Question: How many years had the station been on air when it switched its call sign to WGVC? Passage 1:The station became WQXL in 1962 after the station was sold to the Belk Broadcasting Company. The WOIC call sign resurfaced that same year on 1320 AM (now WISW). WQXL originally aired a Big Band format, which eventually gave way to a Top 40 format by the end of the decade. However it was handicapped with a daytime-only signal and was unsuccessful in competing against format rivals 1230 WNOK and 1400 WCOS, which each had full-time signals. Probably its most notable personality was Mackie "Cactus" Quave who had worked at 560 WIS (now WVOC) and had a successful kids TV show on NBC Network affiliate Channel 10 WIS-TV. WQXL switched to country music in the summer of 1966, but again was bested by rival 620 WCAY (now WGCV). In 1973, the station switched to religious programming and eventually adopted a Contemporary Christian format.
Passage 2:Dominguin was also a socialite, having friends like Pablo Picasso and romances with the American actress Ava Gardner and the fashion model China Machado. In 1955, he married actress Lucia Bose, who gave birth to his son Miguel Bose, a Grammy-award winning singer. He also occasionally appeared in films, predominantly playing himself in cameo roles, in movies such as Around the World in 80 Days (1956), Testament of Orpheus (1960), and The Picasso Summer (1969). In 1959, he and his brother-in-law, Antonio Ordonez, engaged in a bullfighting rivalry that was chronicled by Ernest Hemingway in his book, The Dangerous Summer. Ordonez won. In 1964 he was a mystery guest on the US TV show What's My Line?.
Passage 3:The ascot is descended from the earlier type of cravat widespread in the early 19th century, most notably during the age of Beau Brummell, made of heavily starched linen and elaborately tied around the neck. Later in the 1880s, amongst the upper-middle-class in Europe men began to wear a more loosely tied version for formal daytime events with daytime full dress in frock coats or with morning coats. It remains a feature of morning dress for weddings today. The Royal Ascot race meeting at the Ascot Racecourse gave the ascot its name, although such dress cravats were no longer worn with morning dress at the Royal Ascot races by the Edwardian era. The ascot was still commonly worn for business with morning dress in the late 19th and very early 20th centuries.

Passage 2:Casualty is a British medical drama television series that premiered on 6 September 1986 on BBC One. The series was created by Jeremy Brock and Paul Unwin. It is set in the fictional Holby City Hospital, in the equally fictitious city of Holby, and features occasional crossovers of characters and plots with spin-off show Holby City. Casualty follows the professional and personal lives of the doctors, nurses, paramedics, hospital management and patients at Holby General. It features an ensemble cast of regular characters, and began with 10 main characters in its first series, all but two Charlie Fairhead (played by Derek Thompson) and Lisa "Duffy" Duffin (played by Cathy Shipton) have since left the show. Many main characters have been written in and out of the series since. In addition, Casualty features guest stars each week, as well as recurring guests that take part in story arcs that span a portion of a series or multiple series.
Passage 3:Anna Kraus, Op. 30 is a radio opera in one act by composer Franz Reizenstein. The work uses an English language libretto by Christopher Hassall to tell the tragic tale of a German woman who is forced to leave her country due to oppression from the Nazi regime, as the Nazis did not like her political views. The opera was commissioned by the British Broadcasting Corporation following the popular success of Reizenstein's 1951 cantata Voices of Night. The opera premiered on 25 July 1952 on BBC Third Programme with conductor Norman Del Mar leading the BBC Symphony Orchestra and singers Victoria Sladen (as Anna) and Lloyd Strauss-Smith (as Pavel). It was submitted by the BBC later that year for the Prix Italia. Critical reaction to the work was mixed. The New Statesman described the work as "engaging" and a "worthwhile experiment". The Annual Register wrote that the opera "suffered from the composer's emotion being too closely engaged in the sufferings of the heroine, a refugee from political oppression".

Question: Where was Herz' teacher born? Passage 1:From 1916 to 1922, Thomson served on the Seattle city council, while continuing to work as a civil engineer. After leaving the council, he continued working various places in the Pacific Northwest and Alaska. He consulted on Oregon's Rogue River Valley Irrigation Canal; built hydroelectric plants in Eugene, Oregon and surveyed plant sites in Southeastern Alaska; planned the water supply of Bellingham, Washington and consulted on the system for Wenatchee; briefly, in his seventies, he returned, temporarily, as Seattle city engineer in 1930 to finish the Diablo Dam on the Skagit River after the death of city engineer William D.

Passage 2:The Complete Compleat Enchanter is an omnibus collection of five fantasy stories by Ametican authors L. Sprague de Camp and Fletcher Pratt, gathering material previously published in three volumes as The Incomplete Enchanter (1941), The Castle of Iron (1950), and Wall of Serpents (1960), and represents an expansion of the earlier omnibus The Compleat Enchanter, which contained only the material in the first two volumes. The expanded version also differs from the previous omnibus by omitting its afterword, de Camp's essay "Fletcher and I". The omnibus is the first edition of the authors' Harold Shea series to be complete in one volume. It has appeared under three different titles. It was first published in the UK in paperback by Sphere Books in 1988 under the title The Intrepid Enchanter and with a foreword by Catherine Crook de Camp. The first US edition appeared under the title The Complete Compleat Enchanter, and replaces the foreword with a preface by David Drake. That edition was published by Baen Books in 1989, and has been reprinted a number of times since. Orion Books published an edition in the UK under the title The Compleat Enchanter in 2000 as volume 10 of their Fantasy Masterworks series. The stories in the collection were originally published in magazine form in the May 1940, August 1940 and April 1941 issues of Unknown, the June 1953 issue of Beyond Fantasy, and the October 1954 issue of Fantasy.
Passage 3:Born in Berlin to very poor parents, Herz was destined for a mercantile career, and in 1762 went to Konigsberg, East Prussia. He soon gave up his position as clerk and attended the University of Konigsberg, becoming a pupil of Immanuel Kant, but was obliged to discontinue his studies for want of means. He thereupon became secretary to the wealthy Russian Ephraim, traveling with him through the Baltic Provinces. On August 21, 1770, he traveled from Berlin and acted as respondent when Kant presented his Inaugural dissertation at the University of Konigsberg for the post of ordinary professor. In 1770 he had returned to Germany and studied medicine in Halle, where he became an MD in 1774, in which year he established himself in Berlin, being appointed physician at the Jewish hospital. Beginning in 1777, he delivered public lectures on medicine and philosophy, which were well attended by the students and the principal personages of the Prussian capital. At some of them even members of the royal family were present.
