Question: What was the name of Yes first two albums? Passage:Hot on the heels of the huge success of CSNY and Led Zeppelin, British band Yes rapidly established themselves as one of the leading groups in the burgeoning progressive rock genre, and their success also played a significant part in establishing the primacy of the long-playing album as the major sales format for rock music in the 1970s. After several lineup changes during 1969–70, the band settled into its "classic" incarnation, with guitarist Steve Howe and keyboard player Rick Wakeman, who both joined during 1971. Although the extended length of much of their material made it somewhat difficult to promote the band with single releases, their live prowess gained them an avid following and their albums were hugely successful – their third LP The Yes Album (1971), which featured the debut of new guitarist Steve Howe, became their first big hit, reaching #4 in the UK and just scraping onto the chart in the US at #40. From this point, and notwithstanding the impact of the punk/new wave movement in the late 1970s, the band enjoyed an extraordinary run of success—beginning with their fourth album Fragile, each of the eleven albums they released between 1971 and 1991 (including the lavishly packaged live triple-album Yessongs) made the Top 20 in the US and the UK, and the double-LP Tales of Topographic Oceans (1973) and Going For The One (1977) both reached #1 in the UK.

Question: How long was Robert in the Parliament? Passage:Richard Bennet (d.1619), a Councillor at Law, built Hexworthy House as his seat within the parish. The Bennet family originated in Sussex and settled at Hexworthy during the reign of Queen Elizabeth I (1558-1603). His son was Col. Robert Bennet (1605–1683) of Hexworthy, a Member of Parliament during the Civil War and a noted commander of the Parliamentarian forces. His descendant Richard Bennett-Coffin (d.1796) was the son of Edward Bennett of Lawhitton by his wife Honor Coffin (born 1682), 11th daughter of Richard Coffin (1623-1700) of Portledge in the parish of Alwington in North Devon, lord of the manor of Alwington and Sheriff of Devon in 1683. Richard Bennett-Coffin (d.1796) became heir to the Coffin estates following the death of his childless uncle Richard Coffin (1684-1766). The Coffin family had been established at Alwington since the reign of King Henry II (1154-1189), and remained there in unbroken male succession until 1766. He adopted the name and arms of Coffin, but died without progeny at Esher in Surrey and was buried at Lawhitton where survives his monument. His heir was Rev. John Pine-Coffin (1735-1824), eldest surviving grandson of Dorothy Coffin (1651-1690), eldest daughter of Richard Coffin (1623-1700), who in 1672 married Edward Pyne (1648-1675) of East Down. Her descendants remained seated at East Down manor house until 1866, the Pyne family having occupied it since the 13th century. The last in the Pine-Coffin family to occupy Portledge manor house was Richard Geoffrey Pine-Coffin (1908-1974).

Question: How long did the Kingdom of Bavaria remain independent after the Congress of Vienna? Passage:During the French Revolution and Napoleonic times, Horschbach lay within the Department of Mont-Tonnerre (or Donnersberg in German), whose seat was at Mainz, the Canton of Wolfstein and the Arrondissement of Kaiserslautern. After French rule ended and Napoleon met his ultimate political fate at Waterloo, the Congress of Vienna awarded a great swathe of territory in this region to the Kingdom of Bavaria, and by 1817, Horschbach found itself within this exclave, called the Bayerischer Rheinkreis (“Bavarian Rhine District”). More locally, it lay within the Landcommissariat (later Bezirksamt, later still Landkreis or district) of Kusel and the Canton of Wolfstein. Horschbach was also an administrative seat, home to the Bürgermeisterei (“mayoralty”) for the three Herrmannsberg municipalities of Horschbach, Elzweiler and Welchweiler, and from the beginning until 1838 also for Bedesbach, a village on the river Glan. Such was the uniting force of this arrangement that until 1853, the villages of Horschbach and Elzweiler were regarded as one village. In 1923, the warriors’ memorial for those who fell in the First World War was built. The following year, electric lighting was installed in Horschbach. At elections between 1920 and 1933 – in Weimar times – the strongest showings were among centre-right and rightwing parties, a common pattern in places with a strongly developed agricultural structure. Indeed, in the late 1920s and early 1930s, the Nazi Party (NSDAP) became quite popular in Horschbach. In the 1928 Reichstag elections, none of the local votes went to Adolf Hitler’s party, but by the 1930 Reichstag elections, this had grown to 23.9%. By the time of the 1933 Reichstag elections, after Hitler had already seized power, local support for the Nazis had swollen to 92.5%. Hitler’s success in these elections paved the way for his Enabling Act of 1933 (Ermächtigungsgesetz), thus starting the Third Reich in earnest. It was not until 1949 that the first tractor, owned by a man named Ernst Mäurer, made its appearance in Horschbach. Bavarian times ended with the Allied occupation after the Second World War and the region became part of the then newly founded state of Rhineland-Palatinate. The Bürgermeisterei of Horschbach, however, remained in force until 1968, when there was sweeping administrative restructuring in Rhineland-Palatinate. Horschbach then lost its administrative function, and since 1972 it has been an Ortsgemeinde within the Verbandsgemeinde of Altenglan. In 1956, a third schoolhouse was built. Like the first one, it is now used as a house. In 1968, 23 years after the war ended, the warriors’ memorial for those who fell in the Second World War was built. That same year, the church got a new organ. In a turnaround from what was the pattern in Weimar times, left-leaning parties now do somewhat better in local elections, if not as strongly as in the other Herrmannsberg municipalities of Elzweiler and Welchweiler. In 1972, the “Mühlgärten und Steinbach” building plan was set forth. In 1973, Horschbach came in second at the district level in the contest Unser Dorf soll schöner werden (“Our village should become lovelier”), and the renovated church (new pews and heating) became ready for use. Modern sewerage was laid in 1975. In 1976 came the last day of school. The local primary school was closed on 28 July, as the ones in Elzweiler (27 June 1973) and Welchweiler (30 November 1966) already had been. The schoolchildren thereafter had to go to school in Rammelsbach. Another building plan was set forth in 1998, “Am Hofacker”. A linking street was built to the site the following year. In 2009, a photovoltaic array was installed on the former schoolhouse's roof.
