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.

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.

还有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.这句话好像不通啊

答案B,我选的A,看不太懂答案什么意思

谢谢各位啦~~

第二步，看题干，说有些北极的鸟被锐减的SG的数量威胁，这个SG以北极鸟为食料。虽然SG是什么猎人的什么，然后少了5%。结论是drop调禁令就可以让其他种族恢复什么的。
