Some species of Arctic birds are threatened by recent sharp increases in the population of snow geese, which breed in the
Which of the following, if true, most seriously undermines the argument? d b
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.
答案是B
我也做错了- -, 看了一下以前的帖子,觉得其实争议在于对B的理解,
It has been many years since the restriction led to the hunting season for snow
geese being closed earlier than the scheduled date.
因为restriction而导致的比截止日早结束这种情况在许多年前就消失了
题干,只要snow geese的数量减少了5%,hunting season就结束了(e.g. 1月到3月是hunting
season, 然后如果2月已经减少了5%,那么,就结束了)
选项B, 其实就是说到了3月份结束的时候也没有到5%,那么即使取消这个restriction也是没用
的,起到了削弱作用。
选项D, 说have recolonized wintering grounds ,其实是个无关选项,除非你假设这样以后
打不到了....
open to discussion
我觉得cllcchocolat的解释非常对.关键是要搞懂B选项的意思。B选项的意思是“因为restriction而导致的比截止日早结束这种情况在许多年前就消失了”
hunters根本打不到5%,所以即使取消5%这种restriction也没用,即削弱。
我同意B是对的, 但是B选项那句话的意思不是这样的吧???
应该是”限制措施导致狩猎季提前结束的这种情况已经很多年了“ 而不是这种情况很多年前就消失了啊
所以,即使取消限制措施也将不会有什么影响
这样才说得通啊
不解 楼上同意B 却是基于相反的意思理解?
