Question: What state was the president who appointed Nelson to the President's Export Council from? Passage:In 1967 at the start of the governorship of Ronald Reagan one of Reagan's first actions was to fire Nelson from her state government post at the Consumer Counsel. Nelson said that this was because she was disliked by Reagan's supporters, including the California Grocer's Association and the California Manufacturers' Association. After this she became elected president of the Consumer Federation of California. She served also on the board of Consumers Union, and would be re-elected for a total of five three-year terms on that board. From 1969-1979 served as a professor of economics at the University of Wisconsin. During this time she also served as a public governor for the American Stock Exchange. In 1968 after 15 years of work her lobbying had contributed to the passing of the Truth in Lending Act. She served two terms as president of the Consumer Federation of America from 1972-1982. She was the consumer consultant to the Office of Technology Assessment and the National Academy of Science. She petitioned the National Academy of Science to recognize the research showing saccharin as a cancer-causing agent and fluorocarbons as causing ozone depletion. In 1978 President Jimmy Carter appointed Nelson to the President's Export Council. Also in 1978 the American Council on Consumer Interests recognized her as a "Distinguished Fellow". In 1979 after the 1977 death of her husband Nelson returned to Mill Valley, California. There she was appointed to the Consumer Advisory Council of the Federal Reserve Board of Governors, the consumer advisory panel for Pacific Bell, and the San Francisco chapter of Consumer Action. At this time she said that her worst fear for the future was "That consumers will become like the feudal people of old times. That they will be so tied to a VISA card that they are not whole people. That they will be easily manipulated by the television and sellers, that they will do what is suggested to them instead of what comes from their own spirit."

Question: When was Ōe Tokihiro's father born? Passage:The first castle on this site dates to the middle of the Kamakura period. Ōe Tokihiro, the younger son of Ōe no Hiromoto, a senior retainer of the Kamakura shogunate was granted lands in Dewa Province, and in 1238 changed his name to Nagai Tokihiro. The Nagai continued to rule for about 150 years. The Nagai were supplanted in the Sengoku period by the Date clan, and the famed warlord Date Masamune was born at Yonezawa Castle. After Date Masamune defeated the Ashina clan in 1589, he moved his main castle to Kurokawa Castle in Aizu and put Date Munekiyo in charge of Yonezawa. However, Toyotomi Hideyoshi did not agree, and forced Masamune move back to Yonezawa. In 1591, Masamune relocated to Iwadeyama Castle by orders of Hideyoshi, surrendering Yonezawa Castle to Gamō Ujisato. When Ujisato’s son, Gamō Hideyuki was moved to Utsunomiya in 1597, the castle was turned over to Uesugi Kagekatsu, as part of their vast 1,200,000 koku holdings based in Aizu. The castellan at this time was Naoe Kanetsugu.

Question: Did Alberto Randegger and Richard Mansfield have any collaborative works together? Passage:After leaving the Academy, German continued to teach at Wimbledon School and to play the violin in orchestras at various London theatres, including the Savoy. In 1888, an introduction by conductor Alberto Randegger to theatre manager Richard Mansfield led to German's appointment as conductor and musical director at the Globe Theatre in London. There he improved the orchestra and began providing incidental music for the theatre's lavish productions, starting with Richard III in 1889. This music was well received (The Times called for a concert suite to be arranged), and the overture soon became popular in concert halls. This eventually led to other incidental music commissions that gained success. In 1892, German composed music for a production of Henry Irving's version of Henry VIII at the Lyceum Theatre, London, where he incorporated elements of traditional old English dance. Within a year, sheet music of the dance numbers from the play's score had sold 30,000 copies. German was by then in great demand to write music for plays. His commissions included Henry Arthur Jones's The Tempter in 1893, Johnston Forbes-Robertson's Romeo and Juliet at the Lyceum in 1895, Herbert Beerbohm Tree's productions of As You Like It (1896) and Much Ado about Nothing (1898), and Anthony Hope's English Nell (later known as Nell Gwynn) in 1900, starring Marie Tempest.
