标题: GWD 7-3 难题再现

能讲讲解题思路吗，为什么我老是把对的最先排除掉了

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 droip 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?

The number of television assemblers in Vernland has increased by at least as much as the number of television assemblers in Borodia has decreased. 工人人数的比较。
Televisions assembled in Vernland have features that televisions assembled in Borodia do not have.
The average number of hours it takes a Borodian television assembler to assemble a television has not decreased significantly during the past three years.
The number of televisions assembled annually in Vernland has increased significantly during the past three years.
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.[C]

C is the assumption. C states that the time of a B assembler to assemble a TV hasn't drop, we know, sum= N(assemebler) * working hour / T ( time needed to assemble a TV). To be symplified, sum=N*H/ T, if T drop, even N drop, then sum will probably not drop. C declares that T hasn't drop.

logic exhibits a causal relationship.

# of TV sold in B unchanged + removal of tariff -> # of TV imported from V increased and # of TV made in B dropped. # of TV made in B dropped-> # of assembler dropped in B.

C excludes another reason that may cause drop in # of assembler in B such as increased productivity.

C?

the answer is C

C excludes another reason that may cause drop in # of assembler in B such as increased productivity.

我非常赞同一位NN说的，assumption的解法，答案一种是弥补了evidence& conclusion之间的缺陷，一种是not+weaken,即如果选项取非则结论不成立。我自己的经验是：老错的原因是在我真正成为NN之前，不要先自己预想一个答案，然后沿着这个思路去答案里找，这样很容易掉到ETC挖的陷阱里去。请真正的NN指正！

引用：“另外，我没有按提醒分类，即weaken，support，assumption等等，而是按逻辑套路分类，因为这个才是根本，一道题逻辑套路弄清楚了，不论是出什么题，都能找到答案。所谓逻辑套路，无非就是因果关系，比较关系，数量关系，差异关系

因果关系的关键词一定在原因，答案必须跟原因有关；

比较关系的答案要涉及比较双方；

数量关系主要是百分比；一般段落里有百分比/rate，选项优先看total number；

差异关系主要是指，前提讨论的内容和结论存在概念/范围上的差异，答案就要针对这个差异；”

作了一定数量题，上了各种的培训班，一直没什么起色，试试换一种思维模式~
