I just have to invent some answers to prove I am no fool! Here it is:

I am dumb founded. You are definitely cleverer than me by figuring out the first 4 questions. I wonder what sort of "World History" is this. If you are not making it up just to fool me, then it is really a very strange assignment. A return riddle will be the appropriate solution for the fifth:

I have eyes but not see

I have ears but not hear

I have nose but not smell

I have mouth but not eat

If I look and see

If I listen and hear

If I breathe and smell

If I swallow and eat

The place to go is to come inside me

The way is no returning
