112. The average hourly wage of television assemblers in Vernland has long been signifi cantly 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 theargument 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 nothave.
(C) The average number of hours it takes a Borodian television assembler to assemble a television has not decreased signifi cantly during the past
three years.
(D) The number of televisions assembled annually in Vernland has increased signifi cantly 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.

因为C确定了另一个条件，就是本国工人的电视机生产效率没有变化。
消费数量没有变，本国生产在工人减少的情况下，效率没有变化，加上关税减了，那就能自然推出进口多了。
