Final answer:
Geyan's story lacks coherence, which is one of the criteria for a good story identified by Walter Fisher. Without coherence, the plot and characters appear disorganized, leading to an ineffective narrative.
Step-by-step explanation:
According to Walter Fisher, a good story must meet two criteria: fidelity and coherence. Fidelity refers to the reliability or trustworthiness of the story, while coherence refers to how consistent and orderly the story is. Given that Geyan's story has many elements that seem out of place and a plot that is difficult to follow, it is lacking in coherence.
Coherence ensures that a story flows logically and that the plot and characters are developed in a way that is understandable and engaging to the audience. Without coherence, as in the case of Geyan's story, the audience may find it difficult to follow the narrative, resulting in an ineffective story.
