I believe it’s character vs character because he’s talking to another character and there clearly conflict between the two of them
This is a math question, so I wouldn't recommend putting it as "English," but yes, it is composite because it can be divided by 5.
Ms Mallard's character is constructed through the detailed internal thoughts looking through the window. Her moment of epiphany, sudden revelation, helps her grasp a life of freedom and feel it. Some guilty might cross her mind, however, considering that the role women played in the time the story is set was not trascendent, it is such a great opportunity for a woman to be a widow and have a property.
I would say that the pair of lines from the passage that contains a change in intonation is the first one:
But all the time / I'se been a-climbin' on
Because it shows a change in the tone of a poem.
