l care.( the position that the city official’s argument opposes ) However, this conclusion is almost certainly false. (the conclusion of the city official’s argument ) Careful investigation has recently shown two things: insured patients have much longer stays in the hospital than necessary, and they tend to have more procedures performed than are medically necessary. (Evidence) GWD3Q2 Hunter: Hunters alone are blamed for the decline in Greenrock National Forest’s deer population over the past ten years. Yet clearly, black bears have also played an important role in this decline. (the main conclusion of the argument) In the past ten years, the forest’s protected black bear population has risen sharply, and examination of black bears found dead in the forest during the deer hunting season showed that a number of them had recently fed on deer. (Evidence) GWD3Q16: Economist: Tropicorp, which constantly seeks profitable investment opportunities, has been buying and clearing sections of tropical forest for cattle ranching, although pastures newly created there bee useless for grazing after just a few years. The pany has not gone into rubber tapping, even though greater profits can be made from rubber tapping, which leaves the forest intact. (supports the environmentalists’ conclusion) Thus, some environmentalists conclude that Tropicorp has not acted wholly out of economic selfinterest. (states that environmentalists’ conclusion) However, these environmentalists are probably wrong. The initial investment required for a successful rubbertapping operation is larger than that needed for a cattle ranch. Furthermore, there is a shortage of workers employable in rubbertapping operations, and finally, taxes are higher on profits from rubber tapping than on profits from cattle ranching. GWD5Q19: Historian: In the Drindian Empire, censuses were conducted annually to determine the population of each village. Village census records for the last half of the 1600’s are remarkably plete. (provides a context for certain evidence that supports the position that the historian seeks to establish) This very pleteness makes one point stand out。 in five different years, villages overwhelmingly reported significant population declines. Tellingly, each of those five years immediately followed an increase in a certain Drindian tax. This tax, which was assessed on villages, was puted by the central government using the annual census figures. Tellingly: 有效地。 顯著地 Obviously, whenever the tax went up, villages had an especially powerful economic incentive to minimize the number of people they recorded。 and concealing the size of a village’s population from government census takers would have been easy. Therefore, it is reasonable to think that the reported declines did not happen. (that position) GWD5Q20: Scientists typically do their most creative work before the age of forty. It is monly thought that this happens because aging by itself brings about a loss of creative capacity. (an explanation that the argument challenges) However, studies show that a disproportionately large number of the scientists who produce highly creative work beyond the age of forty entered their field at an older age than is usual. (a finding on which that challenge is based) Since by the age of forty the large majority of scientists have been working in their field for at least fifteen years, the studies’ finding strongly suggests that the real reason why scientists over forty rarely produce highly creative work is not that they have simply aged but rather that they generally have spent too long in a given field. 天山 Q25: Scientists typically do their most creative work before the age of forty. It is monly thought that this happens because aging by itself brings about a loss of creative capacity. (an explanation that the argument challenges) However,。
