Final answer:
Unified Resolution is the term that characterizes a structure in Paradigm 2 as closed or resolved, indicating no need to continue on.
Step-by-step explanation:
The term that characterizes a structure in Paradigm 2 as CLOSED or resolved, with satisfaction both at the end of the second phrase and the end of the fourth phrase, indicating no need to continue on, is Unified Resolution. Unity and satisfaction are achieved in this type of structure, bringing closure to the piece of music or literary work. This can be compared to the resolution or dénouement in a story, where all loose ends are tied up and the central conflict is resolved, leading to a sense of completion.
