Create file, prompts for fine tuning

I would like to create a chatbot for education.
The bot will help the students in QnA format.
The answers are based a specific book, a learning material.

I selected prompts and completions from the book and created a
{“prompt”: “”, “completion”: " <ideal generated text|>"} JSONL file.

Which type of prompt should I use in the fine tune JSONL file?
{“prompt”:“What are Earthquake Safety Tips? ->”,“completion”:" The safest place is an interior room.“}
OR
{“prompt”:“Q: Is the road safe? A: The road is not safe. Q: What is the safest place? A: ->”,“completion”:” The safest place is an interior room.“}
OR
{“prompt”:“This is a conversation between the teacher (Agent) and a child about the childfen safety.\n\nQ: Is the road safe?\nA: The road is not safe.\n\nQ: What is the safest place?\nA: ->”,“completion”:” The safest place is an interior room."}

Thank You very much Tamas
