Final answer:
McMurphy is not mentioned in the given text; instead, McTeague is the central character who experiences agitation and bewilderment due to the breaking of his pipe and troubles with his friend Marcus and a woman named Trina.
Step-by-step explanation:
It appears that the student is asking about a character named McMurphy and his reactions to the actions or inactions of other characters, potentially from a literary work. However, the provided excerpts do not mention a character named McMurphy, but instead focus on a character named McTeague.
In the excerpts, McTeague becomes upset for various reasons, such as the breaking of his pipe, misunderstandings with his friend Marcus, and the daunting prospect of calling on a woman named Trina. The breaking of his pipe, which he could understand and respond to directly, rouses him to action.
McTeague's experiences cause him a range of emotions, from agitation to bewilderment, and illustrate his simpler ways of dealing with problems in contrast to the complexities of personal relationships and perceived injustices.
