I learned that "ma" changes to "mon" if the female noun starts with a vowel, for pronunciation.

But does this "mon" changes back to "ma" if there ist another adjective in between?

(maybe not very relevant to this topic, but by seeing the examples, it reminds me of this) 

Pouvez-vous dire simplement "consigne" en lieu de "consigne à bagages"?

Je ne comprends pas le jeu. Je "click" sur the M, par exemple, mais rien ne se passe. J'essaie de le faire glisser jusqu'à la boîte, mais encore, rien de se passes. Peux-tu m'aide? Merci

Les enfants auront suivi le guide.     ->    Le guide aura été  suivi par les enfants.                 

 But this answer was marked incorrect:

sera suivie par

aura été suivi par (wrong)

Aren't they the exact same construction?  So why use sera here?   The passive voice has been the hardest aspect for me to understand since it seems so arbitrary.  Help!                         

Why do you need to put "l" before on" in this question? 

Why can't the sentence read "Il est important q'on agisse de façon?"

I was marked wrong for soyez parti (singular). Couldn't the "vous" refer to a singular person where past participle would be parti without an s?   What am I not seeing here? 

If you are asking someone their nationality, it is obvious that you do not know the person. In which case, wouldn't the question be informal in any situation?
