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?

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.

Answer: B

B是怎么削弱的啊，可能没看懂题。。。

题目主要是说北极鸟被最近迅速增长的雪鹅所威胁.

尽管雪鹅是南部猎人喜欢的猎物,根据官方估计.如果狩猎已经导致雪鹅数量减少5%,狩猎季节就结束了 .显然,家少百分比的限制将导致其他种类的恢复.

是个措施达目的的题目,在5个选项中选一个说措施不可行的来削弱.

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.提出过去狩猎限制出现的愿意,无关

It has been many years since the restriction led to the hunting season for snow geese being closed earlier than the scheduled date.正确.说由于限制导致雪鹅的狩猎季节提前结束.意思是第一年100只,5%是5只,用1个月,第二年按5%的限制来捕杀只用了半个月,提前结束狩猎期,也许总量减少了50只,5%只是2-3只,所以只用半个月.虽然比较牵强但也只能用这个.

The number of snow geese taken by hunters each year has grown every year for several years.说绝对数已经增长了很多年,无关.比如第一年鹅总数100只,杀5只5%,单第二年总数200只,10只5%,只说绝对数增加没有任何影响

As their population has increased, snow geese have recolonized wintering grounds that they had not used for several seasons.提到在其他地方繁殖,无关

In the snow goose’s winter habitats, the goose faces no significant natural predation.

无关

A good reasoning: (quote from https://www.veritasprep.com/blog/2015/11/critical-role-reading-gmat-critical-reasoning/)

Choice B
What does this option really mean?

Does it mean the hunting season has been closing earlier than the scheduled date for many years? Or does it mean the exact opposite, that the restriction came into effect many years ago and since then, it has not come into effect.
... The correct meaning is the second one – the restriction has not come into effect for many years now. This means the restriction doesn’t really mean much.

... Whether you have the restriction or not, the number of geese hunted is the same. So even if you drop the restriction and tell hunters that they can hunt as much as they want, it will not help as they will not want to hunt geese much anyway. This implies that even if the restriction is removed, it is likely that there will be no change in the situation. This definitely weakens our conclusion that dropping the restriction will help other species to recover.
