Hi there! Wondering if you could explain why sometimes "have been + verb" is in the present and sometimes the passé?
E.g. "... l"alsace est multilingue..." (Alsace has been multilingual...) vs. "l'Alsace a gardé son multilinguisme" (Alsace has kept it's multilingualism)
Merci d'avance!
L'alsace est plurilinguique depuis des siècles. -- The Alsace has been multilingual for centuries.
There's a dedicated lesson to using depuis with present tense and not passé composé: Using the present tense (Le Présent) - and not the compound past (Le Passé Composé) - in sentences with "depuis" (since/for) in French (French Prepositions of Time)
The second sentence you quote is just standard passé composé.
