Question: How old was Reynolds when the last US forces withdrew from Vietnam? Passage 1: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 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:Charles K. Carpenter (born in 1872 in Illinois, died in 1948) was a prominent minister in northern Illinois and a charter member of the Illinois State Academy of Science. During his years of service as a minister, his avocation was recording observations of nature and preparing study skins and life mounts of animals of the region. After his retirement from the church in 1940, he organized his collections and observations into the Northern Illinois Museum of Natural History, which he maintained at his home in Baileyville, Ogle County, Illinois. After his death in 1948, most of his life mounts were given to a high school, where they remained until 1983 when they were donated to the Illinois State Museum. Many of his bird study skins, egg sets, and photographs were given to Cornell College in Mount Vernon, Iowa; in 1985-1986 these were transferred to the Illinois State Museum. Among his specimens was a life mount of a (now extinct) passenger pigeon, Ectopistes migratorius (Linnaeus, 1766), collected by his father, Edwin A. Carpenter (born in 1846 in Pennsylvania, died in 1919 in Illinois). This specimen is one of only 19 complete and 7 partial skeleton specimens of passenger pigeons known to exist in museum collections.
