I’m not familiar with the rule of ‘re’ bring added to ‘grossir’ in order to say someone is doing something again.  Is this a general rule?

La jupe de claire, c'est ......

A- chère

B- cher

In the 2nd quiz on plus-que-parfait (La soiree de mes Reves), the 4th blank from the END requires us to conjugate faciliter in the plus-que-parfait tense. 

According to me, it should be : ce qui nous avions facilite (with an accent on the last e of facilite); however the solutions key is showing it to be nous avait facilite (with an accent on the last e of facilite). 

Can you please explain why we are using the 3rd person singular form of conjugation of the auxiliary verb in imparfait (il /elle / on avait) rather than that with nous (avions) here ?

It's not clear to me when used on. I'd appreciate some guidance about the use of that pronoun.

Hello,

Would you be able to use the 'on' form of the verb in a sentence such as 'my family and I watch a film - ma famille et moi regarde un film' or would it need to be the nous form - ma famille et moi regardons un film?

The lesson didn't mention much about "par".
Is it really used just for those few mentioned in the note?

Why not "etait ajoutee"
