Je sors de Narbonne en ce moment-même.

Question

Never sure about this one. I use ‘sortir’ when I’m leaving a house, for instance, but how does one ‘go out of’ a town? Seems to me that the examples using ‘partir’ and ‘quitter’ are the only correct ones, depending on context.

Accepted Answer

Bonjour Richard,
Chris is correct: there is a specific note on "sortir de + [city]" in this lesson. It is sued when you are describing the action in progress (as you speak for example). 
Je quittte / pars de / sors de Lille en ce moment-même. = I am leaving Lille as we speak.
See here: Expressing "to leave" with partir/laisser/quitter/sortir in French
I hope this is helpful.
Bonne journée !

Answer

The lesson clearly specifies the circumstances under which one can use sortir de + city. Which examples do you think are incorrect?
