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.

这道题，答案是C，我选的是A。

这题怎么解呢？我怎么想也不明白。

谁能帮忙分析一下。

 assumption就是寻找gap

题目中的gap：assemblers的减少等于产量的减少

填补这个gap：产能不变~

我是这么理解的: 价格由cost 决定, labor efficiency 是cost 的组成成分之一.如果过去

三年B的工作时间下降,它的cost及价格都比V的低, 那么import from V就不可能了

原文evidence 1:B国的销售数量维持不变;2.B国工人减少了。所以结伦是:B国的进口数量要上升。所以搭桥就是 B国工人的生产能力没有上升。

C答案就是 每个工人制造电视所花费的时间没有降低。 （就是说生产力没有上升）。A不如C，我想法是：因为讨论的关键是B国，A国的因素不足以说明问题。另外at least太绝对了

我也选A...A的答案可以直接推得原文结论。

而C中我觉得反而有削弱的意味呢，实在困惑答案怎么会是C的。

C我用defender方法先取非，就变成“B国的assembler人数急剧下降”。既然B国造电视的人急剧下降，而B国的电视销量没变，反而加强了是因为 V国电视进口增加的答案。

请牛牛解困~~~很不理解这道题~~~~
