Final answer:
The middle of a narrative, which is where conflicts arise and tension builds leading to the climax, is known as the rising action.
Step-by-step explanation:
The new problem or middle of a narrative is called the rising action. This part of the story includes a developed series of events that produces increasing tension, engages readers, and leads up to the climax of the story. The rising action introduces secondary conflicts and creates tension, making the climactic moment possible, where a significant action or turning point occurs.
