1.

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?

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.

恩，好像在OG上做过这个题，VERBAL分册上的貌似。

这个答案的ASSUMPTION是DEFENSIVE ASSUMPTION，即假设没有其他原因导致结果，那么原文argument的结论正确。

C是对的！

v城中a人干a活比B城中a人干a活小时工资低，B城三年前取消对V城的税，B卖的电视节目数不变。但是近期显示，B城a人少了。说明B城进口多了。
电视节目数不变，干这个活的人少了，如果效率还是差不多的话，那只能是进口电视节目了

Premise: Televisions are made in both V and B, and B imports TV from V.  The number of televisions sold in B keeps constant.  These TV's come from both B and V. the number of TV assemblers in B decreases.

Conclusion: TV imports from V to B has increased.

The assumption is that if TV assemblers in B are fewer, there will be fewer TV made in B.  A further assumption is that the efficiency of TV assemblers in B has not changed (answer C).

If you use negation method, you would find that after negating C, the argument falls apart. If assemblers in B become more efficient, they can produce the same amount or more TV than before, even with a lower number of total assemblers.
