Q2:

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.
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.

The correct one is C. why?

assumption可以看作一种加强（如果你同意这个观点的话），那么C是用了常见的排除他因的方式加强。题干中说每年的进口数量稳定，需求稳定，也就是说本国产量稳定。本国产量＝工人数×工作时间×单人效率（也就是C中说的每个工人作一台电视的单位时间）　也就是说在工人术下降的情况下，可以通过效率的提高来增加产量，而不需要增加进口。
