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?

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.

考题讲解

毕出

情景：Vernland的电视装配工人的每小时工资比Borodia的低。自从3年前Borodia减小了对Vernland的电视关税，每年Borodia的电视销售量没变。然而，最近数据表明Borodia电视装配工的数量减少。因此，统计数据显示Borodia每年从Vernland进口的电视数量增多。

推理：由于前提和结论讨论的是两件事，并且结论为因，因此本题为果因推理。
顺序的因果逻辑：因为Borodia每年从Vernland进口的电视数量增多，所以在Borodia的电视销售量没变的情况下，Borodia电视装配工的数量减少
（果）前提：在Borodia的电视销售量没变的情况下，Borodia电视装配工的数量减少
（因）结论：Borodia每年从Vernland进口的电视数量增多

选题方式：果因推理有两个评估方向，简而言之，即（由于本题问的是假设，所以答案选项需在“取非”后满足），要么给“在Borodia的电视销售量没变的情况下，Borodia电视装配工的数量减少”另一个原因，要么给出因果联系问题。

选项分析：

A选项：Vernland装配工数量的增长率至少和Borodia装配工数量的减少率相等。Vernland的装配工是否有数量的增加和本题的因果无关。

B选项：Vernland生产的电视有Borodia生产的电视所不具备的特征。本选项可以解释为什么Borodia会从Vernland进口，但是不能解释“Borodia电视装配工的数量减少”。

C选项：Correct. 近3年，Borodia电视装配工生产电视所需的平均时间没有减少。本选项可以解释为什么虽然Borodia电视装配工的数量减少，但是产量可以不变，即，是因为每个装配工的效率上升了。属于CQ2：说明结果问题。

D选项：近3年，Vernland生产的电视增多。Vernland生产的电视无论有多少，都不一定要进口到Borodia去。

E选项：Borodia和Vernland的电视装配工的每小时工资差额越来越小。本选项和推理文段的因果无关。
