Explanation
A. Neither Borges nor the author of Passage B suggest that genre is fully determined by the author's intention. Borges speaks of the reader's role in defining genre experience, and Passage B emphasizes the complexity of genre categorization.
B. (Correct Response) Borges in Passage A discusses how a reader could interpret any narrative as a detective story, which aligns with the statement that any science fiction story could be read as if it were a detective story.
C. Both passages suggest that genre classification is not always clear-cut, and there are "borderline cases" (Passage B) that defy unambiguous classification.
D. This option is not directly addressed in either passage. While Passage B discusses reading protocols, it does not specifically mention rhetorical figures unique to poetry or prose.
E. Neither passage suggests that enjoyment of a story is contingent on knowing its genre. Passage A, in particular, suggests that the reader's experience transcends genre categorization.
