The four wrong answers will be mentioned as support for the biologist’s hypothesis. The correct answer will not be mentioned as support for that hypothesis, because this is an EXCEPT question.
Stated. This provides support by establishing that there is indeed an extinct environmental condition to which the pronghorn might have adapted. If we can’t show that there are extinct predators of the pronghorn, then that would undermine the hypothesis.
