why is c correct

Thanks for your question @marissa Answer choice C states "Passage B displays an awareness of the arguments touched on in passage A, but not vice verse." The entire first paragraph in passage B is a direct reference the arguments made in passage A. Passage A does not contain any such references to the arguments in passage B. Answer choice B states that "Passage B advocates for a policy that Passage A rejects." This is incorrect because the truth is the other way around: Passage A proposes a policy that passage B rejects. Passage B does not actually propose any policies; it simply argues against the policy advocated for in passage A.
