Q: Passage: The construction of the cathedral was approved in 1894 by the Ministry of Internal Affairs under Tsarist Russia. Groundbreaking was in 1899; construction work began in 1901 and was completed ten years later. Three-aisled and built from red brick, the cathedral is based on a design by architect Tomasz Bohdanowicz-Dworzecki. The style was influenced by Westminster Abbey and Milan Cathedral. With the help of funds from Catholic parishes in Russia and its neighbouring states, the church was consecrated as a chapel for Moscow's Polish parish in 1911. In the aftermath of the Russian Revolution in 1917, the Provisional Government was overthrown by the Bolsheviks and Russia eventually became part of the Soviet Union in 1922. Because the promotion of state atheism was a part of Marxist–Leninist ideology, the government ordered many churches closed; the cathedral was closed in 1938. During World War II, it was threatened with demolition, and was used after the war for civil purposes, as a warehouse and then a hostel. Following the fall of communism in 1991, it returned to being a church in 1996. In 2002 it was elevated to the status of cathedral. Following an extensive and costly programme of reconstruction and refurbishment, the cathedral was reconsecrated in 2005.

Q: Passage: When the Gilbert and Sullivan partnership collapsed after the production of The Gondoliers in 1889, their producer Richard D'Oyly Carte struggled to find successful new works to show at the Savoy Theatre. Carte produced Sullivan's grand opera, Ivanhoe at another theatre, and afterwards, he turned to Sullivan to create more comic operas for the Savoy. With Sydney Grundy, Sullivan wrote the nostalgic and sentimental Haddon Hall (1892) then, reunited with W. S. Gilbert, he produced Utopia, Limited (1893). He next returned, with his earlier collaborator F. C. Burnand, with The Chieftain (1894) and collaborated for the last time with Gilbert on The Grand Duke (1896). None of these had proved to be more than modestly successful, and Carte's other new pieces for the Savoy in the 1890s had done no better. Following the success of Sullivan's ballet Victoria and Merrie England in 1897, Carte asked Sullivan to work on another new opera for the Savoy.
