Question: What was Joseph Stalin's title when Ohloblyn lost his job at Kiev University because of Stalin's purges? Passage 1:In 2019, Alexandrova had more success in the WTA Tour. Seeded sixth, she reached the quarterfinals of the St. Petersburg Ladies' Trophy, followed by a semifinal entry at the Hungarian Ladies Open. She entered the 3rd Round of the Premier Mandatory BNP Paribas Open in Indian Wells, after beating World No. 13 Caroline Wozniacki in three sets. She performed not satisfying on clay tournaments, except at French Open, reaching the third round of a Grand Slam tournament for the first time. In the grass court season, Alexandrova made it into the quarterfinals of the Premier Eastbourne International tournament, losing there to Karolina Pliskova. She achieved her best run in a Premier 5 tournament at the Rogers Cup, reaching the 3rd Round as qualifier. She lost to Serena Williams. After reaching the 2nd Round of the US Open and following Daria Kasatkina's 1st Round loss, Alexandrova became Russia's number one female tennis player.
 Passage 2:Spokane Arena, in addition to its duties as being the host of Chiefs and Shock games, also has served as a secondary home for the men's basketball programs of Gonzaga University and Washington State University for nearly every year since opened. Washington State has played 33 matchups in the Spokane Arena in 19 of the 22 years with a record of 18–15 (1–7 vs. ranked opponents), while Gonzaga has hosted 18 games in 15 of the 22 years with a record of 12–6 (1–2 vs. ranked opposition). In-state rivals Washington State and Gonzaga have faced off against each other in the arena on five occasions (1995, 1996, 1998, 1999, and 2014) with the Zags owning a 3–2 record against the Cougars in those games. The Bulldogs' faced off against local rival Eastern Washington University at the arena in four consecutive years (2002, 2003, 2004, and 2005), each won by the Zags, but just like with the Cougars, the rivalry has gone dormant due to the rise of the Zags' program to major status since the late 1990s, while the Cougars and Eagles have not seen much national spotlight. Washington State has often hosted home games at the Spokane Arena as a part of its Pac-12 Conference men's basketball schedule, holding a 7–9 against conference foes in the arena, facing UCLA (1996 and 2004), Oregon (1997 and 2011), Oregon State (1997, 2011, and 2017), Arizona (1998, 2001, and 2006), Washington (1999), USC (2000 and 2004), Stanford (2004), California (2005), and Colorado (2014). With Gonzaga's rise to prominence, the Zags were able to bring high major schools like Washington (1998), Georgia (2003), Memphis (2007, 2009, and 2011) and Oklahoma (2009) to the Spokane Arena, with the Gonzaga holding a 2–3 record in those matchups, but with conference realignment and the West Coast Conference's additions of BYU (2011) and Pacific (2013), the Zags have been more selective and limited in their scheduling with four less matchups in their non-conference schedule, so they have only played in the Spokane Arena once since 2012.
 Passage 3: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.
