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
Newspaper editorial:
In an attempt to reduce the crime rate,the governor is getting tough on criminals and making prison conditions harsher.Part of this effort has been to deny inmates the access they formerly had to college-level courses.However,this action is clearly counter to the governor's ultimate goal,since after being released from prison,inmates who had taken such courses committed far fewer crimes overall than other inmates.
Which of the following is an assumption on which the argument depends?
A.Not being able to take college-level courses while in prison is unlikely to deter anyone from a crime that he or she might otherwise have committed.
B.Former inmates are no more likely to commit crimes than are members of the general population.
C.The group of inmates who chose to take college-level courses were not already less likely than other inmates to commit crimes after being released.
D.Taking high school level courses in prison has less effect on an inmate's subsequent behavior than taking college-level courses does.
E.The governor's ultimate goal actually is to gain popularity by convincing people that something effective is being done about crime.
