请教2道新GWD-4中的逻辑题

GWD6-Q14:

Political Advertisement:

Mayor Delmont’s critics complain about the jobs that were lost in the city under Delmont’s leadership.  Yet the fact is that not only were more jobs created than were eliminated, but the average pay for these new jobs has been higher than the average pay for jobs citywide every year since Delmont took office.  So there can be no question that throughout Delmont’s tenure the average paycheck in this city has been getting steadily bigger.

Which of the following, if true, most strengthens the argument in the advertisement?

A.      The average pay for jobs created in the city during the past three years was higher than the average pay for jobs created in the city earlier in Mayor Delmont’s tenure.

B.       Average pay in the city was at a ten-year low when Mayor Delmont took office.

C.      Some of the jobs created in the city during Mayor Delmont’s tenure have in the meantime been eliminated again.

D.      The average pay for jobs eliminated in the city during Mayor Delmont’s tenure has been roughly equal every year to the average pay for jobs citywide.

E.       The average pay for jobs in the city is currently higher than it is for jobs in the suburbs surrounding the city.

答案是D, 我选A。什么思路呀?

GWD6-Q38:

Three large companies and seven small companies currently manufacture a product with potential military applications.  If the government regulates the industry, it will institute a single set of manufacturing specifications to which all ten companies will have to adhere.  In this case, therefore, since none of the seven small companies can afford to convert their production lines to a new set of manufacturing specifications, only the three large companies will be able to remain in business.

Which of the following is an assumption on which the author’s argument relies?

 

A.      None of the three large companies will go out of business if the government does not regulate the manufacture of the product.

B.       It would cost more to convert the production lines of the small companies to a new set of manufacturing specifications than it would to convert the production lines of the large companies.

C.      Industry lobbyists will be unable to dissuade the government from regulating the industry.

D.      Assembly of the product produced according to government manufacturing specifications would be more complex than current assembly procedures.

E.       None of the seven small companies currently manufactures the product to a set of specifications that would match those the government would institute if the industry were to be regulated.

答案是E, 我选A
            
是不是因为逻辑讨论的中心在small companies, 而非large companies?

先谢过!

第一题:E的郊区和本文无关,应该排除。A的比较范围错。我这答案版本是D,供参考。

第二题:我也感觉A对,A是原命题的逆否命题嘛。

请高人指点

我这答案版本是D,供参考。

答案确实是D,已改。

 

A的比较范围错

是不是答案中的during the past three years给定义坏了?!一定是,因为原文没说。

谢谢

命题的逆否应该是 NOT only the 3 large companies left (也有小公司留下来 ) 逆否不应该是“没有大公司倒掉”。
题目的因果关系是:小公司没有钱改动 =〉只有大公司留下来,所以你否也不应该和regulate与否有关系。原命题本事就是在regulate的环境下的推论。

刚又自己看了下第二题的E选项,发现之前被NONE给搞昏头了,其实是很简单的架桥:

正是由于你小公司达不到我政府出台新规定的标准,所以你才需要改造,而你又没钱改造,才三个大公司乘机而入了。其实10个公司是机会平等的。所以E正是填补了原文提出政府治理,和7个公司花钱改造的GAP。

看这样说你懂不。

至于A在架桥情况下就是无关了选项
