How do Facebook question pages get your data and what data do they get?

Lately, I’ve noticed a lot of FB notifications of friends asking stupid questions from other pages. The questions are usually along the lines of “What’s the first movie you saw in the cinema?”, “What’s the next number in this sequence?”, “What’s a food you hated as a kid but love now?”, etc., etc.

I suspect these are just scams to get people’s data, but can find no articles on this. A few years ago, it was easy to find long lists of all the data third parties collected when you joined their groups, but nothing like that comes up anymore in a Google search. (No doubt, FB has tweaked the search results.)

Does anybody have any insights into the risk of answering those inane questions?
