Would it be wrong to say "il y rentre" instead of the corrected answer in the test " il y retourne"? 

This was a very interesting lesson to me that appeared in my dashboard but I have always believed that in daily life the subjonctif passé would not be used. Is this a question of educational level or are there simpler ways to express the same sentiments?

Do you use un or une when using nous and vous? I'm studying professions in sentences, and 2 of the sentences went as follows:

"Nous sommes ____ ____________" (The profession was a journalist)

"Vous etes ____ _____________" (The profession was a cook)

I'm confused on this and can't seem to find any articles online about it :(

for: This lady has an unquestionable elegance.

I used "elegance incontestable" and it didn't accept it

If talking about an electric car (fem) why wouldn't I say : c'est moins bruyantE? Correction says bruyant.

Use of prepositions with passer and repasser: (sorry can't get accents to work in this box!) I looked back at the B1 level avoir and etre with passer..... I'm not very sure about the use of a par devant etc. Which ones mean 'go past (again)' and which mean 'go in (again)'? I'm assuming the same prepositions can be used with both verbs.
