Q: Question: What city did Mathews work in for Wrestlemania XXVII? Passage:In late 2010, Mathews often worked as the color commentator on Raw due to Jerry Lawler's increased in-ring competition. On April 3, 2011, Mathews commentated the majority of WrestleMania XXVII, though he received a 'Stone Cold Stunner' from an angered Stone Cold Steve Austin, cutting his night short. The following night on Raw, Mathews found himself aligned with Jerry Lawler, and against Michael Cole. He then became the alternate spokesman for the Anonymous Raw General Manager, when Michael Cole was not commentating. He then using the new catchphrase "The Anonymous Raw General Manager says...", before reading each e-mail. On the April 25 episode of Raw, Mathews announced that the Jim Ross and Jerry Lawler vs. Michael Cole and Jack Swagger match at Extreme Rules will be a Country Whipping match, which Cole and Swagger won. At the following pay-per-view, Over the Limit, Mathews supported Lawler, Bret Hart and Eve Torres in having Michael Cole kiss Lawler's foot. The following night, again as the spokesman for the anonymous Raw General Manager, Mathews read the e-mail that denied The Miz's request for another title shot, seemingly done with John Cena. He left the Raw broadcasting table the following week, after Cole and Lawler reconciled, though he remained on the show as a backstage interviewer and backup commentator.

Q: Question: Did SFA chief Jim Farry work in football again after being relieved of his duties for holding back the player'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.
