Neurobiologist Sapolsky from Stanford University used a blowgun to tranquilize baboons in the Kenyan savanna. Once immobile, he could attach radio collars and track the baboon's movement. In one study, whenever a baboon's radio collar slipped off he would put it back on. This would involve another session of immobilizing the baboon with a tranquilizing dart. He noticed that female baboons that were frequently recollared had significantly lower fertility rates than uncollared females. Probably, therefore, some substance in the tranquilizer inhibited fertility.

Which of the following is an assumption on which the argument depends?

(A) The dose of tranquilizer delivered by a tranquilizer dart was large enough to give the Sapolsky a generous margin of safety.

(B) The fertility rate of uncollared female baboons had been increasing in the past few decades.

(C) Any stress that female baboons might have suffered as a result of being immobilized and handled had little or no negative effect on their fertility.

(D) The male baboons did not lose their collars as often as the female baboons did.

(E) The tranquilizer used in immobilizing baboons was the same as the tranquilizer used in working with other large mammals.

Hello there,

Can I have your thoughts on this please - 3-4 of the answers, seemed reasonable for me. I chose correct OC in the end, but couldn't quite say why it was correct.

Many thanks.


Conclusion : Tranqued and collared baboons less fertile. So tranqs must be affecting baboon.

a) Completely out of scope.

b) We are only concerned about the monkeys that have been collared. Out of scope.

c) Correct answer. This assumption eliminates any alternate cause for the reduced fertility in the female baboons. This option also passes the LEN test.
Any stress that female baboons might have suffered as a result of being immobilized and handled had some negative effect on their fertility. Hence conclusion is killed.

d)Totally out of scope.

e)Totally out of scope.


Kudos Please... If my post helped.

Good ques..ans C

Some substance effected fertility. Cause - > Effect.

Assumption : Nothing else might have had effect on fertility --> Other causes dont have intended effect.

The assumption should be - none other than tranquilizer can be the reason for low fertility.

SO the crux of the argument was that the recollared baboons fertility was getting infected by the tranquilizer

Concluding that some substance in the tranquilizer inhibited fertility.

The author was assuming C
(C) Any stress that female baboons might have suffered as a result of being immobilized and handled had little or no negative effect on their fertility.

When negated will weaken the conclusion.
