Final answer:
The term for the highest point of interest or intensity in a story is the climax, which is the moment the main conflict peaks and leads to its resolution.
Step-by-step explanation:
The term for the point of greatest interest or highest intensity in a story is climax. The climax is often referred to as the turning point or the peak of action in the narrative. It is during this pivotal moment that the main conflict reaches its most intense point, compelling the characters to take action which leads toward resolving the conflict. The climax can manifest through various forms such as a character's epiphany, a showdown between protagonist and antagonist, or the culmination of an internal struggle.
Understanding the climax is essential to grasp the structure of a story, which typically includes the exposition, rising action, climax, falling action, and finally the resolution. The rising action builds up tension and develops the conflict leading to the emotional high point, the climax, followed by the falling action and resolution, where the storyline concludes and the conflict is resolved.
