为什么选C啊?我觉得B没有DECREASE在文中无法看见好像应该属于INFER题而非ASSUMPTION吧!

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 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.

好像。。。是这样的哦，，，就是B的每年的彩电销量一直没什么变化，但是现在B的彩电组装商少了，题目要推出的结论是，B从V进口的彩电多了。。。。然后为了使这个结论成立，B生产彩电的效率当然不能变——因为如果B国家的厂商虽然少了，但是效率大大提高，在B生产的彩电数量还是没有少，也就没有必要从V进口更多的彩电了。。。。

不好意思我表达能力有点差。。。反正我的意思是，如果要得出一个结论，比较的量里面应该只有一个是变量，如果前提里面n多量都在变，结论也就不那么有力了。。。
