Q: Question: How many soldiers did Britain send to World War I the year Roebuck arrived on the Western Front? Passage:As a boy, Roebuck worked as a trammer and after being sentenced to one month's imprisonment for stealing a watch in 1904, he enlisted in the York and Lancaster Regiment. Over the next seven years, he was stationed in India and Ireland and was promoted to lance corporal, but was demoted back to private in 1910 for "misconduct". He married in 1908 and had two children. Roebuck was discharged into the reserves in 1912 and likely returned to work as a miner prior to becoming a professional footballer in 1913. After Britain's entry into the First World War in August 1914, he was called up by the York and Lancaster Regiment and arrived on the Western Front in September 1914. On 18 October 1914, Roebuck recorded as "presumed dead" after an attack near Beaucamps-Ligny during the Race to the Sea. His death was confirmed by two comrades in January 1915. Roebuck is commemorated on the Ploegsteert Memorial to the Missing.

Q: Question: How many total album sales were made between the 1978 Who album that Bundrick was invited to play on and the 1981 album that he was featured on?

Q: Question: How long has the Scottish Football Association been in existence when they delayed processing Cadete's registration? Passage:On 24 February 1996, Cadete was introduced at Celtic Park, Glasgow to supporters before Celtic's league match against Partick Thistle. However, due to lengthy negotiations between Celtic and Sporting and issues with registering the player, his transfer was not finalised until April, and turned out to be controversial: despite being signed prior to the transfer deadline, the Scottish Football Association delayed processing his registration in time for the Scottish Cup semi-finals against Rangers at Hampden Park, and following a complaint from Celtic chairman Fergus McCann, SFA chief Jim Farry was eventually relieved of his duties after being found guilty of deliberately holding back the player's registration. His eventual debut came at home against Aberdeen as he came off the bench to score his team's fifth goal in a 5–0 win, thus becoming an instant hit; the loud roar generated by the fans celebrating his goal blew out BBC Radio 5's microphones, who had been covering the game UK wide on radio, and they went off air for a short time until it was repaired.
