Example Input: Question: How many games were won in the 2009 CECAFA Cup by the team that Eritrea beat 3-1? Passage:Eritrea returned to the 2009 CECAFA Cup in Nairobi. A young squad was assembled with just 12 days' training. In Group B, they gained a surprise draw with Zimbabwe, lost narrowly to Rwanda, and beat Somalia 3–1. They were easily beaten 4–0 in the quarter-finals by Tanzania. Twelve squad members failed to report for the return flight, and sought the assistance of the Refugee Consortium of Kenya. They were believed to be in hiding in Eastleigh, an eastern suburb of Nairobi home to many immigrants. Nicholas Musonye, the secretary-general of CECAFA, feared that the government might react by refusing to let the team travel abroad in future. The twelve players were later granted interim asylum by the United Nations High Commissioner for Refugees in Kenya. Eleven of these players have since travelled to Adelaide in Australia with two of them, Samuel Ghebrehiwet and Ambes Sium, signing for Gold Coast United in the A-League in August 2011.

Example Input: Question: Have Liverpool or Chelsea won more titles? Passage:Arsenal had finished the previous season as runners-up in the Premier League, overhauled by Manchester United in the final ten weeks of the season. The club did, however, retain the FA Cup, with a 1–0 win against Southampton. Such was Arsenal's effective start to the 2002–03 campaign, manager Arsène Wenger suggested his team could remain the whole season undefeated in all competitions:It's not impossible as A.C. Milan once did it but I can't see why it's so shocking to say it. Do you think Manchester United, Liverpool or Chelsea don't dream that as well? They're exactly the same. They just don't say it because they're scared to look ridiculous, but nobody is ridiculous in this job as we know anything can happen. The team lost to Everton a month after Wenger's proclamation; teenager Wayne Rooney scored the match winner, which ended a run of 30 league games without defeat. By February 2003, Arsenal moved five points clear of Manchester United at the top of the league table, but injuries to key players, not least captain Patrick Vieira, had destabilised the team. Draws in April, coupled with a defeat to Leeds United at home, mathematically ended Arsenal's chances of retaining the title. Wenger refuted opinions from the media that their season was a failure and said:

Example Input: Question: How long had Crewe Alexandra been a club when Luton Town F.C. defeated them 6-0? Passage:Luton began the season at home to Yeovil Town and won the match 8–2, the club's biggest Football League victory since a 6–0 win over Crewe Alexandra in December 1996. Otis Khan gave the away team the lead in the seventh minute with a free kick from 22 yards, before Olly Lee equalised five minutes later with a volley from Isaac Vassell's cross. James Collins put Luton in front on 19 minutes when he chipped the ball over goalkeeper Artur Krysiak and into the net, before Alan McCormack scored with a volley from 25 yards five minutes later to make the score 3–1. Vassell then scored twice in two minutes to give Luton a 5–1 lead, before Marek Štěch saved a penalty from Khan to ensure the score remained the same going into half-time. Collins scored twice in eight minutes after half-time to complete his hat-trick, before François Zoko scored a consolation goal for Yeovil a minute later with a header from Ryan Dickson's cross, and Elliot Lee scored Luton's eighth goal in the ninth minute of stoppage time. Transfer-listed midfielder Jonathan Smith had his contract with Luton terminated by mutual consent, allowing him to join Stevenage, while forward Harry Cornick was signed from Bournemouth on a two-year contract, with the option of a one-year extension, for an undisclosed fee. Luton were knocked out of the EFL Cup in the first round after being beaten 2–0 at home to Championship club Ipswich Town, who scored in each half through David McGoldrick. Frankie Musonda signed a new contract with Luton, which contracted him to the club until the summer of 2019, and Kavan Cotter joined Southern League Premier Division club Hitchin Town on a one-month youth loan. Luton suffered their first league defeat of the season after losing 1–0 to Barnet, who scored in second-half stoppage time through Jack Taylor with a 25-yard curling shot. Vassell joined Championship club Birmingham City for an undisclosed fee.
