Final answer:
The statement about summarizing the plot and noticing how the conflict builds belongs to the Rising Action phase of the plot structure. This is the section where the conflict is developed and tension increases, leading up to the climax of the story.
Step-by-step explanation:
When summarizing the plot and noting the key ideas about how the conflict builds, this statement fits within the structure of the narrative during the Rising Action. The Rising Action is where the key events take place, the conflict is introduced, escalated, and fully developed. Next, the rising action fully develops the conflict. This developed series of events, the longest part of the narrative, produces increasing tension that engages readers and prepares them for the upcoming climax.
The climax, as the turning point of the narrative, is where the story reaches its highest point of tension and conflict, as well as the moment when action must be taken. Following this peak in the story's tension, we move into the falling action and eventually reach the resolution, where any remaining issues are resolved and the story concludes.
