Final answer:
To determine Rufus's attitude towards black people based on his relationship with Nigel, one must analyze how Rufus treats Nigel: with prejudice, support, or indifference. The specifics of their interactions are key to identifying Rufus's attitudes.
Step-by-step explanation:
The relationship between Rufus and Nigel in the novel can shed light on Rufus's attitudes towards black people. Considering the context, if Rufus shows clearly negative, harmful, or unequal treatment specifically towards Nigel due to Nigel's race, it would suggest that Rufus is prejudiced. On the other hand, if Rufus's behavior towards Nigel is supportive, aiming to uplift or aid him without patronizing, then Rufus could be seen as supportive. However, if Rufus treats Nigel without any particular positive or negative bias, seemingly unaffected by Nigel's race, he might be described as indifferent. The actual answer would depend on the specific interactions and the broader social context presented within the story.
