Reversing. swapping the verb and subject and adding a hyphen
e.g. es-tu ...?
just raising your voice/ adding a question mark
e.g tu es....?
and I can't remember the other one, sorryyyy. I'll check my book, wait a sec
Elle a visité Paris et Rouen.

I don't know if I properly undeerstood the second part of the exercise but the "de" corresponds to the "d' " in the question.
The answer is 1608
thx if right
