French language Q&A Forum

I put in some different answers from what was accepted and wondered if any of the following were possible. 

1. For "I really need to save", is it OK to use "il faut vraiment", or does "absolument" always naturally go with "il faut" ?

2. For "I've stopped buying expensive brands", can I also use the reflexive "Je me suis arrêtée d'acheter des marques chères" ?

3. For "and instead I've tried the supermarket brands" can we use "au lieu" in place of "à la place"?; and finally :

4. For "I must admit", can the verb "avouer" replace "admettre", as in "Je dois l'avouer..." or does this have a different sense ?

Thanks

Why is "j'ai regardé dans le frigo" not accepted ? 

So while you can’t say ‘J’ai des autres chaussures’ , can you say ‘j’ai besoin des autres chaussures?’  More important, how would you say ‘I have some of the other shoes?’ How is that not ‘des autres chaussures’? 

Initially I was a bit confused,

Very interested by Chris’s use of “depuis” in “Je regarde depuis de belles collines”. Does using “depuis” impact a slight change in the English translation such as “I have been watching from beautiful hills” or am I overthinking it.

Avant d’obtenir une réponse: is ‘avant de recevoir une réponse also OK?

As a native English speaker, interrogations makes no sense in this context.  The suggested vocabulary noted "existential questions" but it never appeared.  Instead, we got interrogations.   Seems like an oversight.

How would you say "someone hadn't lived there since [insert year]"

Depuis que j’ai 4 ans ,,,,où. Dès que j’ai 4 ans???
