GWD5-Q3:
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. 正确答案是C 但是我觉得没什么道理啊
GWD5-Q30: Which of the following most logically completes the argument?
The irradiation of food kills bacteria and thus retards spoilage. However, it also lowers the nutritional value of many foods. For example, irradiation destroys a significant percentage of whatever vitamin B1 a food may contain. Proponents of irradiation point out that irradiation is no worse in this respect than cooking. However, this fact is either beside the point, since much irradiated food is eaten raw, or else misleading, since _______.
A. many of the proponents of irradiation are food distributors who gain from food’s having a longer shelf life B. it is clear that killing bacteria that may be present on food is not the only effect that irradiation has C. cooking is usually the final step in preparing food for consumption, whereas irradiation serves to ensure a longer shelf life for perishable foods D. certain kinds of cooking are, in fact, even more destructive of vitamin B1 than carefully controlled irradiation is E. for food that is both irradiated and cooked, the reduction of vitamin B1 associated with either process individually is compounded 正确答案是E 但是说实话，我没看懂题意……
Editorial in Krenlandian Newspaper: Krenland’s steelmakers are losing domestic sales because of lower-priced imports, in many cases because foreign governments subsidize their steel industries in ways that are banned by international treaties. But whatever the cause, the cost is ultimately going to be jobs in Krenland’s steel industry. Therefore, it would protect not only steel companies but also industrial employment in Krenland if our government took measures to reduce cheap steel imports.
Which of the following, if true, most seriously weakens the editorial’s argument?
A. Because steel from Krenland is rarely competitive in international markets, only a very small portion of Krenlandian steelmakers’ revenue comes from exports. B. The international treaties that some governments are violating by giving subsidies to steelmakers do not specify any penalties for such violations. C. For many Krenlandian manufacturers who face severe international competition in both domestic and export markets, steel constitutes a significant part of their raw material costs. D. Because of advances in order-taking, shipping, and inventory systems, the cost of shipping steel from foreign producers to Krenland has fallen considerably in recent years. E. Wages paid to workers in the steel industry in Krenland differ significantly from wages paid to workers in many of the countries that export steel to Krenland. 正确答案是C，但是我觉得没有什么说服力 或者说，要拐个弯才能削弱…… |
