Question ID:PT13 S2 Q12 Passage:Harris: Currently, hybrid animals are not protected by international endangered-species regulations. But new techniques in genetic research suggest that the red wolf, long thought to be an independent species, is a hybrid of the coyote and the gray wolf. Hence, since the red wolf clearly deserves protection, these regulations should be changed to admit the protection of hybrids. Vogel: Yet hybrids do not need protection. Since a breeding population that arises through hybridization descends from independent species, if any such population were to die out, it could easily be revived by interbreeding members of the species from which the hybrid is descended. Stem:Which one of the following is an assumption on which Vogel’s argument relies? Correct Answer Choice:DChoice A:The techniques currently being used to determine whether a population of animals is a hybrid of other species have proven to be reliable. Choice B:The international regulations that protect endangered species and subspecies are being enforced successfully. Choice C:The gray wolf has been successfully bred in captivity. Choice D:All hybrids are the descendants of species that are currently extant. Choice E:The coyote and the red wolf are not related genetically.
