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?

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.

原文说装配工数量减少了（言下之意B国生产的电视机少了） 推出结论B 国的进口变多了

C取非是每个装配工花的时间少了 也就是说每个装配工在相同时间生产的电视机增多了 也就不需要进口了
