Question: Who was the ruler of South African mandate when it took over the South West Africa German colony? Passage 1:German Namibians () are a community of people descended from ethnic German colonists who settled in present-day Namibia. In 1883, the German trader Adolf Luderitz bought what would become the southern coast of Namibia from Josef Frederiks II, a chief of the local Oorlam people, and founded the city of Luderitz. The German government, eager to gain overseas possessions, annexed the territory soon after, proclaiming it German South West Africa (). Small numbers of Germans subsequently immigrated there, many coming as soldiers (), traders, diamond miners, or colonial officials. In 1915, during the course of World War I, Germany lost its colonial possessions, including South West Africa (see History of Namibia); after the war, the former German colony was administered as a South African mandate. The German settlers were allowed to remain and, until independence in 1990, German remained an official language of the territory alongside Afrikaans and English.
Passage 2:Earle L. Reynolds (October 18, 1910 January 11, 1998) was an anthropologist, educator, author, Quaker, and peace activist. He was sent to Hiroshima by the Atomic Energy Commission in 1951 to study the effects of the first atomic bomb on the growth and development of exposed children. His professional discoveries concerning the dangers of radiation later moved Reynolds into a life of anti-nuclear activism. In 1958 he sailed with his wife Barbara, two of his three children and a Japanese yachtsman in the Phoenix of Hiroshima, a ketch he had designed himself, into the American nuclear testing zone in the Pacific. In 1961 the family sailed to the USSR to protest Soviet nuclear testing. During the Vietnam War Reynolds and his second wife Akie sailed the Phoenix to Haiphong to deliver humanitarian and medical aid to victims of American bombing.
Passage 3:The Anita Kerr Singers or The Jordanaires sang background on just about every Nashville hit in the late 1950s and early 1960s. After she and Al Kerr divorced, she disbanded the Nashville version of her Anita Kerr Singers and relocated to Los Angeles in August 1965 with her second husband, Swiss businessman Alex Grob, and her daughters Suzie & Kelly. She no longer wanted to just be a background singer or arranger on country songs she wanted to do pop music, jazz and "do more orchestral writing and music that was not just country.". She hired some lawyers to get her out of her contract with RCA's Nashville division, got a contract with Warner Bros. Records, and formed a Los Angeles version of the Anita Kerr Singers. The new group, for the next five years, would include the following personnel: alto B.J. Baker or Jackie Ward, tenor Gene Merlino or Bill Cole, baritone Bill Lee, bass Bob Tebow, and Kerr herself as soprano and arranger. The half dozen albums recorded by the Singers for Warner included a cover version of the song "All You Need Is Love" by The Beatles, and one of the LPs was exclusively devoted to the songs of composer Bert Kaempfert. Disguising the group as the Mexicali Singers, Kerr also recorded a trio of mariachi-flavored albums with musical arrangements reminiscent of the Herb Alpert & The Tijuana Brass sound. The Anita Kerr Singers won another Grammy Award for their recording of A Man And A Woman, released as a single on Warner Bros. Records.

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 197879, 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 198889, 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 2:Robbins has been honored by many bands, including the Grateful Dead who covered "El Paso" and Bob Weir & Kingfish who covered "Big Iron". The Who's 2006 album Endless Wire includes the song "God Speaks of Marty Robbins". The song's composer, Pete Townshend, explained that the song is about God deciding to create the universe just so he can hear some music, "and most of all, one of his best creations, Marty Robbins." The Beasts of Bourbon released a song called "The Day Marty Robbins Died" on their 1984 debut album The Axeman's Jazz. Both Frankie Laine and Elvis Presley, among others, recorded versions of Robbins' song "You Gave Me a Mountain", with Laine's recording reaching the pop and adult contemporary charts in 1969. Though Elvis never recorded any of Robbins' songs in the studio, he was a big fan and recorded "You Gave Me a Mountain" live in concert several times; it appeared on 15 Presley albums. Johnny Cash recorded a version of "Big Iron" as part of his American Recordings series, which is included in the Cash Unearthed box set. Cash also recorded other songs by Robbins, including "I Couldn't Keep From Crying", "Kate" and "Song Of The Patriot". He held Robbins in high esteem, having him guest several times on his network TV show. "Big Iron" was also covered by Mike Ness on his album Under the Influences, on which he paid homage to country music artists. The song, originally released on Robbins' 1959 album Gunfighter Ballads and Trail Songs, gained renewed popularity following its use in the video game .
Passage 3:In the spring of 1902, Bulgaria, an Ottoman vassal state which was interested in acquiring Macedonia, signed a military convention with Russia. Late in the fall, Russia, supported by the United Kingdom and France, proposed to the Ottomans political reforms for the Macedonian vilayets. On 8 December, the Ottoman sultan, Abdul Hamid II, signed a decree implementing most of the reforms. In February 1903, the new Russian foreign minister, Vladimir Lamsdorf, visited Vienna and signed the so-called "Vienna Program" on Macedonian reforms. The program was substantially the same as the Ottoman decree of December. The immediate provocation of a new agreement at Murzsteg was the IlindenPreobrazhenie Uprising that broke out on 2 August. With its quick suppression, the Vienna Program lay dead. In September Tsar Nicholas II of Russia visited the Emperor Francis Joseph of Austria-Hungary at the latter's castle in Murzsteg, Austria. The two rulers put their signatures to a new memorandum, substantially identical to the Vienna Program, which called for the appointment of one Russian and one Austro-Hungarian civil agent to oversee the reform of the administration, judiciary and local gendarmerie in the Macedonian vilayets. In all these institutions Christians were to take part. After Abdul Hamid accepted the proposal in November, Russia appointed one N. Demerik as its agent, and Austria chose one G. Muller. They began their work under Huseyin Hilmi Pasha, the Inspector-General of Macedonia, in early 1904. Under the Murzsteg program, each Great Power appointed an advisory official to the Ottoman official in charge of reforming the gendarmerie in each province. Austria-Hungary appointed an advisor to the sanjak of Uskup, Russia to the sanjak of Thessaloniki, France to the sanjak of Siroz and Britain to the sanjak of Drama.
