求解释
Question:SomespeciesofArcticbirds are threatened by recent sharp increase 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 5 percent,according to official estimates.Clearly,dropping this restriction would allow the other species to recover.
a.hunting limits fro 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 that 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.
请各位NN帮我分析一下这道题 非常感谢。。。 、
就是B到底说的是什么意思呢？我办老天没想出来~~~

^to ls, thanks a lot

I think "they" in "where they winter" indicates the snow geese here. "Winter" is a verb means "to spend the winter somewhere".

为神马我觉得GWD里的句子和OG的读起来不是一种感觉。。。绕死我了。请哪位大大能够分析一下题干中这句句子的结构？

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 5 percent,according to official estimates.

where they winter这个they谓语宾语是什么？
谢谢！

那也就是说  ，the restriction    hasn't  led to the hunting season for snow geese being closed earlier than the scheduled date for many years.  

对吗？也就是说，限制法律并没有导致狩猎季节比正常时间更早的结束for many years.?
有点绕了，帮忙看下啊~

It has been many years since the restriction led to the hunting season for snow geese being closed earlier that than the scheduled date.

The restriction has NOT led to the overhunting of geese for many years.

It has been many years since I visited Beijing = I have NOT been to Beijing for a long time.

As to B, you need to understand the meaning of "A  led to B."

谢谢LS， 基本明白意思了，但是对于B，我有个困惑，那个It has been many years 是修饰谁的？我看到B后理解的是:  对于geese打猎的时间的限制 比  scheduled date（不知道这个该如何确定），已经有很多年了，
我看你的答案是说5%的方面？

B means hunters could not kill more than 5% of snow geese in a hunting season for many years.

The answer is B, which claims that the restriction set has no effect on the highest number of geese killed in a hunting season.  Therefore, removing the restiction would not lead to more killings of the geese and better chances for the other species to recover. Thus, B weakens the argument.

In other words, what B says is that the 5% reduction in geese population due to hunting has never been reached for many years. Therefore, more than 5% reduction in geese population is unlikely to be reached even if such restriction is removed.
