Question

how does the frame-story structure create tension? done

Explanation:

A frame - story structure (a story within a story) creates tension in several ways. First, there can be a contrast between the frame narrative and the embedded story. For example, the narrator of the frame might have a different perspective or agenda than the characters in the embedded story, which creates uncertainty about how the two will interact or how the embedded story will be interpreted. Second, there is often a mystery or question surrounding the frame narrative itself, such as why the narrator is telling this story or what their relationship is to the events in the embedded story. This unanswered question keeps the reader engaged and tense as they seek to understand the full context. Third, the frame can create a sense of confinement or limitation for the embedded story, making the reader wonder how the characters in the embedded story will break free from the constraints imposed by the frame or how the frame will ultimately resolve in relation to the embedded story.

Answer:

A frame - story structure creates tension through contrast between frame and embedded story perspectives, mystery about the frame narrative's context, and a sense of confinement/limitation for the embedded story.
