OG12-112 请教思路

112.

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.

Argument Construction

Situation Television assemblers in Vernland are paid less than those in neighboring Borodia. The number of televisions sold in Borodia has not dropped since its tariff s on Borodian TVs were lowered three years ago, but the number of TV assemblers in Borodia has. So TV imports from Vernland have likely increased.

Reasoning What assumption does the argument depend on? The fact that fewer individuals in Borodia are working as TV assemblers is offered as evidence that TV imports from Vernland into Borodia have likely increased. That piece of evidence is relevant only as an indication that the number of TVs being produced within Borodia has decreased. But a drop in the number of TV assemblers does not indicate a drop in the number of TVs being assembled if the number of TVs an average assembler puts together has increased. Thus, the argument must be assuming that the average time it takes an assembler to put together a TV has not significantly decreased.

这题我是用排除法选出的c。。但还是不是很明白assumption的方法。。

我的思路是：

B国卖的电视数量没有下降，但装配电视的工人人数下降了，得出结论：B从V进口了电视

进一步就是B国内自己生产的电视数量下降了，所以假设就是：B国装配工装配电视的时间没有下降，因为是装配工人数的下降，才导致国内生产的电视数量下降了，才从V国进口。。如果装配工装配电视的时间缩短了，尽管装配工人数下降，也可以装配出同样的数量的电视，而不需要从V国进口了。。

我不知道这样的思路对不对。。还请大家帮我分析分析~~~~谢谢

选Ｃ吧

结论：从Ｖ到Ｂ的电视将会增加

evidence：Ｂ国的assemblerｓ减少了，且从三年前Ｂ减少了V的电视关税后，B的电视数量没变

因为B的电视数量没变，而V到B的电视增加，则假设是B的电视产量下降

将电视产量和assemblers联系起来就是，assemblers的效率没有增加

如果组装工人效率增加则，人数减少不一定会导致电视产量减少，则V到B的电视增多就不成立了

assumption方法就是

将答案取非之后是削弱原结论的
