Critical Reasoning

试题详情

题目:

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?

选项:

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 makes 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.

答案:

A

提问:

justify是支持的意思吗,E为什么不对

提问:

这题我选了C,题干中说到,Some residents有一些担忧,有毒大米会危害不迁徙的鸟(species of rare migratory birds),C中说当地鸟不吃大米就比较吻合了。A说的是这帮黑鸟会第一个到因此会先吃掉,但是不迁徙的鸟不是一直在这个区域么?

提问:

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。

提问:

就是关于A,B选项,A选项和原文有关因为提到了鸟的出现,所以留下,这点我能理解。关键是B,按英杰老师说法B和原文是无关的,直接扔了,但鄙人认为B选项提到的是用这种毒药有什么样的效果,和原文中的set out small amounts of poisoned rice during the blackbirds' spring stop in order to reduce the fall blackbird population. 这句话不谋而合,因为原文这句话提到的也是毒药的效果及目标。所以,B选项肯定有关的啊,这样留下AB两个选项进行比较,这时根据比较的原则,1。哪个发散少2。哪个回答问题,而根据原文最后提到rice could threaten certain species of rare migratory birds来看,肯定是B选项更直接了,A选项就相对离得较远。选B 此题答案为A,但本人实在不知上述思考方式出现了何种纰漏,请老师解答
