Example Input: Question: What year did the newspaper who called Krul an excellent reserve goalkeeper first found? Passage:Krul returned to Newcastle as backup to first choice Steve Harper. He made his senior league debut on 8 August 2009 in the opening Football League Championship game of the season away to West Bromwich Albion, coming on as a half time substitute for the injured Harper.

He later played the full Football League Cup match against Huddersfield Town on 26 August 2009, which Newcastle won 43. Krul also started the 20 League Cup defeat to Peterborough. Against Swansea City on 28 November, he again came on to replace the injured Steve Harper. On 2 January, he played in the FA Cup Third Round tie against Plymouth Argyle, the game ending 00. He then played in the replay at St James' Park on 13 January, a 30 victory.

Example Input: Question: Did the Michigan coach that retired after 2007 or his successor have a better overall win-loss record at the school? Passage:Fred Jackson (born June 9, 1950) is an American football coach and former player. He was previously the running backs coach at the University of Michigan. In 2014, he was the longest tenured member of the Michigan Wolverines football coaching staff, having been with the program since 1992. Jackson served on the staffs of Gary Moeller, Lloyd Carr, Rich Rodriguez, and Brady Hoke. In addition to coaching running backs, Jackson served as Michigan's offensive coordinator (19951996), assistant head coach (19972002), and associate head coach (20032007). He was a finalist for the Broyles Award, given annually to the nation's top college football assistant coach, in 2000. After Michigan head coach Lloyd Carr retired following the 2007 season, Jackson was the only member of the coaching staff retained by Carr's successor, Rich Rodriguez. When Rodriguez was fired after the 2010 season, Jackson was the only member of Rodriguez's staff retained by his successor, Brady Hoke. Hoke and Jackson served as assistants together under Carr and Gary Moeller for a total of eight years including the 1997 national championship season.

Example Input: Question: Who owns the network that took footage of a flood staircase? Passage:The Ritz Carlton, Westin Peachtree Plaza, Georgia-Pacific Building, SunTrust Plaza (where more than 60 people had to be relocated out of their offices), Equitable Building, and Georgia State University also had windows blown out (300 at Equitable alone), as did The Tabernacle (a former church with stained glass that is now a concert venue). The windows of the Westin continued to fall for days after the tornado, forcing police to keep several city blocks and MARTA's Peachtree Center station closed to pedestrians. The Georgia World Congress Center also sustained flooding while hosting a JROTC event and the Hinman Dental Meeting; Fox Sports Net took footage of a staircase in the new section of the complex that looked like a fountain with water cascading down it. The annual Atlanta Home Show and all other events were cancelled for the weekend in the GWCC complex, as was the Atlanta St. Patrick's Day Parade scheduled for the next day. WRAS FM at Georgia State University was off the air for two days, though it was not stated whether its studio or tower sustained damage, or if this was due to security or safety concerns, or power outages. The historic Rialto Theatre at GSU also sustained roof damage, which caused water damage inside.
