That's not how copyright works. Simply rewording each question will still violate copyright when you're copying all of the questions. I couldn't just reword Harry Potter and republish all of the novels. Likewise, copying some small portion may fall under fair use.
I believe (and I’m not a legal expert here), that what the commenter is alluding to is the “moral rights” over a work. This is more common in the UK and Canada. When I worked for a Canadian company (I’m a U.S. American) part of our IP release for works-for-hire included a waiver/transfer of rights specifically for the “moral” or “authors” rights, which were explained as being the “spirit” or “whole” of works we created.
It’s a legal construct, but I was never satisfied with that explanation. The gist was that while we could transform things that we learned or did, we could not re-use the ideas that formed the functioning product in other works elsewhere, even by transformation.
Doesn’t the Berne convention specifically make moral rights inalienable? The whole point being that you may transfer redistribution rights, etc. to somebody else, but they still don’t get to (affirmatively) claim they wrote it (thus can’t even try to pressure you to allow it)? Am I misunderstanding or is the local (and likely original) definition of “moral rights” different from the one in the convention?
