Q3:不明白是怎么做，请赐教！！

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.

答案是C，推荐用取非的方法来做

这题的答案是C可是我有个问题请教！用取非的方法那么C就变成如果B城的average hour spent on assembleing TV decline significiently那么我想知道这个选项是怎么削弱题目的结论B每年从V进口的计算机数量增加的阿？

因为题目中有一个小前提就是在B城组装的电视机的数量是下降的阿，并且每年B城售出的电视数量没有下降阿1
