PrepTest 134

Incorrect. There's no discussion of habitat quality, so this answer is out of scope.

Incorrect. The stimulus sets out hitting 250 panthers as necessary to being self-sustaining, not sufficient for it.

Correct. Argument or Facts:
Facts

Question Type:
Must Be True

Stimulus Summary:
There are 70-100 Florida panthers alive, but they need to hit 250 to be sustainable, and more can't fit in their current habitat.

Answer Anticipation:
If no more panthers can fit in their current habitat, but there needs to be at least another 150 for them to be sustainable, then they're going to have to move to a bigger habitat if they want to have a shot at survival.

Answer Explanation:
This answer connects the various concepts from the stimulus. If the Florida panthers don't acquire a larger habitat, then they can't fit more than the 70-100 current panthers, thus limiting them below the self-sustaining population size.

Key Takeaway:
Look for concepts that overlap in Must Be True questions—they let you combine statements to form inferences.

Incorrect. This answer is way too strong—while their current habitat can't support more of the animal, they could always move.

Incorrect. The stimulus does note that the current population is much higher than it used to be, but it doesn't note that they used to live in a smaller habitat that limited their population. The current population is limited by the habitat, but the prior population may not have been limited by it (especially if it were the same habitat).
