[EX Q]: Question: What year did Philby defect? Passage:In May 1986, Souther requested Soviet citizenship, aware that the investigation against him was progressing. In June, fearing imminent arrest, Souther defected to the Soviet Union by flying from the United States to Rome, where the Soviet intelligence services transferred him to Moscow. Initially, Soviet counterintelligence units were suspicious of Souther's defection and feared that he was a double agent for the CIA, but he was cleared shortly afterwards. On 2 October 1986, Souther was granted Soviet citizenship in a decree from the Presidium of the Supreme Soviet, and adopted the Russian name Mikhail Yevgenyevich Orlov. Souther was well-received by the Soviet authorities, gifting him an apartment in Moscow and a dacha on the outskirts of the city, and promoting him to the rank of major in the KGB – one of few foreign spies to be commissioned as an officer in the agency. Souther became actively engaged in scientific activities, developed his own English teaching program, walked around Moscow a lot, and travelled to other Soviet cities. Souther met and befriended other foreign Soviet intelligence agents that had defected including Kim Philby and George Blake. Souther married a Russian woman named Elena, an English teacher at the Intelligence Institute, and they had a daughter named Alexandra. In early 1989, Souther was awarded an Order of Friendship of Peoples for his contributions in the intelligence services following a petition from the KGB leadership.

[EX Q]: Question: Who currently holds the position held by Frank Calder? Passage:The Pittsburgh Pirates are traced back to the Pittsburgh Yellow Jackets of the US Amateur Hockey Association. The Yellow Jackets' owner was Roy Schooley, a former referee. Even though the team won the USAHA Championship in 1924 and 1925, Schooley encountered financial problems. His team was then sold to attorney James F. Callahan. Pittsburgh was granted a franchise by the National Hockey League on November 7, 1925. The move came after Eddie Livingstone, the former owner of the Toronto Shamrocks and the Toronto Blueshirts of the National Hockey Association saw Pittsburgh as a possible member for a proposed rival league to the NHL; Pittsburgh had, in the 1890s, been the first metropolitan area to professionalize the game of ice hockey. In order to thwart the new league, the President of the NHL, Frank Calder, negotiated to put a franchise in Pittsburgh, which become the seventh team to join the NHL as well as the league's third US-based team. Callahan then renamed his team the Pittsburgh Pirates, after he received permission from Barney Dreyfuss, the owner of the Pittsburgh Pirates baseball team.
