If the verb is se passer, should it not be "Comment tes vacances se sont-ils passées" 

If the verb is simply passer, should it not be "Comment sont passées tes vacances"

I know that ils is used for masculine or mixed masculine and feminine groups and elles is used for feminine groups. But what if there are more feminine than masculine objects such as a group of one man and ten women? Would it then be acceptable to use 'elles' to refer to that group or would I still have to use ils even if only thing is masculine?

It was in another new year exercise but not this one. Why not?

Bonjour, why is it not 'nous sommes arrivées'? I put an extra 'e' because Marie is a female.

On the 4th or 5th question, in the english phrase they wish us to translate, at the end of the phrase, there is a point ("."). But when i put the point in my french phrase, it was marked as wrong, causing me to lose points, I assume. 

Please fix this error or explain it to me!

Thanks,

Karina

It says jusqu'à ce que and subjunctive is for until someone does something so for example 'we kissed until his parents arrived'. But could it also apply to 'we talked until it became too late'? So a second part of the sentence not done by someone but a situation without a person and action.
