天山-3-24（以前没讨论过）

这个题目要理解结论的特殊性，to set out small amounts of poisoned rice during the blackbirds’ spring stop in order to reduce the fall blackbird population

既然是减少blackbird population，B和C显然对所有的鸟都有影响，所以不对。

強烈支持C。

rare migratory bird 應該是指留鳥。也就是說這些鳥是不走的。不管red-winged blackbird是不是第一個到達的候鳥﹐rare migratory bird都已經在當地了。所以這些留鳥是可能第一個吃米的。當地人關心的是毒米會不會影響這些留鳥。所以C指明這些留鳥不吃毒米。應是正確答案。

至於其它候鳥是不是也吃毒米﹐ 這並不是residents關心的。注意理解文章。

Using SC rules, rare migratory bird, rare modifies migratory, migratory modifies bird.   if it were to mean that the bird is rare, it would say something like "migratory brid that is rare"

Here it would mean native bird.

A: we do not know that red-winged blackbirds would finish the poison rice or even eat the rice.

C: few species of "rare migratory bird" (native to the province) eat rice

rare和migratory并列修饰bird 是稀有的迁徙鸟类.

如果rare修饰migratiory那应该用rarely吧.

答案应该是A.

A项对。题目透露红鸟食量非常大“significant portion of the province’s sunflower crop”，而毒米少“small amounts of poisoned rice”，所以红鸟会把毒米吃光，其它鸟不会受到影响。

ls所言极是，自己做的时候就没有想到“significant portion of the province’s sunflower crop”，这句话隐藏的含义——red winged blackbird食量很大。现在看来A选项没有什么漏洞了！

那么本地的鸟会不会吃毒大米呢？A还要假设一下本地的鸟不吃大米？或者本地没有鸟？

谢谢，终于觉得A不怪了

The right choice should be A.

C completely has nothing to do with the argument, the rare migratory birds is not the birds which would stay in the same places for ever, but the birds have a small amount and migrate too.
