[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: When did Pennsylvania Route 5 get its colloquial name? Passage 1:After attending Canton McKinley High School, where they won the 1981 Ohio High School Athletic Association football championships, he went to the University of Michigan where he became the only freshman varsity letter winner on the football team in 1983. Rivers, who wore #13 as a Wolverine, started 32 consecutive games until a shoulder injury caused him to end the streak. He posted six interceptions in his Michigan career, including one for a touchdown. Another one during the same season was a game saving interception in the 1986 Fiesta Bowl in a 27–23 victory over the Nebraska Cornhuskers football team. Rivers started 12 of the 13 games his senior season for the Big Ten Conference champions and was one of three All-Americans (along with Jumbo Elliott & Jim Harbaugh) that season as the team went 11–2 and was invited to the Rose Bowl. Rivers once had 17 tackles and an assist as a sophomore defensive back in a game against the 1984 National Champion Brigham Young Cougars football team in the 1984 Holiday Bowl. 17 tackles continues to stand alone as a school single game record.
 Passage 2:Erie is well connected to the Interstate Highway System. There are six "Erie exits" along Interstate 90, a major cross-country thoroughfare running from Boston to Seattle. Erie is the northern terminus of Interstate 79, which travels south to Pittsburgh and, ultimately, West Virginia. The western terminus for Interstate 86, also called the "Southern Tier Expressway," is at Interstate 90 between Erie and North East, Pennsylvania. Interstate 86 continues east through New York to Binghamton.
