【OG20-P798-825题】Many utilities obtain most of their electric power from large coal and nuclear operations at costs that are sometimes two to three times higher as that of power from smaller, more efficient plants that can both make use of waste heat and take advantage of the current abundance of natural gas.
【OG20-P599-730题】In countries where automobile insurance includes compensation for whiplash injuries sustained in automobile accidents, reports of having suffered such injuries are twice as frequent as they are in countries where whiplash is not covered. Presently, no objective test for whiplash exists, so it is true that spurious reports of whiplash injuries cannot be readily identified. Nevertheless, these facts do not warrant the conclusion drawn by some commentators that in the countries with the higher rates of reported whiplash injuries, half of the reported cases are spurious. Clearly, in countries where automobile insurance does not include compensation for whiplash, people often have little incentive to report whiplash injuries that they actually have suffered.In the argument given, the two boldfaced portions play which of the following roles?
【OG20-P590-701题】Last year a record number of new manufacturing jobs were created. Will this year bring another record? Well, any new manufacturing Job is created either within an existing company or by the start-up of a new company. Within existing firms, new jobs have been created this year at well below last years record pace. At the same time, there is considerable evidence that the number of new companies starting up will be no higher this year than it was last year and there is no reason to think that the new companies starting up this year will create more jobs per company than did last year's start-ups. So clearly, the number of new jobs created this year will fall short of last years record.In the argument given, the two portions in boldface play which of the following roles ?

Which of the following plans, if feasible, would allow a company to prepare most effectively for the rapid obsolescence of skills described above?
【OG20-599-728题】Exposure to certain chemicals commonly used in elementary schools as cleaners or pesticides causes allergic reactions in some children. Elementary school nurses in Renston report that the proportion of schoolchildren sent to them for treatment of allergic reactions to those chemicals has increased significantly over the past ten years. Therefore, either Renston's schoolchildren have been exposed to greater quantities of the chemicals, or they are more sensitive to them than schoolchildren were ten years Ago.Which of the following is an assumption on which the argument depends?
Roland: The alarming fact is that 90 percent of the people in this country now report that they know someone who is unemployed. Sharon: But a normal, moderate level of unemployment is 5 percent, with one out of 20 workers unemployed.
