Q36: TTGWD4-Q7:

Although the discount stores in Goreville’s central shopping district are expected to close within five years as a result of competition from a SpendLess discount department store that just opened, those locations will not stay vacant for long.  In the five years since the opening of Colson’s, a nondiscount department store, a new store has opened at the location of every store in the shopping district that closed because it could not compete with Colson’s.

Which of the following, if true, most seriously weakens the argument?

A.      Many customers of Colson’s are expected to do less shopping there than they did before the SpendLess store opened.

B.       Increasingly, the stores that have opened in the central shopping district since Colson’s opened have been discount stores.

C.      At present, the central shopping district has as many stores operating in it as it ever had.

D.      Over the course of the next five years, it is expected that Goreville’s population will grow at a faster rate than it has for the past several decades.

E.       Many stores in the central shopping district sell types of merchandise that are not available at either SpendLess or Colson’s.

答案是B

 GWD17-Q9:
            （CD-9 Q10）

Press Secretary:  Our critics claim that the President’s recent highway project cancellations demonstrate a vindictive desire to punish legislative districts controlled by opposition parties.  They offer as evidence the fact that 90 percent of the projects canceled were in such districts.  But all of the canceled projects had been identified as wasteful in a report written by respected nonpartisan auditors.  So the President’s choice was clearly motivated by sound budgetary policy, not partisan politics.

Which of the following is an assumption on which the press secretary’s argument depends?

A.      Canceling highway projects was not the only way for the President to punish legislative districts controlled by opposition parties.

B.       The scheduled highway projects identified as wasteful in the report were not mostly projects in districts controlled by the President’s party.

C.      The number of projects canceled was a significant proportion of all the highway projects that were to be undertaken by the government in the near future.

D.      The highway projects canceled in districts controlled by the President’s party were not generally more expensive than the projects canceled in districts controlled by opposition parties.

E.       Reports by nonpartisan auditors are not generally regarded by the opposition parties as a source of objective assessments of government projects.

答案B

谢谢大家！

第一题：先理出推理链：

很多discount store因为那个spendless discount store的开业而倒闭了。 而因为colson's 这家nondiscount store的开业，许多新开的店又倒闭了。

这时，weaken的方向必然是说这些店的倒闭与colson的开业无关。那么只有B可以达到这个目的。也就是说，如果新开的店是discount store,那么它的倒闭就不一定是由colson引起的，可能是由spendless引起的。

第二题。有人argue说总统cancel是highway project是针对反对党，因为90％的项目都在反对党控制的区里面。而根据一个无党派人士的报告，这些被cancel的项目本身都是有问题的，所以总统是英明的。

要找assumption，就要排除其它可能性。其它可能性之一就是，执政党控制区里的项目都是好的。所以只有10％的项目被cancel。所以B就是答案了。

第一题解释的挺好的，第二题还是有点云里雾里呢

还请楼上详解～

(1)   90% of the president’s cancellations are in districts controlled by opposition parties.
(2)   all of the cancellations are wasteful.

Conclusion: president is motivated by budgetary policy, not by partisan problem.

Assumption: B取非 if most of the wasteful projects are in the president’s districts, then 90% in (1) is impossible.

Therefore, most of the wasteful projects are not in the president’s controlled district.
