[EX Q]: Question: What was the size of Princeton's endowment the year Beale was born? Passage 1:Un'yō  was one of the ships dispatched to Kyūshū in 1874 during the Saga Rebellion. In May 1875, she carried diplomats to Busan in Korea in an attempt by the Japanese government to open diplomatic relations with the Joseon dynasty government. After they were rebuffed in these negotiations, the Japanese government again dispatched Un'yō in September 1875 under the command of Inoue Yoshika to provoke a military response, in what was later termed the Ganghwa Island incident. This eventually led to the Treaty of Ganghwa, which opened the Korean Peninsula to Japanese trade. In 1876, Un'yō  was assigned to assist in the suppression of the Hagi Rebellion, another uprising of disaffected former samurai. Un'yō  was severely damaged when she ran aground off the coast of the Kii Peninsula, and was scrapped the following year.
 Passage 2:Beale was born in 1948 in St. Louis County, Minnesota to C. Gordon Beale, a minister of the United Church of Christ, and Marcella Beale, a nurse. He served in the United States Army as a medic in the early 1970s and was honorably discharged. Beale attended the University of California, Riverside, earning a bachelor's degree in political science in 1975, using resources provided by the G.I. Bill. Beale interned for Democrat US Senator John V. Tunney while in college, assisting in the negotiation of the Bilingual Courts Act. He later simultaneously earned a Master of Public Administration from Princeton University and a law degree from New York University. Beale was employed with a law firm consisting of three partners in Lake City, Minnesota for four years prior to his work with the EPA. During his time with this law firm, he primarily dealt with the Federal Election Commission and the Securities and Exchange Commission.
 Passage 3:Cecil's success in 2011 was partly due to his training of the Khalid Abdullah-owned Frankel. In the 2010 season Frankel won the Royal Lodge Stakes and Group One Dewhurst Stakes. The following year he continued unbeaten, winning the Greenham Stakes, the 2,000 Guineas, the St. James's Palace Stakes at Royal Ascot, the Sussex Stakes and the Queen Elizabeth II Stakes. His six length victory in the 2,000 Guineas was described as "one of the greatest displays on a British racecourse". After his win in the Sussex Stakes Cecil himself described Frankel as "the best horse I've ever seen". Timeform and the International Federation of Horseracing Authorities rated him the best horse in the world. In his four-year-old season Frankel won the Group One Lockinge Stakes at Newbury before an eleven length victory in the Queen Anne Stakes at Royal Ascot, described in one national newspaper as "possibly the best single performance by any horse, on any track, since three Arabian stallions were imported into Britain to found the thoroughbred breed in the early years of the 18th century". Timeform raised their rating to 147, making Frankel the highest rated horse in their history. He won a second Sussex Stakes, at odds of 1–20, and then stepped up in distance to win by seven lengths the Juddmonte International Stakes at York over 10 furlongs. In October 2012 Frankel won the Champion Stakes at Ascot to finish his career unbeaten. "He's the best I've ever had, the best I've ever seen", Cecil told the BBC after the race, "I'd be very surprised if there's ever been a better."

[EX Q]: Question: How old was the person who chaired the AUKcon convention held in February 1994 in London? Passage 1:While still a youth in 265 BC, Fabius was consecrated an augur. It is unknown whether he participated in the First Punic War, fought between the Roman Republic and Carthage from 264 to 241 BC, or what his role might have been. Fabius' political career began in the years following that war. He was probably quaestor in 237 or 236 BC, and curule aedile about 235. During his first consulship, in 233 BC, Fabius was awarded a triumph for his victory over the Ligurians, whom he defeated and drove into the Alps. He was censor in 230, then consul a second time in 228. It is possible that he held the office of dictator for a first time around this time: according to Livy, Fabius's tenure of the dictatorship in 217 was his second term in that office, with Gaius Flaminius as his deputy and magister equitum during the first term: however Plutarch suggests that Flaminius was deputy instead to Marcus Minucius Rufus - presumably Fabius's great political rival of that name, who later served as deputy to Fabius himself (see below). It is of course possible that Flaminius was successively deputy to both, after Minucius's apparently premature deposition following bad augural omens: and also possible that little of note (other than, possibly, holding elections during the absence of consuls) was accomplished during either dictatorship.
 Passage 2:During the Winter 2017 TCA Press Tour, series mainstays Sarah Paulson and Evan Peters were reported to be starring as the leads in the season. In March 2017, Billy on the Street host Billy Eichner was announced to be cast in the series, playing a role in the life of Paulson's character. His character is slated for appearing in "six or seven" episodes. The next month, it was reported that Scream Queens actress Billie Lourd will also star in the seventh installment of the series. In May 2017, Leslie Grossman, who starred in Murphy's series Popular, joined the cast of the series, and Angela Bassett hinted she may return in a recurring role. Despite this, Bassett didn't appear, but she did direct the episode "Drink the Kool-Aid". Later that month, it was confirmed via set pictures that Adina Porter and Cheyenne Jackson were also returning. In June 2017, Murphy confirmed via his Instagram account that Colton Haynes, whom Murphy worked with previously on second season of Scream Queens, was joining the casting for the seventh season. Later that month, set pictures revealed that Alison Pill was joining the cast of the season, seemingly portraying the partner of Sarah Paulson's character. In July 2017, Murphy revealed via his Twitter account that Lena Dunham was joining the season. She is set to play Valerie Solanas, author of the SCUM Manifesto and attempted murder of Andy Warhol, via flashbacks. Murphy also confirmed the returns of Frances Conroy and Mare Winningham. Conroy has appeared in all the seasons except Hotel, while Winningham has appeared in Coven, Freak Show, and Hotel. In August 2017, Murphy confirmed the return of Emma Roberts, who appeared in Coven and Freak Show, while Roanoke actors Chaz Bono and James Morosini also confirmed their returns. In the seventh episode, Murder House, Coven, and Freak Show actress Jamie Brewer returned to the show.
