French language Q&A Forum

One line has an answer of “C'est l'un des plus anciens lieux de culte du pays.”

and then also of “C'est un des plus anciens lieux de culte du pays.”

But the audio is “c’est l’un”, not “c’est un”, so I guess the second answer shouldn’t appear as an option, even if it’s a grammatically correct alternative. 

Not a big issue, but I thought I’d mention it.

"It is green" still gets "il est vert" marked wrong, despite the fact that it appears to refer to a specific item (as opposed to using "c'est vert," the preferred answer, which would indicate something more general--despite no indication of such in the sentence). Tired of having my score set back (I had to use up most of my free quizzes for the month to make up for this). Please fix. Would also be nice to have the "report it" button on the page that people seem to say exists but which I have never seen.

I was wondering would these two sentences I made up be correct? I'm trying to understand the difference between the 12hr and 24hr.

Je me couche à vingt-deux heures 

I go to bed at 10pm

Je me révielle à neuf heures 

I wake up at 9am

Thanks
