Final answer:
Raymond Carver's protagonist in 'Cathedral' evolves from being closed-minded to open-minded, facilitated by his developing connection with Robert, the blind man.
He begins as a passive character but undergoes significant emotional growth, making him the primary focus and hero of the story.
Step-by-step explanation:
The protagonist in Raymond Carver's Cathedral is a complex character who undergoes significant personal growth throughout the story. Initially, the protagonist appears closed-minded and prejudiced, particularly with his discomfort about Robert, the blind man visiting his home.
However, as the story progresses, it becomes clear that he is capable of change. The interaction and connection with Robert prompt an epiphany for the protagonist, leading him to shed his prejudicial views and open his mind to a new perspective on life.
This transformation culminates in the drawing of the cathedral, where the protagonist's character truly evolves, showing how a seemingly passive observer can become emotionally engaged and transformed by experiences.
Revisiting the question, the answer would be a) The protagonist is open-minded and willing to change, as seen when he connects with Robert. This is demonstrated through his initial skepticism and later genuine engagement with Robert, leading to an unexpected kinship that symbolizes his internal change.
The protagonist starts as a figure of isolation, akin to the solitary figures mentioned in the description of cathedral portals, but like those figures, he also undergoes a change across the story's narrative arc.
