GWD-5-Q3:

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?

The number of television assemblers in Vernland has increased by at least as much as the number of television assemblers in Borodia has decreased.
Televisions assembled in Vernland have features that televisions assembled in Borodia do not have.
The average number of hours it takes a Borodian television assembler to assemble a television has not decreased significantly during the past three years.
The number of televisions assembled annually in Vernland has increased significantly during the past three years.

Vernland电视机的销售数量没有变化，但是Vernland的装机工人总数却下降了；如果人均的工作效率提高了，也就是说单个小时内装机数量增加了，那么即使工人减少，生产的总量也不会有太大的变化的。

所以C是最佳答案。
