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.
Goal:帮助其他种类的鸟恢复数量
Plan:移除‘捕猎数达到鹅的总数5%以后就终止捕猎季’的规定
GAP: 移除限制之后就能捕杀更多的雪雁
B: 禁令导致捕杀期提前结束已经过去很多年了，也就是说很多年没有提前结束捕杀期了。
提前结束捕猎期=捕猎数提前达到了规定的5%；很多年没有提前结束捕猎期=很多年捕猎数都没有达到5%或达到的很晚
那么即使取消禁令，情况并不会好转
