Q14:

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.

Answer: C

不是很明白题目的意思，可以指教一下吗？

从题目中可以看出v生产电视的成本（工资）低于B，而在过去三年中B的电视机销量没有变。这部分电视机销量包括B自己生产的和从V进口的。所以B的装配工人减少一位着B自己生产的减少，而题目又说B的总销量未变，也就是说从V进口增加。C选项取非，就是说B生产效率提高（每台生产时间减少），那既是工人减少也不能说明他们销量减少。所以削弱。加not正好符合题目

明白了，谢谢，我想问你做逻辑assumption题时，会不会每个选项都取非，如果真这样的话，时间又会多花了.
