I like having fun with these folks... 9000$ govt grant, never needs to be paid back...all that jazz. It's a scam. Similar version ran in '13 and earlier.
If you want to have a little fun, go ahead and answer. Lead them on and get as much info from them without giving out yours. Get creative but don't let them know you're onto them until you're done with them. I'm curious if they'll call me and try to pull the same stunt later.
