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.

为什么选B???

是不是只有当前提是wasteful in the report were not mostly projects in districts controlled by the President’s party的时候,后边的一系列情况和结论才得以产生,所以B是假设.

还是请诸位谁来指教一下吧,我理解的不透彻,谢谢

取非若大部份确定为浪费的由执政党掌控的区域..而总统却cancel那些由在野党控制的区域

则weaken Press Secretary结论:说President’s choice was clearly motivated by sound budgetary policy, not partisan politics.

所以ANS:B CORRECT!

请指教

一直不会用取非的方法,不太明白...汗,还请指教...

哦,有些明白了,难道做求假设是试题,都要取非看是否weaken结论么,如果weaken了,该选项就是假设...

Yeah..这只是小技巧帮助我们快速定位ans

其实若按一般正常思路下就是我们必须要有该选项才能使原文结论成立..
