Q: Passage: Francis recorded works of Francis Poulenc, symphonies and symphonic works of Otto Klemperer with the Staatsphilharmonie Rheinland-Pfalz, and symphonies of Allan Pettersson with different orchestras, among others. In 1980 he recorded Offenbach's operetta Robinson Crusoé with the Royal Philharmonic Orchestra. In 2000 he was awarded the first prize of the Cannes Classical Award in the category CD premiere for his recording of the complete symphonies of Darius Milhaud with the Sinfonieorchester Basel. He conducted a recording of Carl Reinecke's four piano concertos with pianist Klaus Hellwig and the Nordwestdeutsche Philharmonie. He is the only conductor to have recorded – with the BBC Scottish Symphony Orchestra for the CPO label – all five symphonies by the English composer Humphrey Searle.
 Link Information: Searle was the son of Humphrey and Charlotte Searle and, through his mother, a grandson of Sir William Schlich. He was born in Oxford where he was a classics scholar before studying—somewhat hesitantly—with John Ireland at the Royal College of Music in London, after which he went to Vienna on a six-month scholarship to become a private pupil of Anton Webern, which became decisive in his composition career. Answer: Oxford

A: Where was the composer of five symphonies educated?

Q: Passage: He was a founder of the St. Louis Art Museum and the State Historical Society of Missouri, president of the St. Louis Public Library, and a director of the St. Louis World's Fair (Louisiana Purchase Exposition) of 1904, in which he was host of the Universal Congress of Jurists and Lawyers. He was a bibliophile and he collected rare first editions of Charles Dickens, Robert Burns and others, and artworks of Aubrey Beardsley, George Cruikshank and Thomas Rowlandson. He and industrialist William K. Bixby started the Burns Society; he was twice president of the University Club of St. Louis. He had a remarkable (possibly eidetic) memory—when writer Henry James visited his house, Lehmann could recite whole works that James himself had written but forgotten. For most his life Lehmann was in demand as a public speaker, which he thoroughly enjoyed. His published works included: John Marshall (1901); The Lawyer in American History (1906); Abraham Lincoln (1908); Conservatism in Legal Procedure (1909); Prohibition (1910); and The Law and the Newspaper (1917).
 Link Information: from April 30 to December 1, 1904 Answer: 216

A: How many days did the fair that Lehmann hosted in 1904 last?

Q: Passage: In 1809, Walter Coffin sunk the first coal pit in the Rhondda, further up the valley in Dinas, but a lack of a transportation network greatly affected the profitability of coal mining as an industry in the region. Coffin tackled this problem by constructing a one-mile tramline which connected his mines in Dinas to a tramline built by Dr. Richard Griffiths at Denia (Pontypridd), which linked to a private canal that joined onto the Glamorganshire Canal at Treforest. Coffins tramline followed the southern bank of the River Rhondda and ran through Porth. The existence of the tramline made the development of the Porth and Cymmer region far more attractive, and by the middle of the 19th century there was an impetus to expand coal mining in the area. In 1841 Richard Lewis joined Coffin in trying to exploit the region with his level built at Cymmer. This resulted in the construction of around fifty miners' cottages, several of which were located in Porth. In 1844 Lewis Edwards of Newport and George Gethin of Penygraig opened a small level at Nyth-bran on the eastern borders of Porth, the villages' first coal mine. This was followed in 1845 by the sinking of the Porth Colliery by David James of Merthyr, the success of which saw him build the Llwyncelyn Colliery in 1951, also in Porth. By 1850 the Taff Vale Railway had been extended to Cymmer replacing the tramline, allowing direct access between the lower Rhondda and the ports of Cardiff.
 Link Information: It was opened in stages in 1840 and 1841. Answer: 10

A:
How long had the Taff Vale Railway been in existence the year it was extended to Cymmer?
