Explanation:
We use reported or indirect speech to express the content of someone's statements, questions, etc.
When we want to transmit someone's question, we use one of the following options:
1. Yes / No questions
If we have this type of question, we transmit them into reported speech by using the following structure:
<u> verb (e.g. ask) + if/whether + clause.
</u>
e.g. The boss asked his secretary if she had typed those documents.
2. Questions with question words
If we use this type of questions, we transmit them into reported speech by using the following structure:
<u>verb (e.g.ask) + question word (where, when, why, what, how) + clause.
</u>
e.g. Colin asked who was at the party.
