11. 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? (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.



13. GWD-18-Q13

Eurasian watermilfoil, a weed not native to Frida Lake
, has reproduced prolifically since being accidentally introduced there.In order to eliminate the weed, biologists proposed treating infested parts of the lake with a certain herbicide that is nontoxic for humans and aquatic animals.However, the herbicide might damage populations of certain rare plant species that the lake contains.For this reason local officials rejected the proposal.



Which of the following, if true, points out the most serious weakness in the officials’ grounds for rejecting the biologists’ proposal?（A）



A.The continuing spread of Eurasian watermilfoil in Frida Lake
threatens to choke out the lake’s rare plant species.
B.Because of ecological conditions prevailing in its native habitat, Eurasian watermilfoil is not as dominant there as it is in Frida Lake
.
C.The proliferation of Eurasian watermilfoil in Frida Lake
has led to reductions in the populations of some species of aquatic animals.
D.Although Eurasian watermilfoil could be mechanically removed from Frida Lake
, eliminating the weed would take far longer this way than it would using herbicides.
E.Unless Eurasian watermilfoil is completely eliminated from Frida Lake
, it will quickly spread again once herbicide treatments or other control measures cease.
关于11题b选项，它说比预期的休猎期提前了，不就意味着人们都很喜欢打猎，很快就把允许打猎的5%给打完了吗？这样要是把打猎的上线取消，不就会打更多的猎了吗？怎么像是加强啊？12题也不是很明白……有哪位NN帮忙解释一下嘛？

预期的休猎期提前了——》不就意味着人们都很喜欢打猎：楼主，你太主观了，可能结果很多。
人们都很喜欢打猎——》很快就把允许打猎的5%给打完了：楼主：你再次主管，喜欢打猎，如果枪法不准的话，是不是就打不完呢？或者说5%的量是个很夸张的数字（如果基数大），到死都打不完呢（比如猎人少）？

多些楼上，明白了~

打不完为什么会关闭狩猎季节呢？

题中有一个很强的引导，hunting season ends if reduced 5 percent。所以我们知道的狩猎季节关闭的原因，不带入外部知识，只能是因为打到上限了啊。
