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?
Hunting limits for snow geese were imposed many years ago in response to a sharp decline in the population of snow geese.
It has been many years since the restriction led to the hunting season for snow geese being closed earlier than the scheduled date.
The number of snow geese taken by hunters each year has grown every year for several years.
As their population has increased, snow geese have recolonized wintering grounds that they had not used for several seasons.
In the snow goose's winter habitats, the goose faces no significant natural predation.
sg 数量猛增影响了其他物种
方案：取消sg的捕猎限制 ➡️ goal：其他物种恢复
B 方案可行性
没看懂，实际意思是 sg捕杀数量一直没有达到总数量的5% 所以好多年都没有提前取消限制
D sg数量增多占据地盘 ❌ 想当然地把占地盘&影响其他物种联系在一起
没有涉及对方案的评估
