Explanation
A. Passage B mentions the norm that a chef must not copy another chef’s recipe innovation exactly, implying that there is a social norm against copying, even if using as inspiration.
B. (Correct Response) The passage states that social norms function similarly to legal protections and that violating these norms can lead to sanctions from peers, such as being denied information.
C. While this statement is true, it is not the focus of Passage B, which discusses the function of social norms rather than copyright law.
D. The size of the community is not discussed as a factor in the effectiveness of enforcing social norms in Passage B.
E. Passage B does not delve into the practical difficulties of determining whether a recipe has been copied exactly; it focuses on the norms that govern chefs' behavior regarding recipe sharing.
Passage B supports the idea that chefs adhere to a system of social norms that includes punitive measures against those who violate these norms, such as withholding information, which aligns with the statement in option B.
