【答案解析】The 1950 McLaurin decision was one of the decisions that provided legal precedents for the 1954 Brown decision. Choice A is incorrect. McLaurin preceded Brown I. Therefore, it could not have superseded a decision that had yet to be made.
Choice B is incorrect. Brown I followed McLaurin. Therefore, it could not have set a precedent for McLaurin.
Choice C is incorrect. Brown I reversed Plessy v. Ferguson. It built on McLaurin.
Choice D is incorrect. McLaurin preceded Brown I. Therefore, it could not have limited the application of a decision that had yet to be made.
