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 ?

How do you know whether or not an adjective goes before or after the noun? 

Bonjour,

In this sentence which I found it in a book, vous etes combien dans ta famille?

Why they used "ta" and not "vos" or "votre"? 

Merci

These exercises are so helpful. Could please explain the usage of "en" in the phrase "Si j'en avais les moyens?" Why is not simply "Si j'avais les moyens?" 

Aujourd'hui je récolte beaucoup de citrouilles de me jardins.  Presque trente en tout.  Nous avons eu un peu de gel mais demains j'espère récolter le reste du maïs doux pour les geler.  Je suis en accord.  J'adore l'automne!!
