I would like to particularly congratulate the person who gave us this piece.  Not only was it enlightening for me, but it was also a perfect B2 listening exercise. Thank you.  Now to my question.  I understand the admonition about the use of present tense to relate a historical story.  How does the use of the future perfect in the first paragraph relate to this?  Were there other choices for this tense?

"...vous pourrez programmer votre combinaison personnelle quand vous arriverez ici." (recommended answer)

"...vous pourrez programmer votre combinaison personnelle quand vous serez arrivés ici." (marked incorrect)

While I do realize that the construction is covered at a higher level than this writing exercise, I was curious if the second sentence is grammatically or situationally incorrect? Or maybe just not preferred?

Merci!

Hello, please advise if ´bien entendu’ is an adverb in the phrase J'avais bien entendu parler de ce nouveau poste and parler should be a participle 

Thank you 

Bonjour …. Pls explain when to use échapper and when to use s’échapper ?

Why can't I use "relâcher" here? As that verb means to relax a muscle? 

Why "au praliné" and not "au praline"?

In the song Jalousie by Angele, in saying the English question, "Who is that girl in the photo", why does she say,

"C'est qui cette fille sur la photo" rather than "Qui est cette fille sur la photo"?  

Is this Walloon French, since she is from Belgium?  Thank you very much.  

Is it because fatiquer is transitive ‘only’ and ‘must’ have an object, otherwise fatiguée here is an adjective?      Might be back to A level for me!

Why is ‘ne soyez’ marked correct.  Isn’t this subjonctif passé and isn’t fatiguer conjugated with avoir in compound tensed?
