Each year red-winged blackbirds stop in a certain region of Midland Province on their spring and fall migration. 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 concern voiced by some residents?
A. In the region where the red-winged blackbirds stop, they are the first birds to be present in the spring.
B.The poison that farmers want to use does not kill birds but rather make them incapable of producing viable eggs.
C.Since rice is not raised in midland province, few species of birds native to the province normally eat rice.
D.Without the permit, any farmers shown to have set out poison for the blackbirds would be heavily fined
E.The poison that farmers got approval to use has no taste or smell that would make it detectable by birds.
已查阅了原有帖子，没什么讨论，请大家帮忙分析一下这题，偶怎么连问题都没看懂呢？到底是要支持谁呢？汗～～
结论是本来要用来剿灭red鸟的毒米会毒害当地珍惜鸟类。要求削弱这个。A的意思是red是第一批到达的鸟，会把毒米吃完，不会害到其他鸟。所以削弱了结论。
