How do we change Wh questions into indirect speech? Is it similar to Active & Passive voice?
When the interrogative sentence is not a WH question, we use if and whether. And, when we have WH questions, the reported speech remains the same as the question itself except the fact that the tense changes.
She asked me, 'Which book are you reading'?
This sentence changes to:
She asked me which book I was reading.
