Final answer:
The given examples are all dialogue sentences using reported speech.
Step-by-step explanation:
These examples are all dialogue sentences using reported speech. When reporting statements or questions, we can use different reporting verbs like 'said', 'asked', 'told', etc. The reported speech is usually introduced by the conjunction 'that' (optional) or with a 'wh-' word like 'what', 'where', 'who', etc.
For example:
He said, 'May I come in, sir?'
Reported speech: He asked if he could come in.
