拜托NN解答一道OG13 113，老题新问，文中意思把握不准确

Hugateddybear

113.  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?
(A) The number of television assemblers in Vernland has increased by at least as much as the number of television assemblers in Borodia has decreased.
(B) Televisions assembled in Vernland have features 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.
(D) 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 decrease in the next few years.

这道题目之前曾经有NN解答过，他的解释如下：
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).
我的问题在于不能通过stimulus的信息概括出他所说的premise，在原题中我标记红色以及他解释中标记红色的地方，我没能明白是什么意思。请NN们指教一下这其中的道理。感激不尽 ：）

哦。我认为这道题的前面部分是背景：即暗示了在B国TV的消费需求数量不变的。

然后逻辑链是， 前提：B国的 ...

他们的生产率没有提高，为什么c是用has not decrease呢，我就是看见这个，就觉得错了的

我说下自己的看法哈。不对勿拍。
貌似题中是没有明确说明TV是产自B和V的。
但是如果纠结于这个，假设这个premise不成立的话，这道题就没法做了。肯定这里谈论的TV，题目默认是在B、V两个国家形成的一个封闭圈内讨论，由于BV两国之间是存在进出口的，所以B国的TV来自于B和V。
题干的大概意思就是，V国的assembler 比B国的工资要低。B国的关税下降，国内的TV销售量并没有发生变化，（按理说此时V国的TV更有竞争力），而此时又得知B国的assem又变少了，那如果他们的效率还和以前一样的话，他们的生产量和销售量绝对会减少，而总TV销售量没有变化的话，只能说明从V国进口了。

嗯嗯，谢谢晴晴 你说的我懂啦 但是呢 还有个小问题： Since Borodia dropped all tariffs on Vernlandian televisions three years ago, the number of televisions sold annually in Borodia has not changed. 这句话其中的因果关系在哪儿呢？为啥B对V的关税下降，就使得B销售量不变呢？

这个since在这里表示的是尽管的让步的意思，也就是说句子意思是“尽管关税下调，但是TV销售总量还是不变。”这就是说按照常理，大家都觉得关税下调进口增加，如果之前国内自己的生产量不变的话，总销售量应该增加才对。 从答案倒过来分析，就是因为国内的总销售量下降了，所以才可以造成总销量不变。

since居然还有表示让步的含义？我还以为是因果关系呢啊！

CR题研究语法来了。since在这里的意思是自从，整句话的意思是自从b国三年钱调低了对v国电视机的关税，b国的电视机销量就没变过。不是因果关系，这句话主要就是说b国电视机销量三年来没变，包括今年。

我认为这块意思是指强调 。B国的对tv消费的消费需求没变吧 ，求解答 ？？我的理解 。那么B国对V国进口需求上升，则 B国国内生产的TV下降，那么集装 人员 变少 ，则他们的效率并没有提升 ，因此选C
