C is out of scope. We have no information about human encroachment on the wolves' territory.

As the stem says
'what may be inferred'
I think then only possible choice is D.

We have no information about human encroachment on wolf territory. Therefore, although it may be true, it is not a valid inference. Given our lack of information, it is equally possible that humans have backed off and created more territory for the wolves.

Thank you, Good one. Took a while but finally could arrive at the answer!
Would you rate this as a 700+ question?

I debated between D and E for some time.
Then, I read D the nth time, and thought of it as a conclusion of the passage, it seemed to suggest that the author was saying that wolf hunting in the in the fringes can continue (as if approving of wolf hunting), while the passage tone never seemed to give such a hint.
And hence I ended up answering as E... Sad

I am still not convinced with D... though it seems the best possible choice here, but it is not a balanced conclusion.
Can someone please help with my dilemma here?

E is a 180. The stimulus tells us that reproduction rates vary according to population density. That means density must vary,

Thanks Tani.

But when a question asks for "conclusion", then shouldn't the same be derivable from the passage without extrapolation unlike option D?
Though I get that this is the closest option, but isn't there a level of ambiguity there in this choice? Or do I need to change my thought process towards these qsns???

This question asks what conclusion could be properly drawn. It is not looking for a conclusion that is already in the stimulus. That makes it an inference question and the task is, in fact, to extrapolate what MUST BE TRUE based on the stimulus.

Wolves can double their numbers every year. They do not do so, however, if the area in which they live is already full and the territory of each pack borders on the territory of other packs on all sides. Lone wolves, unable to establish a territory near their place of origin, disperse to a less desirable habitat and often are hunted by people.

Which of the following conclusions may be properly drawn from the information in the passage above?

A. The number of wolves in any area suitable for wolves may be predicted to quadruple in two years.
B. Wolves are ejected from the pack to wander singly as lone wolves when the number of wolves in the pack has doubled.
C. The amount of territory suitable for wolves has been diminishing in recent years as a result of human encroachment, with a resulting diminution in the wolf population.
D. Wolf hunting can continue at a moderate rate on the fringes of a good habitat for wolves without a decrease in the average yearly wolf population in that territory.
E. The wolf population density in a given area of wolf territory does not vary with the yearly rate of wolf reproduction.
Process of Elimination if answer is not evident:

A. What if the saturation point is reached after one 2 year cycle?
B. A given wolf population may double again before it ejects lone wolves.
C. Out of Scope: Who knows the impact of human encroachment? The argument doesn't even show the impact of hunting.
D. The answer for reasons mentioned by others already.
E. The argument does not say that density and rate are not linked.

Instructors and students, please correct me if I am wrong.

hi everyone

Option A: "The number of wolves in any area suitable for wolves may be predicted to quadruple in two years". The part where it says MAY BE PREDICTED doesn't refute the first premise so in my opinion it would be ok to conclude this. I just dont see why its wrong.

+1 for D

A is wrong. It goes against the latter sentences in the stimulus. A person maybe misguided into selecting A if he is in a hurry and pays attention only to the first line.

B is wrong. The passage does not supply information regarding whether wolves are ejected from the pack or they leave at will.

C is wrong. No information regarding human encroachment in stimulus.

D is correct.

E is too strong. All the passage says is that "Wolves can double their numbers every year". The stimulus does not supply any information regarding what the original population of wolves is. If there is scope for the population to grow and double within the area, then this WILL infact increase the population density.

Hope this helps.
