GWD17-9查过以前的讨论

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?

1. Canceling highway projects was not the only way for the President to punish legislative districts controlled by opposition parties.
2. The scheduled highway projects identified as wasteful in the report were not mostly projects in districts controlled by the President’s party.
3. 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.
4. 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.
5. Reports by nonpartisan auditors are not generally regarded by the opposition parties as a source of objective assessments of government projects.

答案是B，我选E。

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

题目要找Secretary的Assumption。我的理解是E。B和Secretary的论证无关啊。

还有，把B取非，这些工程是总统派系的，加上Auditor的证明，不是加强了结论吗？

看了网上的讨论，还是不明白我的理解哪里有问题。

这个题我是这么分析的：

首先这段话里哪个地方是有“开环”(非封闭系统吧)的，或者哪句话在逻辑上有文章可做

应该是这句：But all of the canceled projects had been identified as wasteful in a report written by respected nonpartisan auditors

而这里面重要的是written by respected nonpartisan auditors说明了什么问题。

这就是一个隐含条件了：这玩意儿应该是个公正的立场

那看一下后面的答案

B说明了reports没有特别倾向于一方，E说明了reports的功用

所以B有点道理。。。

Allen's point:

这道题E 是无关的，原文里面说RESPECTED 就说明了不可怀疑资料来源充分性

我说说B ，不知道大家以前做没做过一个逻辑题

说一个杂志社，被别人批评对 保守观点的文章保护的时候，举了个例子，说上个月他们在发现观点的时候马上取消发行，然后补充了一个观点激进的文章 一起发行。

问EVALUATE

答案就是：是否在发现激进观点的时候也会补充一个保守观点。

其实这两道题是一样的，都是考虑一个通过比例来确定倾向性的问题。

B 取非

The scheduled highway projects identified as wasteful in the report were（ not） mostly projects in districts controlled by the President’s party.   都在总统管的那片，那还偏向什么？

就如你说的把B取非，得出没有偏向，不是support那个秘书的结论了吗？而假设需要的是取非削弱啊。

再说了，B是在critics的逻辑里面绕圈子，我觉得对秘书的逻辑起不到作用。

嗯，我也觉得allen的说法会不会太简单了一些。。。

说实话，这题我是想了很久，一开始我也选的E。后来在脑袋里画了个图，定了定各类元素之间的关系，最好很不情愿的认为B更好一些。

看了半天题，我终于搞明白了。

首先说说E,这个是很明显的无关选项。因为它违反了gmat CR中正确选项要表达客观事实或观点的原则。反对党的观点又能说明结果什么呢？而且人家是反对党当然要反对总统了。即使除去客观这个原则不说，我们还是能发现这个选项也不对。因为它实际上在起weaken的作用。而assumption题实际上是一种特殊的support题。

再说b.其实我想大家和我一开始一样也犯了一个错误，那就是没有注意两个词:题目中的canceled projects indentified as wasteful in the report和选项中的scheduled projects indentified as wasteful in the report.这是两个不同的概念。两个元素共同组成了报告中认为是浪费的项目。(注意后面这个元素文章中没有提到）

搞清楚了这两个概念，下面我们就用取非法做吧。b的意思是那些计划中的项目并且又被报告认定为浪费的项目大部分都在总统党的控制区内。也就是说在被认定为浪费的项目中有在总统党区的，有在反对党区的。但是被cancel的却都是在反对党区的。所以可见，总统在利用这个控制反对党区。文章被weaken.

所以b对。

open to discuss

其实这个就是个阅读的问题，估计人家美国人对英语敏感一看就明白了。唉，我们还要盯着scheduled看半天，才明白。

逻辑说到底还是在考阅读啊

谢谢。这个用集合的交集概念理解起来是那么回事。不是MM提醒，我还没有注意到是两个不同的集合。

谢谢各位的耐心解释。

D should be the answer
