I've encountered this quiz: translate this sentence: "Marie worked for ten hours yesterday". The answer excludes this option: Marie a travaillé en dix heures hier.

Why can't I use the word "en"? It's mentioned here: En vs Dans with time (French Prepositions of Time)

"En expresses the length of time something takes to be done."

Je veux etudier des sujets autres que le passe simple, mais le programme me donne 9 questions du passe simple sur 10 dans chaque test, meme si j'active le test a partir des lecons sur d'autres sujets. Comment sortir de cet engrenage? 

Please update the question so that it includes the meaning of the individual words, I am on A0-A1 and it's near impossible to do these questions.

Hi, 

I was wondering why "je veux" is considered impolite in most contexts, but "voulez-vous" isn't, as they're both forms of "vouloir". Is it only impolite to use the verb "vouloir" when talking about yourself? So would, for example, "il veut" or "ils veulent" be polite?

Thanks in advance!

In the next to last sentence would it be more polite to ask "Je vous devrais combien?" instead of "je vous dois...."

Why does “started to cry” use mettre? “ mis a pleurer. Can’t make sense of it

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 ?
