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.

答案选C，但我觉得C中不应该说not decrease,而应该是not increase, 如果是按C中所说，效率没有减少，那么可能是不变或者是增加，如果效率不变，会得到conclusion,但如果效率增加，且增加的足以不需要进口，那么conclusion不成立。只有说效率没有增加，即not increase 才能成为假设，因为没有增加就是不变或者降低，都可以得到conclusion。所以我觉得C选项不对啊，求解答

not decrease不是效率没有减少，是时间没有减少，意思是效率不变。

number of televisions sold annually in Borodia has not changed总量不变
a drop in the number of television assemblers in Borodia B工人减少
推出 the number of televisions Borodia imports annually from Vernland has increased 进口增加
assumption是排除他因。选C
