Choice B is the best answer because it presents the conclusion that most logically follows from the text’s discussion of the study by Versace and colleagues. The text indicates that newborn animals of some species are attracted to faces and to stimuli that resemble faces. These species, the text says, share two characteristics: they’re social and they practice parental care, meaning that parents care for their young. The text goes on to describe Versace and colleagues’ experiment, which showed that Testudo tortoises, which aren’t social and don’t practice parental care, were attracted to a stimulus that resembles a face. Since Versace and colleagues have shown that a species that isn’t social and doesn’t practice parental care nevertheless has the innate characteristic of being attracted to face-like stimuli, it follows that this characteristic shouldn’t be assumed to be an adaptation related to social interaction or parental care. 24 SAT PRACTICE TEST #9 ANSWER EXPLANATIONS SAT ANSWER EXPLANATIONS n READING AND WRITING: MODULE 2 Choice A is incorrect because the text indicates that the tortoise hatchlings, which are solitary and don’t practice parental care, were attracted to the face-like stimuli, not that they perceived the stimuli as threatening. Choice C is incorrect because the phenomenon discussed in the text is an attraction to faces and face-like stimuli on the part of newborn animals, which can’t show any learned characteristics since they were just born. Additionally, the text tells us that the tortoises Versace and colleagues studied aren’t social and don’t practice parental care, so any findings about those tortoises wouldn’t be relevant to the question of whether an attraction to faces in social species that practice parental care is innate or learned. Choice D is incorrect because the text gives no indication that adult tortoises were tested on face-like stimuli and, if adults were in fact tested, no information about how they responded is provided. Since no information about adult tortoises’ responses is provided, no conclusion comparing those responses to the responses of newly hatched tortoises can be supported.
