Answer:
The correct answers would be: She expanded the Russian Empire, Improved the education system and encouraged greater diversity in Russian architecture.
Step-by-step explanation:
Catherine the Great, who ruled the Russian Empire from 1762 to 1796 and with her arose the Russian Golden Age. She ascended the throne after supporting a coup against her own husband, Peter III and over her own son, Paul I, who should have taken over after his father´s death. Among the many things that the Russian Empress achieved, was a coordination of the newly conquered lands, and a further expansion of the Russian power, a revolution in the educational system, as she established that education, in the European style, improved conditions inside her own empire, and so she fostered a lot of educational institutions. She also encouraged the use of European, and ancient-styled architecture in the empire, bringing diversity to it. She was a great patron of the arts and through her the arts in Russia developed enormously. The only thing that did not happen during this Empress´s reign, was the freedom of serfs. In fact, much of her rule, and her empire, still depended on the work of serfs.
