Passage Summary: A park tried to use wolves to stop moose from overpopulating and eating all the plants, but even though the wolves were healthy and eating, the moose population kept getting bigger.

Reasoning: Wolves were introduced to control the moose population and they thrived, yet the moose population increased anyway.

Analysis: We are faced with a paradox: the predator population is doing great, which implies they are eating the moose, yet the moose population is still expanding. To resolve this, we need a piece of information that explains how the moose could thrive despite the wolves. Perhaps the moose had an even better year for food than the wolves did, or maybe the wolves were eating something else entirely. Look for an answer that provides a reason for the moose population's resilience or a factor that limited the wolves' impact on the total moose count.
