GWD 5-Q3 我怎么想还是觉得A对，为什么答案是C？

GWD5-Q3:

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?

1. The number of television assemblers in Vernland has increased by at least as much as the number of television assemblers in Borodia has decreased.

2. Televisions assembled in Vernland have features that televisions assembled in Borodia do not have.

3. The average number of hours it takes a Borodian television assembler to assemble a television has not decreased significantly during the past three years.

4. The number of televisions assembled annually in Vernland has increased significantly during the past three years.

5. 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.

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.

说的是V和B城市TA数量的增加和减少的关系

原文说的是工人hourlywage的事情, 而且虽然有增加和减少,但是没有增加和减少的关系, 所以无关.

C里面,当时好像是这么想的, hourly wage包含hour, wage两个概念, 所以The average number of hours这件事情和原文最相关. 选C
