Goronian lawmaker: Goronia's Cheese Importation Board, the agency responsible for inspecting all wholesale shipments of cheese entering Goronia from abroad and rejecting shipments that fail to meet specified standards, rejects about one percent of the cheese that it inspects. Since the health consequences and associated costs of not rejecting that one percent would be negligible, whereas the cost of maintaining the agency is not, the agency's cost clearly outweighs the benefits it provides.

Knowing the answer to which of the following would be most useful in evaluating the lawmaker's argument?

正确答案: C

Goronian lawmaker:  Goronia's Cheese Importation Board, the agency responsible for inspecting all wholesale shipments of cheese entering Goronia from abroad and rejecting shipments that fail to meet specified standards, rejects about one percent of the cheese that it inspects.  Since the health consequences and associated costs of not rejecting that one percent would be negligible, whereas the cost of maintaining the agency is not, the agency's cost clearly outweighs the benefits it provides.
Knowing the answer to which of the following would be most useful in evaluating the lawmaker's argument?
A. Are any of the types of cheeses that are imported into Goronia also produced in Goronia?
B. Has the Cheese Importation Board, over the last several years, reduced its operating costs by eliminating inefficiencies within the agency itself?
C. Does the possibility of having merchandise rejected by the Cheese Importation Board deter many cheese exporters from shipping substandard cheese to Goronia?
D. Are there any exporters of cheese to Goronia whose merchandise is never rejected by the Cheese Importation Board?
E. How is the cheese rejected by the Cheese Importation Board disposed of?

OA: C

In the nation of Partoria, large trucks currently have a much higher rate of traffic accidents per mile driven than other vehicles do.  However, the very largest trucks—those with three trailers—had less than a third of the accident rate of single- and double-trailer trucks.  Clearly, therefore, one way for Partoria to reduce the number of traffic accidents would be to require shippers to increase their use of triple-trailer trucks.
Which of the following, if true, most seriously weakens the argument?
A. Partorian trucking companies currently use triple-trailer trucks only for long trips using major highways, which is the safest kind of trip for large trucks.
B. No matter what changes Partoria makes in the regulation of trucking, it will have to keep some smaller roads off-limits to all large trucks.
C. Increased use of triple-trailer trucks would mean that large trucks would account for a smaller proportion of all miles driven on Partoria’s roads than they currently do.
D. In Partoria, the safety record of the trucking industry as a whole has improved slightly over the past ten years.
E. The volume of truck traffic on Partoria’s highways could be reduced by encouraging shippers to use rail transport whenever possible.
OA: A

看了答案还是没有想明白,请教大家,谢谢

讨论一下:
89.Since the health consequences and associated costs of not rejecting
that one percent would be negligible, whereas the cost of maintaining
the agency is not,
the agency's cost clearly outweighs the benefits it
provides.
划线部分是premise:说的是什么捏---- 忽略那1%的劣质cheese带来的食品安全问题及成本很低,可以被neglected。但是这个Board的运营成本很高。 
所以conclusion是:维护这个Board的成本,高于它的带来的好处

-----从premise到conclusion的逻辑线没有问题。

那么要EVALUATE,结论是不是正确,只要看 实际情况是不是符合premise就可以了。

A,D,E is irrelated choice。。。。

B,C中选:

B试图评价Board的运营成本,但是out of scope了。评价 一个组织运营成本的高低,不决定于他是不是努力降低成本,以何种方式降低。而是决定于降低后的 实际成本。无论B是否成立,都不影响对board运营成本高的评价。(取是取非都无关)

如果B这样说:在降低成本以后,是否board的operating cost已经非常非常低?那么B有可能成为选项。

C很清楚了:是不是 Board检查出1%劣质产品,阻止了远远不止1%的 可能的substandard cheese进入market。如果C是的话,那么忽略那1%的劣质cheese带来的食品安全问题及成本就很高了,premise就不成立。conclusion就不成立。 如果C不是的话,premise就成立,conclusion就成立。

OA: A

这个题,有何不解?

A是典型的他因削弱:
原题逻辑是 THREE TRAILER的truck带来安全,所以用three trailer的货车取代一般货车带来安全。

A说 three trailer安全的原因是在safe highway上。那么three trailer本身带来安全吗?就未必了。
削弱premise,削弱conclusion

哎,可能是早上做了一套模考又做逻辑,脑子有点转不动了,把89题里面的substandard看成了substantial....理解了半天
90题现在也不知道刚才为什么没有理解,差根玄了。 这个状态怎么考试阿。。。。
看了你的分析,完全清楚明白,无比感谢!

我怎么觉得如果C答yes的话应该是才是说成本变高,而答NO才是顺应题目成本不高呢。
哦,是的,我连中文都看错了。。。。。
