Happy to help. You're asking why (B) is incorrect.
The question says, "It is most likely that the authors of the two passages would both agree with which one of the following statements?"
(B) says, "Cather’s works were not intended as novels, but rather as narratives."
Passage B's author would almost certainly agree with this statement. However, passage A's author does not mention critical approaches to Cather's work anywhere in passage A, so we have no idea what her opinion is. As a result, we only know what one of the authors would think about this statement, so we can't conclude they'd agree on it. We can get rid of this answer choice.
(E) says, "Cather used impressionistic narrative techniques to portray the psychology of her characters."
The key to seeing how both authors would agree about (E) is to recognize that both authors have one primary point of agreement between them. They both believe that Cather used an impressionistic technique in her writing. Both authors agree that Cather wrote about her characters in the same type of manner (using the impressionistic technique), and this is the only facet of Cather's work that is discussed by both passage A and B. In passage A, the author states that Cather employed her writing style let her characters' "inner blaze of glory shine through the simple recital" of their actions and behavior (lines 7-8). In passage B, the author states that Cather's impressionistic technique used in describing her characters helped to "articulate the essential and conflicting forces of desire at work throughout Cather's fiction" (lines 60-62). As a result, we know that both authors would agree that (E) is true, so (E) is the correct answer choice.
