Q:Question: "Begun in 1759 what was being completed on the Winter Palace by Empress Elizabeth?"  Context: "Many middle and small powers in Europe, unlike in the previous wars, tried to steer clear away from the escalating conflict, even though they had interests in the conflict or with the belligerents, like Denmark-Norway. The Dutch Republic, long-time British ally, kept its neutrality intact, fearing the odds against Britain and Prussia fighting the great powers of Europe, even tried to prevent Britain's domination in India. Naples, Sicily, and Savoy, although sided with Franco-Spanish party, declined to join the coalition under the fear of British power. The taxation needed for war caused the Russian people considerable hardship, being added to the taxation of salt and alcohol begun by Empress Elizabeth in 1759 to complete her addition to the Winter Palace. Like Sweden, Russia concluded a separate peace with Prussia."  Answer:
A:
her addition
