Which is a purpose of good dialogue?

• A. To summarize the plot
• B. To present the author's opinions directly
• C. To advance the story and develop characters
• D. To decorate with fancy words

Answer: (C)

The main thing being tested is how dialogue serves to move the plot and reveal character. Good dialogue isn’t just people talking for talk’s sake; it shows what characters want, how they relate to each other, and what’s at stake, and it nudges the story forward. When characters speak, you hear their goals, tensions, and personalities in their word choices, rhythms, and pauses. That helps readers understand who they are and what will happen next without needing a narrator to spell it out.

So why is this the best choice? Dialogue that advances the story and develops characters creates momentum. It pushes events toward new situations, reveals relationships and power dynamics, and exposes subtext—the things characters aren’t saying outright but are implying through tone and implication. This makes the scene feel real and engaging, and it deepens what readers learn about each character.

The other ideas aren’t as effective. Summarizing the plot usually comes through narration or exposition, not through a character’s spoken lines. Presenting the author’s opinions directly breaks immersion and can pull readers out of the characters’ world. Decorating with fancy words can be a feature of voice, but it isn’t the primary purpose of dialogue; if dialogue is too showy, it can distract from what the characters are doing and what’s at stake.
