Conservation officers justified their decision to remove a pack of ten coyotes from a small island by claiming that the coyotes, which preyed on wild cats and plover, were decimating the plover population and would soon wipe it out. After the coyotes were removed, however, the plover population plummeted dramatically, and within two years plover could no longer be found on the island.
Which one of the following would, if true, most help explain the phenomenon described above?
(A) Plover are ground-nesting birds, which makes them easy prey for coyotes.
(B) Wild cat and plover populations tend to fluctuate together.
(C) Coyotes are not susceptible to any of the diseases that commonly infect plover or wild cats.
(D) The wild cat population on the island was once significantly larger than it is currently.
(E) The coyotes preyed mainly on wild cats, and wild cats prey on plover.

The correct answer will explain why, after the coyotes were removed from the island, the plover population decreased.The fact that wild cat and plover populations tend to fluctuate together does not explain the decrease in the plover population. All it tells us is that there is a correlation of some sort between the size of wild cat populations and the size of plover populations.
