hey everyone, i came across this today with a student of mine. we were doing an exercise where you had to say whether each sentence was active or passive ( 'This house was built by Tom' or ' My mom cleaned my room'., for example).

Usually I have no problems with the passive but I got stuck on this one and am hoping someone can bear the boredom of explaining it to me!!!!

Where has he been?...........passive or active?

Thanks for the help!
