Indirect questions are more polite and more formal than the direct questions.
They come after introductory phrases combined with interrogative pronouns and adjectives (who, whom, what, which, whose), adverbs (when, where, how, why) or if, whether.
We can use many introductory phrases such as I ask, I wonder, I want/would like to know, I can't remember, I have no idea, I am sure etc., or they can be introduced by expressions such as Can you tell me, Do you know, Do you remember, Have you any idea.
