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.

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.这句话基本就是不明白...
答案是B，有人能帮助解释一下吗？感激！

Ithas been many years since是很久以前的意思。It has been many years since I went to Paris
. 很久以前我曾经去过巴黎，已经是历史了。B说，现在已经不会出现这种情况了：由于限制的原因导致hunting提前结束。就是说hunting不会因为限制的原因提前结束，而提前结束是因为SG数量减少了5%，所以说hunting不会使得SG数量减少5%à人们不喜欢打猎SG了。所以人们不喜欢打猎SG，即使放开限制，可以多多的捕杀SG，SG的数量不会下降，other species也因此不会recover，削弱。

我有问题，可是你的解释和原句中的一句话是矛盾的，原文中说SG are popular quarry的。：Although snow geese are a popular quarry for hunters in the southern regions where they winter,


请进一步赐教～
谢谢！

请教下，看了你的分析，你是对所说的B答案取反是吗？这类题都这样做？还是it has been......句式本身有翻译的成分？
