Bonjour Linda,

Thank you for your comment. It is true that ‘vous’ can refer to one person, in which case it is singular (but could also be referring to a woman) or to a group of people, in which case it is plural (and could refer to the feminine or masculine gender).

If it is a multichoice kwiz, only one correct answer is given (despite the possibility of others). However if it is a written answer that is expected, there are several answers accepted.

I hope this is helpful.

Bonne journée !
