The middle of the plot diagram typically includes key events that develop the story's conflict and lead toward the climax. In this context, the two correct answers that would fit this part of the plot diagram are:
- After listening to his story, Gortsby accuses the young man of lying because he cannot produce the cake of soap that forms part of his story.
- After the young man leaves, Gortsby finds a cake of soap lying on the bench and believes that the young man left it there.
These events contribute to the development of the plot and lead to the climax, as they involve Gortsby's changing perception of the young man and the discovery that could alter the course of the narrative.
