Answer: True
Explanation: Dialogue is an important tool in storytelling, and it can be used in many ways to move the plot forward, develop characters, or create a particular mood or tone. However, when using dialogue as a narrative technique, it is essential that it serves a purpose to the plot. Dialogue that is irrelevant or extraneous to the story can detract from the narrative and slow down the pacing of the plot.
Good dialogue should reveal character traits, create tension, advance the story or plot, reveal important information, or illustrate character relationships. It should also be natural and realistic, and it should sound like something a real person would say in that situation. Therefore, any dialogue that is included in a narrative should be carefully crafted and serve a clear purpose in the story.
