GWD 7-3

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 droip 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.
答案是C,我想不通这点,在B平均组装电视的时间没有减少和它从V进口电视数量的增长有什么关系..

原文说对产品需求数没变，b国的员工减少，所以推出进口将会增多：

1。如果b国生产效率提高了，减少了员工后还是可以生产出同样多产品，就不对多进口

反之，员工数减少了，效率没变，或没有显著提高，所以生产的产品就少了，需要依赖更多进口来满足国内需要

c其实是说在过去3年里，b国的生产效率没有显著提高，符合要求
