can I know how to generate follow up dialog follow up 1 topic?

[trangtv57]

greate job,
Tks you so much for sharing, I have a question about prompt engineering that You make a dialog around 1 topic like you say:
"We sample 200k specific questions and 250k general questions along with the 50k meta-questions, and we generate a 3~7-round dialogue for each.".
I can understand how to generate first turn, but how to prompt to gpt-3.5 or gpt-4 generate question to ask improve quality of passage, or detail information about 1 topic. Can give me detail. I can't find more info about this in your paper.
Tks
