Their population must Sustain → 250+ reach at least 250 if it is to be self-sustaining.
Their current habitat is Current not large enough to → ~250+ support any more [than Habitat 70-100] of these animals, however.
If the statements above are true, which one of the following must also be true?
Some part of the panthers'
This may support the statement that the current habitat is unable to sustain more panthers, but this does not follow from the given statements.

Why this is right
If we contrapose the first statement, Sustain ? support 250+ we get this ~support 250+ ? ~Sustain We're told that the current habitat can't support 250, so we can infer that the current habitat can't sustain the population. When we see "Unless", we can replace it with "If-not" (if it is not the case that). So this answer is saying, "If the panthers do not acquire a larger habitat, their population will not be self-sustaining." That's essentially the same as, "If the panthers are stuck with their current habitat (or a smaller one), their population will not be self-sustaining".

This would explain how the Florida panther population increased, but doesn’t follow from the statements in the stimulus.
