Passage Summary: Most of the world's remaining forests are broken ecosystems that can't survive on their own, so if we want to save the endangered animals living there, humans have to step in and help.

Reasoning: Most remaining forests are fragmented and cannot sustain themselves; these fragments are the final homes for endangered species and require human management to keep those species alive.

Analysis: Since this is a 'Most Strongly Supported' question, we need to find a statement that follows naturally from the combination of these facts. If these fragmented forests are the *only* places left for certain species, and these forests *require* intervention to maintain those species, then it follows that without such intervention, those species are likely to disappear. We aren't looking for a wild leap, just a sober synthesis of the provided information regarding the necessity of resource management.
