Input: Consider Input: Question: Is Vitebsk the capital of a country? Passage:A.P. Rosengolts was born in Vitebsk on November 4, 1889. He was the son of a Jewish merchant. He joined the Bolshevik faction of the Russian Social-Democratic Workers' Party (RSDRP) in 1905, the year of the first, abortive Russian Revolution. He worked as an insurance agent and carried out work for the Bolshevik party in Vitebsk, Kiev, Ekaterinoslav and Moscow. Rosengolts played an active role in the Revolution of 1917. He was a member of the Executive Committee of the Moscow City Council, the Moscow Military-Revolutionary Committee and the All-Russian Military-Revolutionary Committee. He was a leading officer in the Red Army and, during the Russian Civil War, worked closely with L.D. Trotsky. After the Civil War, Rosengolts worked successively for the Commissariats of Transportation and Finance and the Directorate of the Red Army Air Force. He served as ambassador to Britain from 1925 to 1927 and oversaw Soviet espionage in Britain. He became a member of the Central Committee of the Communist Party of the Soviet Union in 1927 and held various high positions in the Communist Party and the Soviet government. In 1930 he was appointed People's Commissar of Foreign Trade. On June 14, 1937, Rosengolts was dismissed from this office and on October 7, 1937, he was arrested. He was one of the defendants of the third Moscow Trial, along with Nikolai Bukharin, Alexey Rykov and other prominent Soviet officials. The accused faced a long list of capital charges, including plotting to assassinate Lenin and Stalin, espionage and sabotage. Like most of his co-defendants, Rosengolts confessed. He was convicted, sentenced to death and shot on March 15, 1938 in Moscow. He was rehabilitated in 1988.

Input: Consider Input: Question: Who is the mayor of the city where Whistle Down the Wind, opened in December 1996? Passage:Steinman provided lyrics for Andrew Lloyd Webber's musical Whistle Down the Wind, which opened in Washington, D.C. in December 1996. However, it received poor reviews and the Broadway run, scheduled for the following April, was cancelled. A reworked and more successful West End production opened at the Aldwych Theatre on July 1, 1998. In addition to a full-length cast album for the London production, an album was released of well-known performers singing pop versions of the songs from the show. This album was produced by Steinman, as usual with Steven Rinkoff. Those performers include Tom Jones, Tina Arena, Boyzone, Elaine Paige, Donny Osmond, The Everly Brothers, Meat Loaf, Boy George, Sounds of Blackness, Bonnie Tyler, Michael Ball, and Lottie Mayor. One track, "No Matter What" performed by Boyzone, reached the peak position on the pop charts in many countries. The same track appeared on a Boyzone album and their greatest hits album. As of 2019, Boyzone's 1998 recording of "No Matter What" is the most recent new song or project written at least in part by Steinman, or to contain any new work of his at all, to achieve major, chart-topping success. The track "Whistle Down the Wind", performed by Tina Arena, from the same album, also had some chart success. There was also a single released in the U.K., for charity, of children from Red Hill Primary School and Sylvia Young Theatre School performing "When Children Rule The World". The singers were called the "Red Hill Children", and the single peaked at #40 on the U.K. singles charts.
