Final answer:
The provided information does not match the question about Lena and Campbell's argument; therefore, it is not possible to give a detailed answer. The student is encouraged to refer to the text that includes these characters for context and analysis of their disagreement.
Step-by-step explanation:
The question seems to pertain to a narrative situation where two characters, Lena and Campbell, are having an argument, potentially about their perceptions of each other and their surroundings, as they near the end of First Avenue in the Tillman Park neighborhood. However, the provided reference material does not match the characters or situation described in the question. The information given is about a variety of literary works and themes, none of which appear to involve the characters Lena and Campbell, or the specific scenario of an argument between them.
Without the context of the correct literary work, it is impossible to provide a factual and detailed analysis of Lena and Campbell's argument, what started it, or the assumptions and perceptions they have about each other. It seems there may have been a mix-up in the provided material, which does not correspond to the student's question.
If Lena and Campbell are characters from a specific book or story not provided here, I would recommend the student refer back to the relevant text to examine the dialogue and interactions between the two for a clearer understanding of their relationship dynamics and the roots of their disagreement.
