Why not its?
Wrong forum, I'm afraid...
Seriously I mean to ask why can't this sentence mean "its presence" as opposed to "his presence"?
Again: wrong forum!
I've just now realized that this somehow landed in French, which is weird because I followed the link from the exercise in Italian. Very strange.
I would have spotted it earlier if you had mentioned why it's the wrong forum.
You are on the FRENCH forum!

Good, now you'll have to check that the language is the one you expect (top left hand corner of each page). good luck!
Sadly there's no indication in the Android app.
