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?

 

1. In the region where the red-winged blackbirds stop, they are the first birds to be present in the spring.
2. The poison that farmers want to use does not kill birds but rather makes them incapable of producing viable eggs.
3. Since rice is not raised in Midland Province, few species of birds native to the province normally eat rice.
4. Without the permit, any farmers shown to have set out poison for the blackbirds would be heavily fined.
5. The poison that farmers got approval to use has no taste or smell that would make it detectable by birds.

为什么A比C更好，自己觉得，C更贴切RARE MIGRATORY BIRDS。请指点，谢谢

huh,though the statement in choice C can easily support the wildlife agency's approval, it oppose to the premise about Some residents voiced concern . note the words in the question, "given the concerns voiced by some residents", that suggest, this concern is valid. Choice C argues against this point and hence is not right answer.

题做多了，习惯性的去选择推翻驳斥支持结论。  还是要仔细读题啊
