"Which ones are your children ?"
Translation:Lesquels sont vos enfants ?
In this case, does it matter whether you use "lesquels" or "lesquelles"? If not, what is the rationale for each case? (I put the latter and was marked correct).
Now I think about it, I'm inclined to think it should be "lesquels" because "enfant" is masculine. Is that correct?
Un enfant = a child (male) OR a child (female)
Une enfant = a child (female)
You could use "lesquelles" if the question were asked, for example, about children at an all-girls school, or some other circumstance if you were inquiring about a group of girls.
"Lesquels" refers to either all boys, or a group of boys and girls.
because the words position does not match the question, "vos enfants, lesquelles?" will be translated as "your children, which ones ?". You supposed to use "lesquels sont vos enfants ?" which translated as "which (ones) are your children ?" it's just the matter of the words position, really. Correct me if I'm wrong :)
"votre" is used for a single object. "vos" is used for multiple children/whatevers. Here's a list of all Possessive Adjectives: http://french.about.com/od/grammar/a/adjectives_possessive.htm
