Step 1: Identify the sentence type.
The direct speech has both an interrogative sentence and commands. In indirect speech:
- Interrogatives change to reported questions.
- Commands change to reported orders.
Step 2: Apply the rules.
- “Why have you disturbed me …?” → “why he had disturbed him …”.
- “Leave the room … and do not come here again” → “ordered him to leave the room … and not to come there again”.
Step 3: Conclusion.
The indirect speech is: {Father asked his son angrily why he had disturbed him in his sleep, and ordered him to leave the room at once and not to come there again.}
