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?
这题我读出来的意思是：blackbirds是春天和秋天迁徙的，他们吃向日葵的种子。今年农民寻求允许，放置一些有毒的大米在blackbirds春天停留的时候以减少秋天blackbirds的数量。一些人说这种有毒的大米会危害很少迁徙的鸟类。但是，一个机构允许了这种做法。 题目要求是找出支持这个机构的做法，即支持农民说放有毒大米减少blackbirds的数量。 我选了B，B说的是这种毒药对鸟没有影响，但是会让他们不能生蛋，虽然说可能会发散到不能生蛋导致数量少，但是我认为这个是最沾边的。 而答案中的A说这种blackbirds是第一个鸟在这个地方，我认为无关。
