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?
老师： 老管上课讲逻辑下对上的题型的时候说逻辑承认的是选项对，所以逻辑的选项的范围可以超出原文的范围。但是您讲的是如果范围不对就要干掉，这怎么解释啊？求教。 顺便再问道题目哈。这道题留下BE选项。B选项我读出来的意思是这个限制导致。。。的后果已经很多年了。原文没说关于多少年的问题啊，就排除了。而E说 snow geese 没有天敌，我把它放到原文里，觉得能使我对结论的相信度增加啊，就说其他可能导致snow geese 数量增加的原因排除了，就选了E，请老师指正。
