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.

Ans is C. I don't understand why average number of hrs is involved(I don't think it is accurate to say the more number of hours, the more tv produceds, since you need assumption that working efficiency is constant again...). I thought the answer should be something such as: the total number of tv exported to B country hasn't decreased.

Thanks much. Please help~~

组装时间没降低，换言之，组装效率没提高，产量没变大，

那么 droip in the number of television assemblers in Borodia不可能使产量维持原有水平，甚至更高，只可能减少。

又因为the number of televisions sold annually in Borodia has not change。

所以the number of televisions Borodia imports annually from Vernland has increased

B国自行生产量+从V国进口量=B国消费量，如果B国消费量不变，为了得出从V国进口增多且保持等式平衡，所以得出结论B国自行生产量减少；又B国自行生产量=B国工人数*B国组装效率，故只有B国效率不变，随着B国组装工人的减少，B国的自行生产量才减少
