Explanation
A. (Correct Response) Passage A discusses Jorge Luis Borges' specific view on detective novels creating a unique reader and then broadens the discussion to the nature of literature and the reader's role. This moves from Borges’ specific observations to general literary theory. Conversely, Passage B starts with a general discussion on the definition of genres and narrows down to the specific notion of reading protocols, illustrating how genres might be distinguished based on how texts are read rather than their content.
B. Passage A does not begin with a competing view; it immediately presents Borges's perspective. Passage B does not build up to a discussion; it immediately delves into the complexities of defining literary genres.
C. The passages do not center around responding to counterexamples but are instead an exposition of ideas related to literary theory and genre categorization.
D. The passages do not start with contradictions but rather present theories on how to understand and categorize literary genres.
E. The passages do not describe a thought experiment but rather discuss actual theories about reading and interpreting literature.
