In order to say, "i prefer our houses to theirs" is it acceptable to say, "Je préfère nos maisons à les leurs ." ?

As an aside, I found it so easy to add accents in this new format. It is a super improvement indeed! 

i thought with body parts it was usually 'les' which should be used.  In the suggestions during the exercise, there were options to use either. Does it depend on the verbe (trempe or plongé) ?

My understanding of "être" in passé composé is that it's supposed to be used for reflexive verbs. If this were true, then "je suis allée" would imply, in the present tense "je me vais", which isn't correct. Could someone explain this?

How would we say "Every morning, she wakes her brother up to go to school" or "you woke me up this morning"?

I don't know if this is important, but in English (at least, American) we don't usually say "food shopping" but "grocery shopping". =)
