PROBLEM: Question: What was the enrollment at Norwegian Academy of Music in 1954? Passage 1:Elvestrand was born in Østre Gausdal. His father was an organist at Østre Gausdal Church and Follebu Church, and he allowed Magne to play there in 1927. Elvestrand studied organ under Arild Sandvold and Fartein Valen, who dedicated his opus 33 to him, and studied theory, harmony, and counterpoint under Gustav Fredrik Lange and Per Steenberg. At the age of 18 he was made cathedral organist at Oslo Cathedral while Eyvind Alnæs was ill and then continued in this function after Alnæs's death until Sandvold was appointed to the position. During the commemoration of the 200th anniversary of Bach's death in 1950, Elvestrand played all of Bach's works at Grefsen Church, where he was organist from 1940 to 1967. He debuted as a pianist in 1956, and he performed his first full harpsichord concert in Copenhagen in 1962. Elvestrand served as the organist at Trinity Church in Oslo from 1967 to 1984. As a teacher, he worked at the Oslo Conservatory of Music from 1942 to 1954 and from 1966 to 1973, at the Norwegian Academy of Music from 1973 to 1984, and at the Huseby public school for the blind from 1952 to 1975. He retired in 1981. Elvestrand's solo album was nominated for the 1977 Spelleman Awards in the classical/contemporary music category, but the award was won by Grex Vocalis. Elvestrand died in Germany.
 Passage 2:The band signed to Earache Records in the late 1980s and released their influential debut album, Streetcleaner (1989), to critical acclaim. After the release of Pure (1992) and their major label debut Selfless (1994), they started experimenting with live drums, as well as with hip hop and breakbeat sounds. The resulting albums, Songs of Love and Hate (1996) and Us and Them (1999), were followed by Hymns (2001), which saw a simplification of the band's sound. Shortly after Green's departure in 2002, Broadrick ended Godflesh and pursued various other projects, including Jesu. Broadrick and Green reformed Godflesh in 2010, releasing A World Lit Only by Fire (2014) and Post Self (2017) to critical acclaim.
 Passage 3:McGarrity won the Formula Ford Festival in 1995 after finishing second in the British Formula Ford series. He was nominated for the McLaren Autosport BRDC Award but it went to fellow Northern Ireland driver Jonny Kane. In 1996 he drove in Formula Opel and the following year he drove in the British Formula Three Championship where he finished 10th. In 1998 he moved up to Formula 3000 where he competed in the first five races for Raceprep Motorsport and rounds 7 through 9 for Nordic Racing. He competed full-time in 1999 for Nordic Racing and finished 10th in points despite only finishing in the points once, finishing on the podium in second in the season opener at Imola. He returned to the team and series in 2000, this time with teammate Justin Wilson. He finished 20th in points with a best finish of 4th at Monaco. In 2001 he left formula cars for sports car racing and drove in the 2001 24 Hours of Le Mans for the MG factory team, but the car failed to finish. He drove the same car in 2002 but the result was the same. He returned to the race in 2004 driving a Bioethanol powered Reynard-Judd for Team Nasamax, finishing the race 17th overall. He drove part-time in the Le Mans Series in 2006. He then joined McLaren Automotive as full-time test driver for the new McLaren car project the MP4-12C from the start of the project.

PROBLEM: Question: Which of the lines that uses the A-series trains began first? Passage 1:NSB Class 73 () is a class of 22 electric multiple units built by Adtranz for the Norwegian State Railways. The four-car trains were modifications of Class 71, which was again based on the Swedish X2. The A-series consists of 16 intercity trains; they were delivered in 1999 and 2000 and are used on the Bergen, Dovre and Sørland Lines. The intercity service was branded as Signatur until 2003. The B-series consists of six regional trains delivered in 2002 and used on the Østfold Line. The regional trains were originally part of the Agenda concept. The trains have a power output of and a maximum speed of . They have an overall length of and have a capacity for 208 seated passengers in the A-series and 250 in the B-series. The trains have a tilting mechanism allowing for faster travel through curves.
 Passage 2:Sculptures of Tubman have been placed in several American cities. A 1993 Underground Railroad memorial fashioned by Ed Dwight in Battle Creek, Michigan features Tubman leading a group of slaves to freedom. In 1995, sculptor Jane DeDecker created a statue of Tubman leading a child, which was placed in Mesa, Arizona. Copies of DeDecker's statue were subsequently installed in several other cities, including one at Brenau University in Gainesville, Georgia. It was the first statue honoring Tubman at an institution in the Old South. The city of Boston commissioned Step on Board, a 10-foot-tall bronze sculpture by artist Fern Cunningham placed at the entrance to Harriet Tubman Park in 1999. It was the first memorial to a woman on city-owned land. Swing Low, a 13-foot statue of Tubman by Alison Saar, was erected in Manhattan in 2008. In 2009, Salisbury University in Salisbury, Maryland unveiled a statue created by James Hill, an arts professor at the university. It was the first sculpture of Tubman placed in the region where she was born.
