Why was this done?

So in school when I was 10, someone came in to speak to selected students in class just to ask some questions about our family and general stuff. We didn't know why this was, but out of a class of 30 there were about 5 of us selected.

She asked where my parents were from and things like that

What do you think it was about? We were never told. It was just to get to know us she asked about 6 questions or so.

Why was this done?
