[EX Q]: 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.

Passage 3:About this time, some Dzungars informed the Kangxi Emperor that the 5th Dalai Lama had long since died. He sent envoys to Lhasa to inquire. This prompted Sangye Gyatso to make Tsangyang Gyatso the 6th Dalai Lama public. He was enthroned in 1697. Tsangyang Gyatso enjoyed a lifestyle that included drinking, the company of women, and writing love songs. In 1702, he refused to take the vows of a Buddhist monk. The regent, under pressure from the Emperor and Lhazang Khan of the Khoshut, resigned in 1703. In 1705, Lhazang Khan used the sixth Dalai Lama's escapades as excuse to take control of Lhasa. The regent Sanggye Gyatso, who had allied himself with the Dzungar Khanate, was murdered, and the Dalai Lama was sent to Beijing. He died on the way, near Kokonor, ostensibly from illness but leaving lingering suspicions of foul play. Lhazang Khan appointed a new Dalai Lama who, however, was not accepted by the Gelugpa school. Kelzang Gyatso was discovered near Kokonor and became a rival candidate. Three Gelug abbots of the Lhasa area appealed to the Dzungar Khanate, which invaded Tibet in 1717, deposed Lhazang Khan's pretender to the position of Dalai Lama, and killed Lhazang Khan and his entire family. The Dzungars proceeded to loot, rape and kill throughout Lhasa and its environs. They also destroyed a small force in the Battle of the Salween River which the Emperor had sent to clear traditional trade routes.
