GWD2 - 14

请各位N人指点迷经。这题我怎么看也看不出来答案C是正确答案。多谢！！！！

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?

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

   
           

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

   
           

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

   
           

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

   
           

5. 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.

        Answer: C

题目说的是:

Borodia的电视销量不变，但是产量却减少了。所以得出结论，Borodia从Vernland每年进口的电视机有所增加

为什么要进口呢？当然是因为进口的成本要不自已生产的成本低。因为取消了所有的关税，所以进口的成本就等于生产的成本。

C的意思是说，在Borodia生产的效率不会有太大的提高，这样的话，在Vernland生产电视机的成本才会比在Borodia生产的成本低很多（因为第一句就说，工钱差别很多），加上些利润，还会比Borodia生产的成本低，所以Borodia才会从Vernland进口。

先排除5：因为这是个预测，而不是Assumption

4也不能说明问题，因为Vernland增加生产量可能因为本国的需要，或出口给其他国家，和1一样，并不能说明进口会增加。

而2呢，应该不是一个主要原因吧，和题目中提到的有点远。

个人意见，希望没有误导你@_@ ^_^

多谢楼上这么美女,我明白了.
