Passage Summary: We should move these bears to a new home because it's the only way they'll survive.

Conclusion: We ought to relocate some pygmy bears to a nearby island.

Reasoning: This move is the only way to save the species from extinction because their current home is being destroyed and no other suitable habitat exists.

Analysis: This argument moves from a set of facts about survival to a moral or policy recommendation. To justify this leap, we need a principle that connects the 'only viable chance' to the 'should' action. Look for a rule that essentially says: if a specific action is the only way to prevent a species from going extinct, that action must be taken. The strongest answer will bridge the gap between the biological necessity and the ethical obligation.
