timama [110]

Answer:

rising action.

Explanation:

Rising action is a term used in literature to describe the corresponding portion of the story, that occurs immediately before the climax, by increasing its atmosphere or builds-up whereby the tension level surges.

Climax, on the other hand, is a form of the highest point major turning point in a story.

While falling action is the point where there is a quick decrease in tension level, and follows immediately after the climax

Resolution is also known as the final part of the story, it follows immediately after falling action.

Hence, when the problem within the story gets more intense and builds, this is the "Rising Action."

spayn [35]
