Q3:不明白是怎么做，请赐教！！

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?

 

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.

the number of televisions sold annually in Borodia has not changed.  电视机数量没变

 

recent statistics show a droip in the number of television assemblers in Borodia.  工人少了

 

结论: the number of televisions Borodia imports annually from Vernland has increased.  电视机进口增加了

 

问假设

 

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.  工人生产电视机的时间没有减少. 

 

题目中已经说了工人减少了, 如果生产效率没有提高的话, 那么生产的数量就减少. 而总量不变, 所以才可以推出结论是进口增加
