In 1995, ecologists started to reintroduce the wolf into Yellowstone Park, where the wolf had been eliminated intentionally half a century earlier. Rangers expected a rise in the number of wolf would place limits on the elk population and on the populations of many mid-size mammals. One unexpected consequence was a dramatic rise in the population of foxes, which in turn helped to control many rodent populations.
Which of the following, if true, most helps explain the dramatic rise in the fox population?
(A) Foxes are too small to hunt elk
(B) Foxes choose very different breeding area than do wolves
(C) The main predators of the fox were coyotes, on which the wolf preys.
(D) Elk hunting is more popular, and more widely marketable, than is fox hunting
(E) In the agricultural counties surrounding Yellowstone, there are significantly lower wolf and fox populations.

W to eliminate E and other mid-sized mammals
F population rose and helped control many R
The irony is why F population increased?
(A) Foxes are too small to hunt elk
Doesn't justify why F population increased
(B) Foxes choose very different breeding area than do wolves
Doesn't justify why F population increased unexpectedly
(C) The main predators of the fox were coyotes, on which the wolf preys.
This makes sense. F --> C --> W, W ate the C, reducing the population and hence F got spared and hence, the population increased
(D) Elk hunting is more popular, and more widely marketable, than is fox hunting
Hunting is not a concern here, this is irrelevant
(E) In the agricultural counties surrounding Yellowstone, there are significantly lower wolf and fox populations.

Premise - Wolves were introduced in Yellowstone Park to limit the elk population and other mid-sized mammals.
Conclusion - unexpected consequence was noticed when there was a rise in fox population instead.
(A) Foxes are too small to hunt elk - Doesnt explain why the population of Foxes increased. Incorrect
(B) Foxes choose very different breeding area than do wolves - not explaining their population rise . Incorrect
(C) The main predators of the fox were coyotes, on which the wolf preys. this gives us a reason why the population of foxes could be affected by the introduction of the wolves in the Park. Correct
(D) Elk hunting is more popular, and more widely marketable, than is fox hunting. - even if it is the end goal was to limit the elk population either by hunting or by the introduction of wolves. this still doesnt explain why there was a rise in fox population. Incorrect
(E) In the agricultural counties surrounding Yellowstone, there are significantly lower wolf and fox populations. - doesnt give any extra information that explains the rise in fox population. Incorrect
