[EX Q]: Question: How many other operas did the composers of Patience write? Passage:In September 2005, Ball made his New York City Opera debut as Reginald Bunthorne in Gilbert and Sullivan's Patience. He spent the first quarter of 2006 on complete vocal rest, following the illness that caused him to leave The Woman in White on Broadway. By the middle of July, Ball had taken part in the Royal Court Theatre's celebratory performance of The Rocky Horror Show. He took a leading role in Kismet in June and July 2007 for the ENO, and appeared on Channel 4's Richard & Judy on 22 June 2007 to promote this production. He then appeared as the solo artist in a controversial 'Musical Theatre' Prom on 27 August 2007 for the BBC at London's Royal Albert Hall. Ball performed a wide range of musical theatre numbers, including several by Andrew Lloyd Webber. The show was broadcast live on BBC Four, as well as on BBC Radio 3.

[EX Q]: Question: Who appeared with Alan Napier in the film that was released in 1943? Passage:He made his American stage debut as the romantic lead opposite Gladys George in Lady in Waiting. Though his film career had begun in Britain in the 1930s, he had very little success before the cameras until he joined the British expatriate community in Hollywood in 1941. There he spent time with such people as James Whale, a fellow ex-Oxford Player. He appeared in such films as Random Harvest (1942), Cat People (1942), and The Uninvited (1944). In The Song of Bernadette (1943), he played the ethically questionable psychiatrist who is hired to declare Bernadette mentally ill. He also played the vicious Earl of Warwick in Joan of Arc (1948). He performed in two Shakespearean films: the Orson Welles Macbeth (1948), in which he played a priest that Welles added to the story, who spoke lines originally uttered by other characters, and MGM's Julius Caesar (1953), as Cicero. He appeared as Mr. Rutland in the Hitchcock movie Marnie (1964).

[EX Q]: Question: Who was the president of Harvard University when Ohloblyn began teaching history there as a visiting professor? Passage:Ohloblyn traced his ancestry to the Novgorod-Siversky region of Left-bank Ukraine, which had formed an important part of the autonomous Ukrainian "Hetmanate" in the seventeenth and eighteenth centuries, and throughout his professional career as a historian retained a lively interest in this area and wrote frequently about it. Educated at the universities in Kiev, Odessa, and Moscow, from 1921 to 1933 he taught history at the Kiev Institute of People's Education (as Kiev University was known after the revolution), but during Joseph Stalin's purges, was dismissed from his posts, forced to recant his allegedly "bourgeois nationalist" views, and suffered repression including several months of imprisonment. In the late 1930s he returned to teaching at Kiev and Odessa universities. When the Germans occupied Kiev in the fall of 1941, Ohloblyn was appointed head of the Kiev Municipal Council, a post which he held from September 21 to October 25, and was a member of the Ukrainian National Council which tried to organize Ukrainian life under the difficult conditions of the occupation. He desperately tried to save from execution some of Jews he knew but the German commandant of Kiev informed him that "the Jewish issue belongs to exclusive jurisdiction of Germans and they will solve it at their own discretion" (, in Russian). Politics under the Nazis was not to his taste and he quickly retired from his public positions and returned to his scholarly work. In 1942 he worked as a director of Kiev Museum-Archive of Transitional Period, whose exhibition compared life under Bolsheviks and under Germans. In 1943 he moved to Lviv in western Ukraine and in 1944 to Prague. Upon the approach of the Red Army, he fled west to Bavaria. From 1946 to 1951, he taught at the Ukrainian Free University in Munich. In 1951, he moved to the United States where he was active in various Ukrainian emigre scholarly institutions such as the Ukrainian Academy of Arts and Sciences in the US and the Ukrainian Historical Association. From 1968 to 1970, he was a Visiting Professor of History at Harvard University.
