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

   没想明白怎么得到C的，谁能指点一下？还有，A哪里不对。谢了！

even the number of television assemblers drops, if the productivity increases, B will not need to import more tv from V

C is the one that makes this point

Thanks, mbamom. 经你解释，我明白些了。而且，我觉得还有隐含的假设是：1）B国对TV的需求一直是不变的；2）当B国国内生产不足以满足本国需求的时候，可以通过进口满足需求。

“the number of televisions sold annually in Borodia has not changed” 表示这三年里B国对TV的需求通过稳定的国内生产+稳定的进口得到了满足。

这样才能得到：当assembler人数减少 & 单位产品工作小时数不变(productivity不变) --> 国内供应减少 -->进口增加

再看看选项，B,E都可以先排除，A,D不是结论成立的必要条件（V国的生产数量不用考虑，因为题目没有说V国的生产、需求状况）

以上是我自己总结的分析。帮分析一下对不对。多谢！

刚做完这套题,我是这么考虑的:

在看选项之前,认为"题目中存在不可靠的因果关系: 总产量不变且工人少了=>要从他国进口产品",

就不能多生产点吗?除非该国的工人的出产量已经达到上限.

抱着这种想法,扫一遍选项,觉得都不大好,唯独C沾边.

再分析一下,确实,如果每个产品的装配时间少了,那么总出产量就大了(默认工人的总工作时间不缩短,不大好). 这跟我的事前分析一致,所以就选它了.

楼主能否说说这套题中的2个BF题(19和22)怎么做吗?我一点都没思路,抓狂中......

汗一个

愣是把The average number of hours 看成了The average hourly wages

C is the answer.

考试的时候这样的题比较难，信息量比较大，最好写一下逻辑链一下就看出来了。B过的电视销量不变，B从V进口多了，那么本国生产就少了。本国少了，本国员工下降了，十有八九是效率没提升
