GWD5-Q3:

The average hourlywage of television assemblers in Vernland has long been significantly lowerthan that in neighboring Borodia.  SinceBorodia dropped all tariffs on Vernlandian televisions three years ago, thenumber of televisions sold annually in Borodia has not changed.  However, recent statistics show a drop in thenumber of television assemblers in Borodia. Therefore, updated trade statistics will probably indicate that thenumber of televisions Borodia imports annually from Vernland has increased.
Which of thefollowing is an assumption on which the argument depends?
A.   The number of television assemblers inVernland has increased by at least as much as the number of televisionassemblers in Borodia has decreased.

B.    Televisions assembled in Vernland have features that televisions assembled in Borodia do not have.

C.   The average number of hours it takes a Borodian television assembler to assemble a television has not decreased significantly during the past three years.

D.   The number of televisions assembled annually in Vernland has increased significantly during the past three years.

E.    The difference between the hourly wage of television assemblers in Vernland and the hourly wage of television assemblers in Borodia is likely to decrease in the next few years.
请问答案为什么跟小时有关啊？可否引导一下思路

我选C，因为根据GWD的法则，主干没有否定词的选项全部去掉，现在就留一个C，所以正确

别问我为什么，我只会做题

结论是，B进口V的电视数量增多了。把c取非，B工人的工作时间显著减少。哪削弱结论了？没看出来为什么选c。。。

前提：B城的装配工越来越少了，与此同时，B城的电视销售没变。     推出结论： 从V进口的电视机变多了。

补充推理过程：虽然B城装配工少了，但B城工人的工作效率提升了。 那从V进口的电视未必会变多。 即为结论的前提

即为选项C所述。

B城降低从V城进口电视的关税，但是B城卖的电视总量不变；B城电视装配工减少了，因此B城从V城进口的电视多了——假设：B城电视装配工装电视的平均小时数没变（工作效率没变），因为如果工作效率提高了，即使是不进口，装原来数量的B城电视，所需要的装配工也会减少
