Answer:
The plot's climax affects the story because often the most exciting things happen in the climax.
Step-by-step explanation:
For example, let's say there's a story about a dragon and a boy. They have been traveling together to find the lost queen. The climax happens when they find a lost queen because that's where there's the most action happening. It also may be the pivoting point of the story, or an important event that will be mentioned or indirectly referred to later on.
