GWD-3-Q2
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)
GWD-3-Q16:
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 become useless for grazing after just a few years.
The company 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 self-interest. (states that environmentalists’ conclusion)
However, these environmentalists are probably wrong.
The initial investment required for a successful rubber-tapping operation is larger than that needed for a cattle ranch.
Furthermore, there is a shortage of workers employable in rubber-tapping operations, and finally, taxes are higher on profits from rubber tapping than on profits from cattle ranching.
GWD-5-Q19:
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 complete. (provides a context for certain evidence that supports the position that the historian seeks to establish)
This very completeness 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 computed 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)
