Passage Summary: Cheetahs need a certain number of individuals to survive a disaster, but we realized that number is actually higher than we thought. Right now, there are just enough cheetahs to meet the old, incorrect number, and there isn't enough space for the population to grow any bigger.

Reasoning: Survival requires a population larger than previously thought, but the current population is at that old level and the habitat cannot support any more growth.

Analysis: To find the most strongly supported statement, we must synthesize the provided facts. If the survival threshold is higher than X, and the current population is exactly X, and the population cannot exceed X due to habitat constraints, then the current population is necessarily below the actual survival threshold. Look for an answer choice that points toward the cheetahs' vulnerability or the impossibility of the population reaching a safe size. You are essentially looking for the logical 'sum' of these biological constraints.
