Check: this paper's printed header reads "10-Met-B6, Physical Metallurgy of Iron and Steel," and all seven questions are ferrous physical metallurgy (interstitial-solubility/martensite-strengthening MC–TF items, schematic hypo-/hypereutectoid microstructures, CCT-curve construction and the TTT “C” shape, high-speed tool-steel heat treatment, cast-iron ductility, martensite tempering, and austempering of strapping steel) with no ceramics content anywhere.
