[EX Q]: Question: Which of Shapovalov's opponents at Gatineau and Drummondville was younger? Passage:In March in Gatineau, Shapovalov captured his fourth ITF Futures singles title after defeating Gleb Sakharov in straight sets. Two weeks later, he won his first ATP Challenger title with a victory over Ruben Bemelmans at the 75K in Drummondville, and was the youngest Canadian to win a Challenger until Félix Auger-Aliassime's victory at the Open Sopra Steria de Lyon later in the year. The next week, he was defeated by Mirza Bašić in the final of the ATP Challenger 50K in Guadalajara, stopping his winning streak at 17 matches. At the French Open in May, his first professional Grand Slam, he was defeated in the first round of qualifying by the first seed Marius Copil in three sets. In June, Shapovalov qualified for the ATP 500 at the Queen's Club Championships, his fourth ATP main draw but his first as a qualifier. In the first round, he defeated his second top 50 player, world No. 47 Kyle Edmund, before losing to world No. 14 Tomáš Berdych. At Wimbledon in July, Shapovalov was awarded a wild card for the main draw. He was defeated by Jerzy Janowicz in the opening round. At the end of the month, he won his second ATP Challenger title, defeating compatriot Peter Polansky in the final of the 75K in Gatineau.

[EX Q]: Question: How many years were there between the release of the Super Famicom and the beginning of Mother 3 development? Passage:Mother 3 was originally developed for the Super Famicom (Super Nintendo Entertainment System) beginning in 1994. Shigeru Miyamoto, head of Nintendo Entertainment Analysis & Development and Mother 3 producer, said that Mother 3 was "a commercial decision", since Mother 2 (EarthBound outside Japan) had sold well. By this point, Mother series creator Shigesato Itoi had worked on the series' earlier games and Itoi Shigesato no Bass Tsuri No. 1 and was experienced at pitching video games, so Miyamoto provided a team willingly. The Mother 2 development team carried over to the new game's development, though several people left and the team grew in size. They forewent the usual prototyping phase and went straight into development expecting to create something unprecedented. Itoi said he wanted to make the game like a Hollywood film. In September 1994, he predicted that Mother 3 development would end around 1996 with a release on Nintendo's then-upcoming console. The team was inspired by Super Mario 64 and felt that they too could creatively flourish by making a 3D world without restrictions. Their early technical specifications exceeded the capabilities and memory limits of the platform. About halfway through development, the team attempted to scale back its large scope and changed its development platform to the 64DD, a Nintendo 64 expansion peripheral. At E3 in June 1997, Miyamoto speculated that Mother 3 would be one of the four titles for the then-expected 1998 launch of the Japan-only peripheral, but the game was instead converted to a Nintendo 64 cartridge-only format upon the commercial failure of the repeatedly delayed 64DD.

[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.
