NYU Noncustodial Parent Waiver Question

Two of the questions I’m confused on are “Have they remarried?” and “Have they had any other kids?” There isn’t an option for unknown like on the CSS waiver so should I check no or yes. I honestly don’t know what they’re doing with their life since I’ve never met them. Which option should I put?

Any help is appreciated.

If it’s an NYU specific form, do the most logical thing and contact the NYU financial aid office for assistance.
