French language Q&A Forum

Can I please ask for a little explanation on why is there Conditionel Passé in the text: "elle aurait été" and further on. Thank you!

Could you help me find a reference to understanding the use of prepositions before infinitives (I understand prepositions after).

Also, I read the question as 'after months of wearing', but can à be used for the preposition 'of'?

Why not faire...

Good day
Please see the question below:
La France est dotée d'un territoire aux climats et aux reliefs variés, grâce ________ sa production agricole est très diversifiée.

I wrote "à qui", but it was marked incorrect, saying that "auquel" is the only correct answer. Why is "à qui" unacceptable in this context?

peut-on utilise ménage dans la phrase "Avez-vous demandé au reste de votre maisonnée "  ?

merci

I translated ancient crater as  "cratère ancien", but the answer guide has "ancien cratère". The lesson about "ancien" says that it means "ancient" after the noun, but "former" before. Why is it before the noun here?

I answered the question "Elle a manqué le bus, donc elle doit ________." as aller a pied, but this was scored as incorrect. But the lesson tells me to use this when walking is CONTRASTED WITH ANOTHER MEANS OF TRANSPORT, which it seems to me is exactly the case here! 

What am I missing????
