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. 答案选B为什么我觉得B是support了呢
the hunting season ends if and when hunting has reduced the population by five percent, according to official estimates这个restriction的作用是在snow geese被打猎到降低5%数量时停止打猎期 C.The number of snow geese taken by hunters each year has grown every year for several years.这项说猎人能达到的snow geese的数量连续几年增长,说明5%对应的数字在增长,乘数变大,说明即使有5%的restriction时snow geese数量也在增长啊,从而undermine
原文论点: 放弃这项限制将有助于其他生物存活 论据:这个限制是决定打猎季节终止的标志,也就是正因为有这个限制,打猎才收到限制 题目问:哪个削弱了。。也就是。这个限制对于真正的打猎时间是没有作用的。。。 B其实是一个语法问题。。。举个例子说 it has been a long time since we met each other last time...是说我们好久都没见面了。。B说的是。。。自从限制对打猎时间的控制还生效的。。。已经很久了。。也就是。。限制对打猎时间的终止没有影响。。已经很久了。。
It has been many years since the restriction led to the hunting season for snow geese being closed earlier than the scheduled date. ------- led to表明了很多年以前restriction就已经不再导致狩猎期提前结束了。
B. It has been many years since the restriction led to the hunting season for snow geese being closed earlier than the scheduled date. B是说这个blabla...的限制已经实施很多年了。
