OG15 CR113 看答案都看不懂TAT

这真是做GMAT以来碰到的第一次连答案都看不懂的情况……求大神用白话详解TAT

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.

答案是这么说的：
What assumption does the argument depend on? The fact that fewer individuals in Borodia are
working as TV assemblers is offered as evidence that TV imports from Vernland into Borodia have
likely increased. That piece of evidence is relevant only as an indication that the number of TVs
being produced within Borodia has decreased. But a drop in the number of TV assemblers does not
indicate a drop in the number of TVs being assembled if the number of TVs an average assembler
puts together has increased. Thus, the argument must be assuming that the average time it takes an
assembler to put together a TV has not significantly decreased.

完全不能理解V城工人工资和B城电视销量有什么关系？B城税收不变又和销量有什么关系？ 求解TAT

楼主好，麻烦以后发完帖子可以检查一下layout哈，这样看的比较清楚。

关于这道题目：

题干中给出的facts有：
1. wage@Verland < wage@Borodia
2. 3年前Borodia对Verland电视的关税降低了，而且这三年来Borodia每年的电视销售量不变（包括自产和进口）。
3. 最近，Borodia生产电视的工人数量变少。

因此，得出的conclusion是：
Borodia从Vernland进口的电视的数量很有可能增多。

从facts我们可以知道的是Borodia每年自产和进口的电视加起来销量是不变的，如果要推出结论“Borodia从Vernland进口的电视的数量很有可能增多”，我们需要“Boridia自产的电视量应该是变小的”。所以题目中的逻辑漏洞或者说missing掉的部分是：

作者默认：Borodia生产电视的工人数量变少====》Boridia自产的电视量变小

所以逻辑上的漏洞是：如果Borodia工人的生产效率有了很大的提高，那么就算工人数量变少，Boridia自产的电视数量还是可以保持不变甚至增加。

所以这个漏洞取非以后即可得到assumption，即Borodia工人的效率没有很大的提高，选择C。

阅读中注意 the number of telly 和the number of telly assembler
然后解题的时候注意 number of assembler * work hours= production
最后因为assumption题目，使用negation method做检查。

关于这道题目：

原来是这样！我看到assembler的时候，下意识以为是“电视运送工人”，所以没有想到生产方面。而对第二个fact的理解又有误……总之就是掌握复杂逻辑的能力还很弱啦。谢谢解答~

解释的相当相当清楚呢，手动赞一个那么，“Theaverage hourly wage of television assemblers in Vernland has long beensignificantly lower than that in neighboring Borodia”这段话是没用吗？

这句话可以认为是背景条件，让人更想当然的觉得Vernland的电视会更便宜，但是事实上并没有什么作用。
