废话不说，先上题
In a certain wildlife park, park ranges 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 where 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 ranges have for tracking the movements of rhinoceroses in the park.
ANSWER: C
这道题我做对了，但是不知道它为什么对。只是觉得5个选项里面只有它最像正确选项。
后来越分析越模糊，甚至一度觉得B反倒比C更合适，但是B又比较像无关选项。
纠结。。
求大家指点 。。。
还有一个很弱的问题。我今天第一次做PREP，为什么VERBAL里绝大多数题都是之前做过的题，我之前只做了GWD和OG，重复率怎么这么高。。。那我还有必要再PREP么。。。 |
