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.

答案是b，但是文中没有说到President's party啊

GWD17-Q23:

Because visual inspection cannot reliably distinguish certain skin discolorations from skin cancers, dermatologists at clinics have needed to perform tests of skin tissue taken from patients.  At Westville Hospital, dermatological diagnostic costs were reduced by the purchase of a new imaging machine that diagnoses skin cancer in such cases as reliably as the tissue tests do.  Consequently, even though the machine is expensive, a dermatological clinic in Westville is considering buying one to reduce diagnostic costs.

Which of the following would it be most useful for the clinic to establish in order to make its decision?

A.      Whether the visits of patients who require diagnosis of skin discolorations tend to be shorter in duration at the clinic than at the hospital

B.       Whether the principles on which the machine operates have been known to science for a long time

C.      Whether the machine at the clinic would get significantly less heavy use than the machine at the hospital does

D.      Whether in certain cases of skin discoloration, visual inspection is sufficient to make a diagnosis of skin cancer

E.       Whether hospitals in other parts of the country have purchased such imaging machines

这题答案是c，为什么跟heavy use 有关系呢？

请教各位牛牛了~~~~

这儿有一个总统党 和一个非总统党

题目说因为所有被叫停的项目都被那个report指出是无用的 所以这些项目应该被停 政府不是在偏袒总统党

这里面的推论是report里指出的无用项目并非大部分都是总统党辖区里的

因为如果无用项目大部分都是总统党辖区里的，那么总统党辖区里的项目被停的应该更多，既然90%被叫停的项目都在非总统党辖区里 当然政府是有偏袒了

只有heavy use了省下来的钱才够抵消昂贵的仪器钱，要没人来看病那机子不白买了
