Explanation
A. While both passages touch on legal protections, they are not the primary concern; instead, the focus is on alternative systems to legal protections.
B. The passages do not focus on the connection between enforcement of social norms and the incentives provided. They do mention social norms but not directly in the context of incentives.
C. The balance between the rights of creators and the social value of making intellectual property publicly available is not the central topic of either passage.
D. Although practical considerations are mentioned, particularly in Passage A regarding the cost and uncertainty of lawsuits, this is not the primary focus of both passages.
E. (Correct Response) Both passages discuss how social norms function in place of formal legal protections within the communities of stand-up comedians and chefs. Passage A discusses how social norms provide protection against joke theft in lieu of formal copyright law, and Passage B illustrates how social norms among chefs mimic legal protections like patents and copyrights.
The main concern of both passages is exploring how social norms within certain professional communities can fulfill the role typically served by legal protections in safeguarding intellectual property.
