[EX Q]: Question: Which of the annual events that take place at Expo New Mexico gets more visitors? 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:The city is home of the International Balloon Fiesta, the world's largest gathering of hot-air balloons, taking place every October. The New Mexico State Fair and Gathering of Nations are held annually at Expo New Mexico, other major venues throughout the metropolitan area include the University of New Mexico’s Popejoy Hall, Santa Ana Star Center, Isleta Amphitheater and historic theaters such as the KiMo Theater and El Rey Theater. Old Town Albuquerque hosts traditional fiestas and events such as weddings, and the Civic Plaza, with its Al Hurricane Pavillion and Albuquerque Convention Center, hosts a myriad of events including large concerts and conventions. Due to its population size, the metropolitan area regularly has New Mexico music concerts and receives most of New Mexico’s national and international music concerts, Broadway shows, and other traveling events. Likewise, the city is home to a diverse restaurant scene from various global cuisines and the state’s distinct New Mexican cuisine.
 Passage 3: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.

[EX Q]: Question: How many sales are required to get the certification from the RIAA that Enjoy Yourself recieved in 1989? Passage 1:For 1970, Matra insisted on using their own V12 engines, while Tyrrell and Stewart wanted to continue with the Cosworth and maintain their connection to Ford, which conflicted with Matra's recent connections to Chrysler. Tyrrell decided to build his own car and in the interim bought a chassis from March Engineering; Stewart took the March 701-Cosworth to wins at the Daily Mail Race of Champions and Jarama, but development on the car stalled and it was soon overcome by the Lotus team's new 72. The new Tyrrell 001-Cosworth, appeared in August and suffered problems but showed promise. Tyrrell continued to be sponsored by French fuel company Elf, and Stewart raced in a car painted French Racing Blue for many years. Stewart also continued to race sporadically in Formula Two, winning at Crystal Palace and placing at Thruxton. A projected Le Mans appearance, to co-drive the 4.5 litre Porsche 917K with Steve McQueen, did not come off, due to McQueen's inability to get insurance. He also had a one-off race in Can-Am, in the revolutionary Chaparral 2J. Stewart qualified third, in what was the car's first outing, but brake failure ended his race.
 Passage 2:"Enjoy Yourself" is a song recorded by The Jacksons and released as a single in 1976. Featuring Michael and Jackie Jackson on lead vocals, it was the first non-Motown single for the group since they departed from the label earlier that year. The song peaked at #6 on the Billboard Hot 100 chart on February 19, 1977. On other US charts, "Enjoy Yourself" peaked at #2 on the Hot Soul Singles chart, and #33 on the National Disco Action Top 40 chart. On February 14, 1989, it became the group's first single to be certified Platinum by the RIAA. It was also the group's first song to feature new member Randy Jackson, who replaced Jermaine when he decided to stay at Motown after his brothers left. The song is sampled on the track "Let's Have a Party" by the Backstreet Boys, which appears on their 1996 self-titled debut album. The song is credited to Philadelphia songwriters/producers Gamble and Huff; however, a session musician from Gamble and Huff’s in-house band recalled that the late guitarist T.J. Tindall wrote the riff that was the initial spark for the song.
 Passage 3:Williams quickly reloaded the team with top talent, bringing in recruits like Brandan Wright, Ty Lawson, Wayne Ellington and Deon Thompson. The 2006–07 team tied as ACC regular season champions, earning the tiebreak over the Virginia Cavaliers. With the #1 seed, the Tar Heels won the ACC Tournament. After earning a #1 seed in the East Region in the 2007 NCAA Tournament, Williams' team won its first-round game against Eastern Kentucky Colonels 86–65 and its second against Michigan State 81–67. North Carolina then defeated the USC Trojans 74–64 to advance to the Elite Eight. On March 24, 2007, North Carolina fell to the Georgetown Hoyas in overtime in the East Regional, ending its post-season run. Following the 2006–2007 season, Williams announced on July 18, 2007, that he had vertigo, a condition that occasionally forces him to sit down suddenly during games.

[EX Q]: Question: Who was the wife of the ruler that Vasiliy Buturlin was a representative of when he had a meeting with the Zaporozhian Cossacks? Passage 1:In 1760 the French zoologist Mathurin Jacques Brisson included a description of the purple-throated sunbird in his Ornithologie based on a specimen collected in the Philippines. He used the French name Le grimpereau pourpré des Philippines and the Latin Certhia Philippensis Purpurea. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he added 240 species that had been previously described by Brisson. One of these was the purple-throated sunbird. Linnaeus included a brief description, coined the binomial name Certhia sperata and cited Brisson's work. Linnaeus specified the type location as the Philippines but this was subsequently restricted to Manila. The specific name sperata is Latin for "bride" or "betrothed". The species is now placed in the genus Leptocoma that was introduced by the German ornithologist Jean Cabanis in 1850.
 Passage 2:At a meeting between the council of Zaporozhian Cossacks and Vasiliy Buturlin, representative of Tsar Alexey I of the Tsardom of Russia, during the Khmelnytsky Uprising. The "Pereyaslav Council" (Pereyaslavs'ka Rada in Ukrainian) of Ukrainians took place on January 18; it was meant to act as the supreme Cossack council and demonstrate the unity and determination of the "Rus' nation". Military leaders and representatives of regiments, nobles and townspeople listened to the speech by the Cossack hetman Bohdan Khmelnytsky, who expounded the necessity of seeking the Russian protection. The audience responded with applause and consent. The treaty, initiated with Buturlin later on the same day, invoked only protection of the Cossack state by the Tsar and was intended as an act of official separation of Ukraine from the Polish–Lithuanian Commonwealth (Ukrainian independence had been informally declared earlier in the course of the Uprising by Khmelnytsky). Participants in the preparation of the treaty at Pereyaslav included, besides Khmelnytsky, Chief Scribe Ivan Vyhovsky and numerous other Cossack elders, as well as a large visiting contingent from Russia.
 Passage 3:Kato was born in Ageo on 11 December 1984. He joined J1 League club Urawa Reds from youth team in 2003. Although Reds won the many title 2006 J1 League, 2007 AFC Champions League and so on, he could hardly play in the match behind Ryota Tsuzuki and Norihiro Yamagishi until 2010. He became a regular goalkeeper in 2011 and Reds won the 2nd place in 2011 and 2013 J.League Cup. However he lost his regular position behind Shusaku Nishikawa in 2014. In 2015, he moved to Saitama's cross town rivals, Omiya Ardija in J2 League. He played as regular goalkeeper and Ardija was promoted to J1 end of 2015 season. Although his opportunity to play decreased from 2016, he played many matches while battling with Hitoshi Shiota for the position. However Ardija finished at the bottom place in 2017 season and was relegated to J2. He could not play at all in the match behind Takashi Kasahara in 2018. In 2019, he moved to J2 club Kyoto Sanga FC.