 Passage 3:AUKcon was a one-day anime convention held in London, England, on 19 February 1994. The venue was the Conway Hall (Red Lion Square), and the registration charge was £10. AUKCon was chaired by Helen McCarthy. During the convention, Lawrence Guinness of Manga Video announced that the company had acquired distribution rights for Ranma 1/2 and planned to start releasing it in 1994. Also announced included plans for the series Bio Booster Armor Guyver. One of the guests that attended was Toren Smith, writer of the American Dirty Pair comic and founder of Studio Proteus. The convention was the first UK anime event to provide a fan room with free space for fanzines and fanclubs. It also ran a gaming programme and an art and model show, as well as anime screenings and talks.

[EX Q]: Question: What age was Stalin when he gave Pomeranchuk an order to go to Sarov? Passage 1:After Landau moved to the Kapitza institute in Moscow (to avoid arrest for comparing Stalinism to Nazism), Pomeranchuk also moved there, working for the tanning industry. He returned to Leningrad in 1938, lecturing, completing his Ph.D. and becoming employed as a junior scientist. He joined the Lebedev Institute of the Academy of Sciences of the USSR in Moscow as a senior scientist in 1940. In 1941 the institute was evacuated to Kazan. Under Abraham Alikhanov, he studied cosmic rays in Armenia from 1942. In 1943, he transferred to Laboratory No.2 under Igor Kurchatov as part of the Soviet project to develop nuclear weapons. Alikhanov founded Laboratory No.3 (which became the Institute for Theoretical and Experimental Physics (ITEP)) and Pomeranchuk worked there from 1946 (and for the rest of his life), founding and leading the Theoretical department, as well as being Professor of Theoretical Physics at the Moscow Mechanical Institute where students admired his infectious enthusiasm for his subject. Rudolf Peierls was consoled by the fact that it was "very clever Pomeranchuk" - and no-one else - who corrected his 1/T law for heat conduction in high-temperature condensed matter physics. His work in the 1940s was dominated by neutron research and his manuscript with Akhiezer was the basic guide for Soviet nuclear reactor construction. In 1950, he published a paper suggesting that the entropy of helium-3 as a liquid was less than as a solid. In 1950, Pomeranchuk received an order from Josef Stalin to go to Arzamas-16, located in the closed city of Sarov, Nizhny Novgorod region, to work on Soviet nuclear weaponry. Missing his family and his 'hobby physics' problems, he was advised not to apply for a revocation but wait until the order was "forgotten." He returned to ITEP within a year. He continued enthusiastically with work on quantum field theory and S-matrix theory, particle collisions and Regge theory, the latter in vigorous collaboration with Vladimir Gribov. His last paper on Regge theory was published posthumously. For his work, Pomeranchuk was twice awarded the Stalin Prize (1950, 1952). He was elected a corresponding member of the Academy of Sciences of the USSR in 1953 and full member in 1964.
 Passage 2:McCammon never played in the NHL, spending his entire career in the minor leagues. He was the head coach of the Maine Mariners of the American Hockey League and won the Calder Cup in 1977-78 and 1978–79, the first two years of the team's existence. McCammon had two stints as head coach of the Philadelphia Flyers, also serving as the team's general manager during the latter. He was also the head coach of the Vancouver Canucks and an assistant coach for the Edmonton Oilers on two different occasions. With Vancouver in 1988–89, he was runner-up to Pat Burns of the Montreal Canadiens for the Jack Adams Trophy as NHL Coach of the Year. He won the Stanley Cup with the Edmonton Oilers in 1987 as director of player development, and in 2002 and 2008 as a scout with Detroit. McCammon's name was added to the Stanley Cup in 2002 with Detroit. 
 Passage 3:After playing junior hockey for the Sioux Falls Stampede of the United States Hockey League (USHL), Vanek joined the University of Minnesota Golden Gophers, leading the team in goals (31), assists (31) and points (62) in the 2002–03 season. In part due to his prolific scoring touch, the Golden Gophers won the 2003 NCAA National Championship. Vanek was named MVP of the Frozen Four tournament, scoring the game-winning goals in both the semifinal against Michigan in overtime and in the final against New Hampshire. He was also named Minnesota's team MVP for 2003, becoming the first freshman to receive the honor. He scored the most points by a Golden Gopher freshman in 2003 since Aaron Broten who scored 72 total points in 1979–80. He was the first freshman to lead the team in scoring since Mike Antonovich in 1969–70. His 31 goals also led all NCAA freshmen in goal scoring, and was fourth in the entire country. He was also the 2003 WCHA Rookie of the Year, the third Golden Gopher to win the award.
