正确答案:A
题目详解
反馈
Choice A is the best answer. In lines 38-39("The...scanners"), the passage describes part of Maguire's study by stating that "the researchers put both the mental athletes and a group of matched control subjects into MRI scanners." In the context of a study that has two groups of subjects, the word "matched" suggests subjects that are similar or comparable. 
Choices B, C, and D are incorrect because in the context of a study with two groups of subjects, the word "matched" suggests subjects that are similar or comparable, not ones that are exactly the same (choice B), ones that are recognizably different (choice C), or ones that are rivals (choice D).
