Could be false. The stimulus gives us no information about the quality of the habitat; we only know about its size. It’s possible that the habitat is of excellent quality and would be the perfect place for the Florida panther population if only the area were larger!

Could be false. The stimulus tells us that it’s necessary for the Florida panther population to reach 250 in order for the population to be self-sustaining, but it doesn’t tell us that such population growth would be sufficient to ensure self-sustainment.

Must be true. In order for Florida panthers to be self-sustaining, their population must grow; in order for their population to grow, they must live in a larger habitat. Therefore, in order for Florida panthers to be self-sustaining, they must acquire a larger habitat!

Could be false. If the Florida panthers acquire a larger habitat, the stimulus gives us no reason to believe that their population couldn’t increase greatly!

Could be false. The stimulus gives us no reason to believe that the Florida panthers occupied a different habitat in the 1970s than they do today.
