explanation: "chemistry" belongs to "natural science", and the object of "natural science" research includes "chemical elements". "history" belongs to "humanities", and the objects of "humanities" research include "historical figures".  "physics" does not entirely belong to "biophysics" "linguistics" is a language, and "chinese language" is the study of human language. "sociology" is a type of "social science", and the word order is inconsistent with the query.
