Final answer:
Starting with narration before moving into dialogue in a fiction piece can provide a clearer picture of the narrator's intentions and background information, creating tension and establishing the setting. Option number C is correct.
Step-by-step explanation:
Starting with narration before moving into dialogue in a fiction piece can have several effects. One effect is that it gives the reader a clearer picture of the narrator's true intentions with their conversation with the other character. It allows the reader to understand the narrator's motives or ulterior motives, which can create tension and suspense in the story. Another effect is that it provides exposition and background information about the characters and the conflict before the dialogue begins, giving the reader a better understanding of the story.
It can also help establish the setting and atmosphere of the story before the characters start speaking. Therefore, option C, 'It gives the reader a clearer picture of what the narrator's true intentions are with his conversation with Fortunato.' best describes the effect of starting with narration before moving into dialogue.
