?，112. 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[c1].

Which of the following is an assumption on which the argument depends?

(A) The number of television assemblers in Vernland [c2]has increased by at least as much as the number of television assemblers in Borodia has decreased.

(B) Televisions assembled in Vernland have features [c3]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 significantly during the past three years.[c4]C

(D)[c5] The number of televisions assembled annually in Vernland has increased significantly 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[c6] decrease in the next few years.

[c1]因果型结论

[c2]与因果均无关

[c3]无关

[c4]排除他因

[c5]同A

[c6]文中讨论的是已经发生的事情
没搞明白为什么选C，没看出来和前提有什么关系？请高手指点。

Premise: Televisions are made in both V and B, and B imports TV from V. The number of televisions sold in B keeps constant. These TV's come from both B and V. the number of TV assemblers in B decreases.

Conclusion: TV imports from V to B has increased.

The assumption is that if TV assemblers in B are fewer, there will be fewer TV made in B. A further assumption is that the efficiency of TV assemblers in B has not changed (answer C).

If you use negation method, you would find that after negating C, the argument falls apart. If assemblers in B become more efficient, they can produce the same amount or more TV than before, even with a lower number of total assemblers.

十分感谢sdcar2010,每次都能得到你的慷慨帮忙!further assumption is the key for me.Thanks a lot.

再问下，如果像c说的，没有显著的减少，那么我可以理解为增加吗？觉得没有显著减少，肯能减少，可能增加，可能不变，这个是变量，不能确定最终b得电视机是增加还是减少？

Not decreased significantly = might be slightly decreased, no change, or increased.
The question is not asking for a sufficient assumption, but a necessary one.

Therefore, with the necessary assumption, it is not sufficient to lead to the conclusion of increasing output in TV.

But an increase in productions DEMANDS the necessary assumption of (C).

谢谢

这个题我不明白的一点是，average hour wage和生产率有必然联系吗？如果没有为什么要把这个东东放上去，如果有，为什么有呢？

wage relates to cost, then to the sale price of the product.

首先谢谢您，一直热心解决广大处于水深火热之中的朋友们的疑难问题。

但是，您说，工资低，成本低，和价格有关，那么这道题目和价格没有关系啊。
最终就是assembler 的数量*工作效率=产出，和价格有什么关系。

我觉得第一句话放在这里特别有迷惑性，在我没有完全读懂题目意思的时候，就选了Ｅ，因为Ｅ和工资相关。
