Which lists types of materials from most conductive to least conductive?

a. insulator, semiconductor, conductor, superconductor
b. superconductor, conductor, semiconductor, insulator
c. conductor, insulator, semiconductor, superconductor
d. semiconductor, conductor, superconductor, insulator

The answer is B. superconductor, conductor, semiconductor, insulator. Logically, one can look at the prefixes to determine the over conductive strength of each word. A superconductor would readily conduct, even at low temperatures. A semiconductor would have the conductive strength between an insulator and a conductor. Conductor therefore is logically between a semiconductor and superconductor. Finally, an insulator has the lowest conductive strength.
