Environmental organizations want to preserve the land surrounding the Wilgrinn Wilderness Area from residential development. They plan to do this by purchasing that land from the farmers who own it. That plan is ill-conceived: if the farmers did sell their land, they would sell it to the highest bidder, and developers would outbid any other bidders. On the other hand, these farmers will never actually sell any of the land, provided that farming it remains viable. But farming will not remain viable if the farms are left unmodernized, and most of the farmers lack the financial resources modernization requires. And that is exactly why a more sensible preservation strategy would be to assist the farmers to modernize their farms to the extent needed to maintain viability. In the argument as a whole, the two boldface proportions play which of the following roles? A. The first presents a goal that the argument rejects as ill-conceived; the second is evidence that is presented as grounds for that rejection. B. The first presents a goal that the argument concludes cannot be attained; the second is a reason offered in support of that conclusion. C. The first presents a goal that the argument concludes can be attained; the second is a judgment disputing that conclusion. D. The first presents a goal, strategies for achieving which are being evaluated in the argument; the second is a judgment providing a basis for the argument’s advocacy of a particular strategy. E. The first presents a goal that the argument endorses; the second presents a situation that the argument contends must be changed if that goal is to be met in the foreseeable future.
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 year’s record pace. At the same time, there is considerable evidence that the number of new companies starting up this year will be no higher 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 year’s record. In the argument given, the two portions in boldface play which of the following roles? A. The first provides evidence in support of the main conclusion of the argument; the second is a claim that argument challenges. B. The first is a generalization that the argument seeks to establish; the second is a conclusion that the argument draws in order to support that generalization. C. The first is a generalization that the argument seeks to establish; the second is a judgment that has been advanced in order to challenge that generalization. D. The first is presented as obvious truth on which the argument is based; the second is a claim that has been advanced in support of a position that the argument opposes.
E. The first is presented as obvious truth on which the argument is based; the second is a judgment advanced in support of the main conclusion of the argument.
Whales originated in the freshwater lakes and rivers of ancient Asia about sixty million years ago. Not until about ten million years later did species of whales develop specialized kidneys enabling them to drink salt water. Although fossil evidence shows that some early whale species that lacked such kidneys sometimes swam in the Earth’s saltwater oceans, these species must have had to return frequently to freshwater rivers to drink. Which of the following is most strongly supported by the information given? A. Fossils of whale species dating from between sixty million and fifty million years ago will not be found on continents that were at the time separated from ancient Asia by wide expanses of ocean. B. Among whale fossils that date from later than about fifty million years ago, none are fossils of whale species that drank only fresh water. C. Fossils of whale species that drank fresh water will not be found in close proximity to fossils of whale species that drank salt water. D. The earliest whales that drank salt water differed from fresh-water-drinking whales only in their possession of specialized kidneys. E. Between sixty million and fifty million years ago, the freshwater lakes and rivers in which whales originated were gradually invaded by salt water.
Which of the following most logically completes the argument? Yorco and Zortech are two corporations that employ large numbers of full-time workers who are paid by the hour. Publicly available records indicate that Yorco employs roughly the same number of such hourly wage workers as Zortech does but spends a far higher total sum per year on wages for such workers. Therefore, hourly wages must be higher, on average, at Yorco than at Zortech, since _____ A. Zortech spends a higher total sum per year than Yorco does to provide its hourly wage workers with benefits other than wages B. the work performed by hourly wage workers at Zortech does not require a significantly higher level of skill than the work performed by hourly wage workers at Yorco does C. the proportion of all company employees who are hourly wage workers is significantly greater at Yorco than it is at Zortech D. overtime work, which is paid at a substantially higher rate than work done during the regular work week, is rare at both Yorco and Zortech E. the highest hourly wages paid at Yorco are higher than the highest hourly wages paid at Zortech
