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.

为什么选C呢？还是不明白啊！哪位给我讲讲吧。

Average number of hours decreasing means the output increasing. If the

output increases and the market remains stable, the drop in the number of

television assemblers will not cause an increase in the number of televisions

Borodia imports.

 哦，是我没看清楚题目呢。

是ASSEMBLER数减少呢。

谢谢

 C is best,

Borodia compete with Vernland with the factor of efficience( average hours of assembly) and tariff, with tarrif drop, in contrast, efficiency should increase, or Borodia will lose its core competitive advantadge in term of arguement above.

For you reference.
