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.

选B.错选D.不是很懂...请大家帮忙指点~~谢谢~~

 逻辑链条

recent sharp increase导致了 some species are threaten

所以为了 allow species 复苏 必须  减少 recent sharp increase

也就是找出recent sharp increase的原因

原文认为  restriction是引起 recent sharp increase的原因

那么我们只要证明restriction不是引起recent sharp increase的原因

B刚好证明了这点

这才是真正的逻辑链

我觉得这句话中间少了个条件

the hunting season ends...if... and when hunting has reduced the population by five percent

Ｄ　as 条件不对，无关

B B.    It has been many years since the restriction led to the hunting season for snow geese being closed earlier than the scheduled date而other species 还是下降，　结论：dropping this restriction would allow the other species to recover.

 是断桥！

 是断桥！

但是drop this restriction之后，导致的是其他 species增加的话，怎么是weaken呢？

我觉得没一个答案对

我将题目大致翻译了一下，大家一起来讨论。

1）一些在极地生活的鸟类受到了雪鹅数量急剧增加的威胁。2）这些雪鹅又是捕猎者所喜爱的猎物。3）捕猎禁令规定了每当官方估计雪鹅数量减少了5%当年的捕猎就必须结束。4）所以，作者认为取消5%的限令将有助于其他鸟类的生存（因为雪鹅数量会因为不受限制的捕猎而减少）

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

多年来，对雪鹅的狩猎季节总是要比预期的提前结束。

也就是说捕猎的人们其实对雪鹅不是特别感兴趣，在雪鹅数量没有减少5%前，狩猎者们就停止捕猎了。所以，即使取消禁令，也不会使雪鹅的数量下降。

欢迎讨论。

提早结束不正是说明是因为数量介绍超过5%吗？不知道LS是从哪里看到没有兴趣的？

欢迎讨论，我也是选D

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

仔细理解一下这句话。

It has been many years since i visited Paris

就是说我参观巴黎是很久之前的事情了。

所以，这里说的是：“禁令让狩猎季提早结束” 也是很多年前的事情了。

就是说现在已经不可能提早结束了。

就是说我现在放开让你们去打猎，你们也打不到5%。

B 是说多年以来，猎鹅都会比官方规定的结束时间提前结束。结束的原因当然是因为对雪鹅的捕杀量已经达到，或超过了5%，所以要提前结束。 比如猎鹅从3月开始到6月结束，那么在4月时捕杀量就已经达到5%了，所以在4月猎鹅季节就被官方提前强制结束了。 提干中说如果取消5%的猎杀限制，就会使其他物种复苏，在这个例子中也就是说，如果猎鹅季节不会因为捕杀量超过5%就提前结束的话，那么在6月结束时，雪鹅的减少量必然会超过5%，所以其他鸟就可以复苏了。

所以B是加强。

不知道我说明白没有......
