population problem

by mehaksal » Wed Aug 15, 2012 5:58 am
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.

OA says D...what about B??

Option B is wrong because it is not supported by the statement. Wolves can double their numbers every year. They do not do so, however, if the area in which they live is already full means that the wolves won't double their number unless there is room for everybody. The lone wolves are the ones unable to establish a territory and not the ones resulted from the doubling of the pack.
I have a doubt between D and E.

IMO D


A) Against the para as wolves control their population increase
B) We do not know whether at what point the wolves are ajected at double or at quadruple.
C) No such info provided in the paragraph.
D) correct answer
E) the wolves control their population increase but does not mean that their total population numbers remain the same.
