Hi rewboss,

Thank you for your reply. Interrogative pronouns are sometimes killers for English learners. I agree with you basically, and Michael's explanation would complement the point.

To all (if you have a chance to see this thread again),

Let me confirm one thing. I first got confused with the sentences in question because I'd been thinking of "My last meal would be XXX" and then encountered "What would be your last meal?" as its interrogative. Why the complement can be shifted to the subject position?

There may be a rule, such as when the sentence is "S + 'be' + C," and when you want to replace C with an interrogative to make a question, C can be switched to S and S to C.

I am Ricky.
Who are Ricky?
Who are you?

Julia is a student?
What is Julia?
Who is a student?
