Final answer:
The answer supported by the details in the excerpts is that Rena expresses both class and race prejudices, as she reflects on her complex feelings and societal attitudes towards her identity.
Step-by-step explanation:
The statement supported by the details provided in the excerpts is that Rena expresses both class and race prejudices. This is evident in the excerpt where she grapples with her identity and the conflicted feelings that arise from the interplay of race and class dynamics. Her introspection on hate coupled with desire reflecting the broader societal attitudes captures the essence of her prejudice and complexity in understanding racial relations. Moreover, the references to historical figures and critiques in the context of class and race further confirm the presence of these prejudices. The excerpts do not provide explicit evidence supporting Maurice's expression of class and race prejudices, or that Maurice or John Warwick exhibit deep-rooted resentment.
