涛涛2-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 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.
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.
为什么选C?

所以了，进口的television多了，总的卖出的不变the number of televisions sold annually in Borodia has not changed.（原文中说了）

那么要用到装配工（assemblers）去装配television的数量就减少了三（简单的数学关系）

However, recent statistics show a droip in the number of television assemblers

the number of television needed to be assembled = the number of assembler workers × the average time

前提就是 C the average time 不变

由于三年前B降低了V的关税,每年在B销售的TV没有变化（这句话什么意思？）

意思就是，总的TV销售量没有变（总的TV销售量=进口的数量+自己生产的） （ps：我认为自己生产的才需要assemble）
