In a certain wildlife park, park rangers are able to track the movements of many rhinoceroses because those animals wear radio collars. When, as often happens, a collar slips off, it is put back on. Putting a collar on a rhinoceros involves immobilizing the animal by shooting it with a tranquilizer dart. Female rhinoceroses that have been frequently recollared have significantly lower fertility rates than uncollared females. Probably, therefore, some substance in the tranquilizer inhibits fertility.
In evaluating the argument, it would be most useful to determine which of the following?
A. Whether there are more collared female rhinoceroses than uncollared female rhinoceroses in the park
B. How the tranquilizer that is used for immobilizing rhinoceroses differs, if at all, from tranquilizers used in working with other large mammals
C. How often park rangers need to use tranquilizer darts to immobilize rhinoceroses for reasons other than attaching radio collars
D. Whether male rhinoceroses in the wildlife park lose their collars any more often than the park’s female rhinoceroses do
E. Whether radio collars are the only practical means that park rangers have for tracking the movements of rhinoceroses in the park
思考了一下,怎么觉得5个答案都不对呢?
NN帮忙理下逻辑关系,本人已经晕了。。
帮忙顶下,同问,答案是B么?

答案给的C。C我也觉得有点儿漏洞,讲不通,NN快来解释一下!!
马上考了,纠结死了。。
我说一下我的理解不知道对不对,仅供参考
根据c所说,假如犀牛要经常因为其他原因打麻药的话,那么由于带项圈导致的打麻药的区别就大大减小甚至可以忽略了,假如犀牛不经常因为其他原因打麻药,那么这个区别就是显著的,因此有可能是因为麻药的原因造成了两种(带项圈和不带项圈)的犀牛的差异。
其他都是无关,所以选c
最近我做题也是,觉得好多题都选不出答案,然后就一堆一堆的错,简直要疯了

有道理哦。
我觉得最先开始做逻辑是题目看不懂做不起,到后来就是题目完全能看懂,但是因为逻辑链条埋得太深一时转不过弯选错。。
不知道真实考试的时候会是什么情况,我一直秉承着“只要能理解题意基本上就OK”的想法来做题,想不到还是有这种恼人的“看懂做不对”的情况(可惜)
这道题刚看的的时候其实我看不懂……,然后用了金山词霸再加上知道答案之后再进行的推理……
不过回头一看其实本题的无关都很明显,我打算考试时实在不会就用无关加猜,哈哈
