The average hourly wage of television assemblers in Vernland has long been signifi cantly 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?

(A) The number of television assemblers in Vernland has increased by at least as much as the number of television assemblers in Borodia has decreased.
(B) Televisions assembled in Vernland have features that televisions assembled in Borodia do not have.
(C) The average number of hours it takes a Borodian television assembler to assemble a television has not decreased signifi cantly during the past three years.
(D) The number of televisions assembled annually in Vernland has increased signifi cantly during the past three years.
(E) 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，但我觉得一个都不对～～

C取反，B的电视机组装工装一台电视机的平均时间在过去三年大幅减少（也就是人均生产力提高），那就消弱了题目中的进口V的电视会增多的结论，B虽然组装工少，但效率提高了，照样没问题！！

谢谢你的回复。这道题目没有求消弱，而是寻找argument的支撑点。我发现我的问题所在了，是我自己审题不清。“the number of televisions sold annually in Borodia has not changed” 这句话我以为Borodia产的在Borodia卖的电视机数量未变。其实是在Borodia卖的电视机的总量（#of Borodia TV + # of Vernland TV）未变。总量未变 -> V国的电视机销量增加。 也就意味着B国的电视机销量减少。这样的话按照C的选项，假如生产效率未变，生产力减少，那么B国的生产量就减少，销量也减少，那么就支撑住了论点。
