That comes awfully close to saying that if you write an article arguing
for some position, and I write another article arguing against yours,
that my work is a derivative of yours, even if I don't quote you (or at
least not beyond fair use/fair dealing).  That seems to me a socially
dangerous position (it would make life hard for lawyers!).

In particular, there exists the C Answer Book (Tondo & Gimpel), which
gives answers to the study questions in The C Programming Language
(Kernighan & Ritchie).  I can't see that it is a derivative work, even
though it is hardly usable without K&R.
