有道逻辑题想跟大家讨论下

The critics of the one party claim that the President’s recent highway project cancellation demonstrates a vindictive desire to punish legislative districts controlled by opposition parties. They offer as evidence that the fact that 90 percent of the projects cancelled were in such districts. All of the cancelled projects, however, had been identified as wasteful in a report written by respected non-partisan auditor and the scheduled highway projects identified as wasteful in the report were not mostly projects in districts controlled by the President’s party. So the President’s choice was clearly motivated by sound budgetary policy, not partisan politics.

In the argument given, the two portions in boldface play  which of the following roles?

• A）The first is a claim that the whole argument wants to defend; the second is a circumstance on which that claim is, in part, based.
• B）The first is a claim that the argument calls into question; the second is an assumption that supports the position taken by the argument.
• …
• …
• …
  

答案选B。为什么？（第二段不是在陈述一个fact吗？不是assumption我觉得。）

关于整段我的理解是：有评论家认为总统取消的高速项目是出于向对手党派的打压。证据是90%取消的项目都在对手党的管辖区。然而，所有这些取消的项目都在一本无党派人士写的书里被评定为wasteful，同时那些已规划但也被评定为wasterful的高速项目大多不在总统党派的管辖区内。所以总统这个决策是出于合理化费用的考量而不是政党偏见。

选项B的内容都没问题，除了“assumption”这个词实在想不通。

assumption 没有必要过度纠结，因为引用一位作者的话，这些论述也只是这位作者的观点而已；再者，A 前半段 defend 就显然错了。

这题还有一个题目，就是把后半部分去掉问assumption 是什么，所以可能GMAT不是很纠结这个位置吧。
