[EX Q]: Question: What country was the creator of "Colonel Jonathan the Saint" born in? Passage:In 1963-1964 Walker was a resident artist at the Oldenburgisches Staatstheater. He then became a resident artist at the Cologne Opera from 1964-1966. Other contracts soon followed with such companies as the Cincinnati Opera, the Houston Grand Opera, the Lyric Opera of Kansas City, the Miami Opera, and the New Orleans Opera among others. In 1971 he created the role of Jonathan Gilourin in the world premiere of Dominick Argento’s Colonel Jonathan the Saint at the Denver Lyric Opera. In 1974 he was handpicked by Sir Georg Solti to sing the role of the Evangelist in Bach's St Matthew Passion with the Chicago Symphony Orchestra (CSO). He returned twice more for performances with Solti and the CSO for performances of the Shepherd in Stravinsky's Oedipus Rex (1976) and Beethoven's Missa Solemnis (1977); the latter of which was recorded for London Records.

[EX Q]: Question: Has the winner of the inaugural NCAA tournament won it more than once? Passage:The first NCAA Tournament was organized by the National Association of Basketball Coaches. Oregon won the inaugural tournament, defeating Ohio State 46–33 in the first championship game. Before the 1941 tournament, control of the event was given to the NCAA. In the early years of the tournament, it was considered less important than the National Invitation Tournament (NIT), a New York City-based event. Teams were able to compete in both events in the same year, and three of those that did so—Utah in 1944, Kentucky in 1949, and City College of New York (CCNY) in 1950—won the NCAA Tournament. The 1949–50 CCNY team won both tournaments (defeating Bradley in both finals), and is the only college basketball team to accomplish this feat. By the mid-1950s, the NCAA Tournament became the more prestigious of the two events, and in 1971 the NCAA barred universities from playing in other tournaments, such as the NIT, if they were invited to the NCAA Tournament. The 2013 championship won by Louisville was the first men's basketball national title to ever be vacated by the NCAA after the school and its coach at the time, Rick Pitino, were implicated in a 2015 sex scandal involving recruits.

[EX Q]: Question: Which of the combined Byzantine-Persian army generals lived longer? Passage:Maurice had to continue the war against the Persians. In 586 his troops defeated them at the Battle of Solachon south of Dara. In 588, a mutiny by unpaid Byzantine troops against their new commander, Priscus, seemed to offer the Sassanids a chance for a breakthrough, but the mutineers themselves repulsed the ensuing Persian offensive. Later in the year they secured a major victory before Martyropolis. The Sassanid commander, Maruzas, was killed, several of the Persian leaders were captured along with 3,000 other prisoners, and only a thousand men survived to reach refuge at Nisibis. The Byzantines secured much booty, including the Persian battle standards, and sent them, along with Maruzas' head, to Maurice in Constantinople. In 590 two Parthian brothers, Vistahm and Vinduyih, overthrew King Hormizd IV and made the latter's son, Prince Khosrau II, the new King. The former Persian commander-in-chief, Bahram Chobin, who had rebelled against Hormizd IV, claimed the throne for himself and defeated Khosrau. Khosrau and the two Parthians fled to the Byzantine court. Although the Senate unanimously advised against it, Maurice helped Khosrau regain his throne with an army of 35,000 men. In 591 the combined Byzantine-Persian army under generals John Mystacon and Narses defeated Bahram Chobin's forces near Ganzak at the Battle of Blarathon. The victory was decisive; Maurice finally brought the war to a successful conclusion with the re-accession of Khosrau.
