Answer:
Passage 1 describes behavior that erroneously appears to be friendship; Passage 2 analyzes two different approaches to friendship.
Step-by-step explanation:
Without knowledge of what level of English this is (I'm sure it was there, I just didn't see it) or what information the passages had, I took apart the question and applied the individual key parts of it (what sounded best, describes friendship, how the topic is being treated, the two passages must be different, and how likely it seemed to be the answer) to narrow down the answers.
The answer can't be "Passage 1 alms to warn the reader about a certain type of friend; Passage 2 tries to caution the reader" because the question was "what best describes how the topic of friendship is treated differently in Passage 1 and Passage 2?" and the the answer here would suggest that both passages 1 and 2 treat the topic of friendship the same, to warn/caution the reader.
The answer isn't "Passage 1 tells a story about a fictional friend; Passage 2 presents Information about an actual friendship." This answer seems like it could be right, however, it is talking about friends not friendship which is the topic. Though Passage 2 does mention friendship, Passage 1 does not and instead mentions fictional friends, not friendship. Unless the passages themselves spoke about the differences between fictional and real friends and friendship this answer is incorrect.
The answer could be "Passage 1 describes behavior that erroneously appears to be friendship; Passage 2 analyzes two different approaches to friendship." This answer uses larger words that people may be unfamiliar with, and that makes it seem smarter (these words could be vocab though) and it makes a lot of sense when put in context with the question, however, Passage 1 talks about describing the behavior that appears to be friendship while Passage 2 talks about the two different approaches to friendship. Yes, we want the two passages to have different answers, but we want the answers to make sense when applied to the question and each other along with whatever the passages say. The approach towards friendship is vastly different then the behavior in a friendship that is not real (erroneously means mistaken). This answer would make sense.
The answer might be "Passage 1 describes a friend in a serious way; Passage 2 describes friendship with humorous words and phrases." Simple and makes sense when put in context with the question. both passages describe friendship differently and can be applied in a variety of different situations. This is the safe choice.
