Do you know? // where does she live?

Can you tell me? // Where is the post office? 

Could you tell me? // When does the post office open?

Can you say? // How do you make a cake? 

would you tell me? // How do I use a computer?

Could you describe in this map? // How do i get to the bank? 

Do you know? // where do you meet your brother?

Would you mind telling me? // Where does she work?

Do you have any idea? //Is she at home today?

Can you remember? // When is the concert?
