Questions form hierarchies in which more specific questions are [[Subquestion| subquestions]] of more general ones. Theories also enter into this hierarchy, since questions presuppose theories, and theories are answers to questions.

They are identified as such in the discipline's [[Delineating Theory| delineating theory]].
