Each year red-winged blackbirds stop in a certain region of Midland Province on their spring and fall migrations. In the fall, they eat a significant portion of the province's sunflower crop. This year Midland farmers sought permits to set out small amounts of poisoned rice during the blackbirds' spring stop in order to reduce the fall blackbird population. Some residents voiced concern that the rice could threaten certain species of rare migratory birds. Nevertheless, the wildlife agency approved the permits.
Which of the following, if true, most helps to justify the wildlife agency's approval of the permits, given the concerns voiced by some residents?
In the region where the red-winged blackbirds stop, they are the first birds to be present in the spring.
The poison that farmers want to use does not kill birds but rather makes them incapable of producing viable eggs.
Since rice is not raised in Midland Province, few species of birds native to the province normally eat rice.
Without the permit, any farmers shown to have set out poison for the blackbirds would be heavily fined.
The poison that farmers got approval to use has no taste or smell that would make it detectable by birds.
choice a, 在这种blackbird每年春天落脚的地方,这些鸟是第一批到达的候鸟。correct,说明这些鸟可以在其他候鸟来之前把毒药给吃完。
choice c, 因为大米不是本地生产的,很少有本地的鸟会去吃米。irrelevant,讨论的scope是会不会对其他候鸟造成伤害,和本地鸟无关
c。。few species of birds native to the province normally eat rice.----native
C说的是native bird不吃,所答非所问了
主要问题:读题的时候非常不仔细,囫囵吞枣的貌似看完了,其实根本没有仔细读,关键信息一个也没留意到,甚至把后面的/其他物种的鸟/理解成别的了导致半天选不出来...
A: 早撒毒米,早吃完,但存在吃不完影响后面的可能性;
B:incapable of producing 亦是threaten species.
C:Native birds 不吃不能减轻 threaten for migratory birds. 无关处理
D:无关
E:not detectable 让migratory birds更容易吃 wrong
即这种不会杀死珍贵的鸟类即可,A正确。B项说这种毒米不会杀死鸟类,但是会使鸟类吃完以后不能产卵。错误:这样还是不能反驳反对者,因为如果珍贵鸟类吃了毒米,也会受到威胁,数量以后也会减少。
是不是可以說減少了spring 但fall的還是很多這種鳥
很明顯的誤點 覺得A不好
我个人的观点,不知道对不对:blackbirds不一定会吃完所有毒米,但是因为它是第一个到来,所以是可以与其他迁徙的鸟分开的,等到其他鸟要来的时候,就不要放毒米了,这样就不会毒到其他鸟了。
c应该是无关选项吧,题目里说resident关心certain species of rare migratory birds,应该跟本地鸟没啥关系。登录 或 注册 后可以参加讨论
