11. GWD17-Q11:
Some species of Arctic birds are threatened by recent sharp increases in the population of snow geese, which breed in the Arctic and are displacing birds of less vigorous species.Although snow geese are a popular quarry for hunters in the southern regions where they winter, the hunting season ends if and when hunting has reduced the population by five percent, according to official estimates.Clearly, dropping this restriction would allow the other species to recover.
Which of the following, if true, most seriously undermines the argument?
A.Hunting limits for snow geese were imposed many years ago in response to a sharp decline in the population of snow geese.
B.It has been many years since the restriction led to the hunting season for snow geese being closed earlier than the scheduled date.
C.The number of snow geese taken by hunters each year has grown every year for several years.
D.As their population has increased, snow geese have recolonized wintering grounds that they had not used for several seasons.
E.In the snow goose’s winter habitats, the goose faces no significant natural predation.
Answer: B, My choice: D
不明白，感觉每次打猎季提前结束的话，说明如果没有限制，那么snow geese的数量应该降低更多，那的确可以让别的物种数量增加，这样不反而是支持结论了吗？
28. GWD-18-Q20
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.
Answer: D, My choice: B
