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.
Plan:移除‘捕猎数达到鹅的总数5%以后就终止捕猎季’的规定
GAP: 移除限制之后就能捕杀更多的雪雁
B: 禁令导致捕杀期提前结束已经过去很多年了,也就是说很多年没有提前结束捕杀期了。
提前结束捕猎期=捕猎数提前达到了规定的5%;很多年没有提前结束捕猎期=很多年捕猎数都没有达到5%或达到的很晚
那么即使取消禁令,情况并不会好转
It has been many years since the restriction led to the hunting season for snow geese being closed earlier than the scheduled date.
It形式主语代替后面这一件事情:restriction led the hunting season being closed earlier
所以还原回来表示这件事情has been many years,读的时候误以为这件事情持续很久了,没想到要理解为 已经是很久以前的事了
方案:取消sg的捕猎限制 ➡️ goal:其他物种恢复
B 方案可行性
没看懂,实际意思是 sg捕杀数量一直没有达到总数量的5% 所以好多年都没有提前取消限制
D sg数量增多占据地盘 ❌ 想当然地把占地盘&影响其他物种联系在一起
没有涉及对方案的评估
B.由禁令所导致的猎季提早结束已经过去了很多年(但雪雁数量每减少,显然解除禁令没有用,削弱)
C.过去的几年里雪雁被猎人捕杀的数量逐年上升(无关)
D.随着雪雁数量的增加,雪雁已经在几个季节没有使用过的越冬地重新定居(无关)
E.在雪雁的冬季栖息地,雪雁不会面临明显的自然捕食。(无关)
B 之前有禁令,人们就提前结束杀snow geese, 可以推出snow geese应该很难被杀,尽管snow geese are a popular quarry for hunters, 导致人们放弃率很高,现在撤销禁令也帮不到忙

(看不懂题)
题目: 解除禁令能使得其他的鸟类数量涨回去。
方案推理选项要与方案相关。
A 禁令是什么时候颁布的。无关
B 禁令使得打猎季提前结束,这已经是很多年以前的事情了。-- 也就是说好多年还没有达到禁令的%5的猎杀数量,捕猎季就结束了。所以现在放开禁令,也没有用,因为猎杀不到%5的最大数量。
C 好多年每年猎杀的snow geese的数目都有增长。--那解除禁令的话能够杀更多的geese,增强。
D snow geese又回到了曾经被它们弃用的越冬地。 无关
E 在越冬地,没什么天敌。 无关

已经很多年没有提前了,说明这个政策并没有对猎人很大限制
方案:取消最多杀5%snow geese的限制
目标:缓解snow geese数量大幅的现状
B. 事实上该规定已经好多年没有用了,在达到限制的捕猎数量之前,捕猎期就已经结束了
(上一次)因猎杀限制而导致捕猎季节提前结束 已经过去好几年了
如果要说有许多年因为猎杀限制而导致捕猎季节提前结束的话,应该是
There are many years that the hunting season being closed earlier than the scheduled date, becuase of the restriction.
