以下是引用GRASPDREAM在2007-8-25 17:48:00的发言： Q2: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.
此题的假设是（１）需求不变（２）Ｂ地区工人生产率不变,C满足第二个条件所以正确 那么我的问题是......红色标的字在这里起的是什么作用呢?????Assembler就是只生产组装电视的人么???大家指教啦~~~~不开翘中.....................................  assembler 在这里确实是组装工人的意思，红字里说the number of televisions sold annually in Borodia has not changed 就是说每年买出的电视总量是不变的，TV sum = B's assembler number * 生产率 + B从V import来的TV数量 题中说“B's assembler number” drop了，然后又说能推出“B从V import来的TV数量”increase，由这个的式子只有在B工人的生产率不变或下降的情况下才一定推出“B从V import来的TV数量”increase成立。所以选C. 这样红字部分的作用你应该也能清楚了吧。
