * 制造时间
所以消毒时间< 制造时间。。 所以B的表达和原文是不符合的。。。 而题目是要求选NOT TRUE的, 所以B

22。 他在任期间失业人数增长了低于20%... 这个数字是和前期的绝对数值比较。。。既然有增长。。当然肯定失业人数比前期的多。。否则还能叫增长吗?

22 关键在于如何理解“fewer people now find themselves among the ranks of the unemployed, whatever the opposition may claim”. 按常识(sorry),政客本应说比较失业率。而字面理解,似乎是说失业人数。如果按失业人数理解,albert的正确。可我总觉得政客总不至于如此蠢吧。

albert,谢谢你,说得对。

我以后对这种数学题要小心才成。一个是绝对数值 ,一个是相对数值 。做题要敏感。

谢谢。
