Critical Reasoning (CR) | Re: Boreal owls range over a much larger area than do other owls

Solution: The small mammals on which owls prey are relatively scarce in the forests where boreal owls live. That is why boreal owls range more extensively than do other, similarly sized owls in search of food.

B confirms the statement - It indicates that abundance of food for the boreal owls' small-animal prey in an area correlates with a smaller range for the boreal owls there.
