I just get asked those two questions a lot - pretty much every single survey - and I often get kicked out right as I answer either one of those questions. I think the surveys look for diversity, or maybe Hispanic ethnicities are underrepresented in the results so after awhile they've met their quota for other people, but are still looking for Hispanic ethnicities. I've successfully completed plenty of surveys, but one of the times I also seem to get kicked out is when I answer that I don't have any children. It makes sense to me - I'm perfectly capable of reviewing ads or alcoholic beverages, but not diapers or things related to having a big family, whereas someone with kids is perfectly capable of reviewing all of those things so might qualify more often.
