GWD17-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?

 

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B,我选的A,看不太懂答案什么意思

还有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.这句话好像不通啊

谢谢各位啦~~

考场上

第一步，问题问削弱

第二步，看题干，说有些北极的鸟被锐减的SG的数量威胁，这个SG以北极鸟为食料。虽然SG是什么猎人的什么，然后少了5%。结论是drop调禁令就可以让其他种族恢复什么的。

第三步，看问题

A我也没看懂什么意思

B说禁令导致猎季SG早于什么SD

C说SG数目每年被猎人打的增加，无关答案，杀

D看到had not used发现范围不对，杀

E野马，杀

AB开比吧

A在说HL为什么被impose，B说禁令怎么着了已经多年

和题干更直接的是B

做完
