[讨论]GWD5-Q3不明白~

求助各位XDJM，GWD5-Q3不明白，我选了A啊...为什么答案是C？？？谢谢解答~

The average hourly wage of television assemblers in Vernland has long been significantly lower than that in neighboring Borodia.  Since Borodia dropped all tariffs on Vernlandian televisions three years ago, the number of televisions sold annually in Borodia has not changed.  However, recent statistics show a drop in the number of television assemblers in Borodia.  Therefore, updated trade statistics will probably indicate that the number of televisions Borodia imports annually from Vernland has increased.

Which of the following is an assumption on which the argument depends?

A.      The number of television assemblers in Vernland has increased by at least as much as the number of television assemblers 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.

这是题目帮你贴上

A取非，v的assemblers 增长比B的assemblers 下降的少。文章表面再说装配工的增减，而通过结论（要增加进口）来看实际上是在说产量的增减。产量与工人的多少没有直接联系，A无关

答案是c，一道数学公式 总产量=工人数*每个工人生产率。C取非就是说B的工人的生产率大大提高，那么即使B的工人减少了，他们依然有可能保持原来甚至更高的产量。

文中说B国的电视机销量基本保持不变，则如果从V国的进口量上升的话则，所需要的假设就是B国自己的产量没有显著的提高（在装配工人减少的前提下）， 即每个工人装配电视的效率没有提高。

所以是C

啊~谢谢哦~

好多题都是A+B=C或A*B=C的类型

Tariffs↓
        →the price of V tv in B↓ and V tv becomes more competitive in B→sales amount of V tv in B↑

Sales amount of tv in B(unchanged)= sales amount of V tv in B(imported)↑ + sales amount of B tv(self-produced)（so↓）

Sales amount of B tv(↓)=yields amount of B tv (↓)= productivity of each assembler（so unchanged or↓）* the number of assemblers in B(↓)
