Active Galaxies, Quasars, and Supermassive Black Holes

A self-checking practice quiz on active galaxies and quasars: active galaxies, supermassive black holes as their engines, quasars, jets and radio galaxies, the types of active galaxies, black holes and galaxy evolution, and how they are observed. Every question is multiple choice and shown one at a time, and the set is drawn fresh each time you take it. At the end you receive a report showing how many you answered correctly.
