参考答案
正确答案：A
解析：Because the formal operational stage is the last stage in Piaget's theory, and the age range is between 11 and 15, it must be concluded that people who are older than 15 have completed all of the stages. Choice B is not correct because the age range for the formal operational stage is between 11 and 15. Choice C is not correct because logical reasoning replaces intuitive thought in the concrete operational stage from 7 to 11 years of age. Choice D is not correct because there is no evidence to support this conclusion in the passage.
