"How many women live in France?"
Translation:Kiom da virinoj loĝas en Francio?
You probably haven't reached the "Home" skill where they have that explanation, so I'll copy paste it here:
loĝi - to live, to reside, to dwell (in a specific place)
vivi - to live, to be alive (the state of being)
In essence it's the same distinction as habitar/vivir (ES), habitar/viver (PT), habiter/vivre (FR), but I'm not sure if "vivi" can penetrate the realm of "loĝi" like it does in these languages - I think they're best kept separate.