 Passage 3:Creditsafe was founded in 1997 in Oslo, Norway with the idea of using the then emerging technology of the internet to supply business information to a market of smaller and medium-sized businesses by selling over the telephone and delivering reports over the internet. Following the Norwegian launch Creditsafe established an office in Gothenburg Sweden in 1998 before moving to the UK in 2000. Creditsafe re-located the UK sales operation to Caerphilly in South Wales in 2002. In 2006 Creditsafe France was launched in Roubaix near Lille. Additional entities were later launched in Dublin in Ireland in 2007, The Hague in the Netherlands in 2008, Berlin, Germany in 2010, Brussels, Belgium in 2011 and Turin in Italy in 2013.

PROBLEM: Question: What is the difference between the two melanocortin receptors? Passage 1:The main party left England by sea on 20 January 1933, stopping at Gibraltar, where the Rock of Gibraltar "offered a climbing problem or two", and Aden. Time at sea was spent discussing the problem of climbing Mount Everest and the establishment of the various camps on its northern side, as well as learning the Nepali language, in which Crawford was proficient. The party alighted at Bombay, where they were assisted by C. E. Boreham, the manager of the Army and Navy Stores. Ruttledge, an India hand, took them on sightseeing tours to Agra and Fatehpur Sikri. Passing through Calcutta, where they were entertained by the Governor of Bengal, Sir John Anderson, the expedition members proceeded to Darjeeling, where Smythe, Greene and Birnie joined them, while Ruttledge went to Siliguri to rendezvous with Shebbeare and discuss transport arrangements. At Darjeeling porters were selected for the march, Ruttledge's Sherpas from his 1932 trip, Nima Dorje and Sanam Topgye, having gone to Sola Khombu to alert prospective applicants to the existence of the British expedition. Llakpar Chedi, Lewa and Nursang were selected as sirdars. In addition, Nima Tendrup, a veteran of many expeditions to Mount Everest, as well as a number of Sherpas who had been on the recent German expeditions to Kangchenjunga, were brought along. Karma Paul, who had been on the 1922 and 1924 British expeditions, was taken as interpreter. All the porters were screened at the Darjeeling hospital, 34 per cent being found to be infected with internal parasites, and then clothed in blue-and-white striped pyjamas and given numbered identity disks.
 Passage 2:AGRP has been demonstrated to be an inverse agonist of melanocortin receptors, to be specific MC3-R and MC4-R. The melanocortin receptors, MC3-R and MC4-R, are directly linked to metabolism and body weight control. These receptors are activated by the peptide hormone α-MSH (melanocyte-stimulating hormone) and antagonized by the agouti-related protein. Whereas α-MSH acts broadly on most members of the MCR family (with the exception of MC2-R), AGRP is highly specific for only MC3-R and MC4-R. This inverse agonism not only antagonizes the action of melanocortin agonists such as α-MSH but also further decreases the cAMP produced by the affected cells. The exact mechanism by which AgRP inhibits melanocortin-receptor signalling is not completely clear. It has been suggested that Agouti-related protein binds MSH receptors and acts as a competitive antagonist of ligand binding. Studies of Agouti protein in B16 melanoma cells supported this logic. The expression of AgRP in the adrenal gland is regulated by glucocorticoids. The protein blocks α-MSH-induced secretion of corticosterone.
 Passage 3:Carlito Guansing Galvez, Jr. is a retired Filipino general and the former Chief of Staff of the Armed Forces of the Philippines. He is a graduate of the Philippine Military Academy "Sandiwa" Class of 1985. He is also known for his leadership of the AFP Western Mindanao Command during the Battle of Marawi. He is a recipient of the United States Eisenhower Fellowships in 2006 and worked on the peace process with the Moro Islamic Liberation Front in 2015 as co-Chairman on the Coordinating Committee on the Cessation of Hostilities (CCCH). He also commanded the Army 104th Brigade, and the 6th Infantry Division. He,then an Army Lieutenant, along with some PMA 1985 classmates, including Rolando Joselito Bautista was also granted amnesty from Former AFP Chief and President Fidel Ramos, during the 1989 Coup.
