Choice C is the best answer. According to the passage, Maguire found that taxi drivers' hippocampi are "7 percent larger than normal," which is evidence that "way-finding around London had physically altered the gross structure of their brains" (lines 10-14,"involved ...more"). In lines 20-26("neuroplasticity....true"), the passage indicates that this finding challenges an earlier consensus: "It had long been thought that the adult brain was incapable of spawning new neurons—that . . . the brain's basic anatomical structure was more or less static. Maguire's study suggested the old inherited wisdom was simply not true."
Choice A is incorrect because the passage does not indicate that Maguire used a new method in her study or that her findings demonstrate the validity of a method. Choice B is incorrect because lines 20-26("neuroplasticity....true") show that Maguire's findings disprove a popular viewpoint, not that they support one. Choice D is incorrect because although Maguire's findings call into question a previous idea, there is no indication that they challenge the authenticity of any previous data.
