Question: Is Prague the capital of a country? Passage:In the months following up to the September 11 attacks, officials at the Czech Interior Ministry asserted that Atta made a trip to Prague on April 8, 2001, to meet with an Iraqi intelligence agent named Ahmed Khalil Ibrahim Samir al-Ani. This piece of information was passed on to the FBI as "unevaluated raw intelligence". Intelligence officials have concluded that such a meeting did not occur. A Pakistani businessman named Mohammed Atta had come to Prague from Saudi Arabia on May 31, 2000, with this second Atta possibly contributing to confusion. The Egyptian Mohamed Atta arrived at the Florenc bus terminal in Prague, from Germany, on June 2, 2000. He left Prague the next day, flying on Czech Airlines to Newark, New Jersey, U.S. In the Czech Republic, some intelligence officials say the source of the purported meeting was an Arab informant who approached the Czech intelligence service with his sighting of Atta only after Atta's photograph had appeared in newspapers all over the world. United States and Czech intelligence officials have since concluded that the person seen with Ani was mistakenly identified as Atta, and the consensus of investigators has concluded that Atta never attended a meeting in Prague.

Question: When was the team Tuqiri last played for founded? Passage:Lote Daulako Tuqiri (born 23 September 1979) is a Fijian-Australian former professional dual-code rugby footballer who last played for the South Sydney Rabbitohs in the NRL. He represented Australia in both rugby league and rugby union, and Fiji in rugby league. He usually played as a winger in both codes. Tuqiri first rose to prominence as a professional rugby league footballer for the Brisbane Broncos and Queensland Maroons, as well as the Fiji and Australia national sides. He was therefore a high-profile signing for rugby union in 2002, winning 67 caps for Australia and being a part of their 2003 and 2007 World Cup squads. He played rugby union for the Waratahs in the Super 14 and Leicester Tigers in England in season 2009–10. Tuqiri's contract with the Australian Rugby Union was terminated on 1 July 2009. No immediate reason was given, and Tuqiri returned to rugby league in 2010, playing for the Wests Tigers of the NRL. In September 2013, he signed a short-term contract with Irish rugby union giants, Leinster to play in the Pro12 in a three-month deal. Just 6 weeks out from the 2014 NRL season, Tuqiri signed with his third NRL club, the South Sydney Rabbitohs on a one-year deal.

Question: How many years did the legendary king that created the Dal Riata rule for? Passage:Dál Riata is said to have been founded by the legendary king Fergus Mór (Fergus the Great) in the 5th century. The kingdom reached its height under Áedán mac Gabráin (). During his reign Dál Riata's power and influence grew; it carried out naval expeditions to Orkney and the Isle of Man, and assaults on the Brittonic kingdom of Strathclyde and Anglian kingdom of Bernicia. However, King Æthelfrith of Bernicia checked its growth at the Battle of Degsastan in 603. Serious defeats in Ireland and Scotland during the reign of Domnall Brecc (died 642) ended Dál Riata's "golden age", and the kingdom became a client of Northumbria for a time. In the 730s the Pictish king Óengus I led campaigns against Dál Riata and brought it under Pictish overlordship by 741. There is disagreement over the fate of the kingdom from the late 8th century onwards. Some scholars have seen no revival of Dál Riatan power after the long period of foreign domination ( to ), while others have seen a revival under Áed Find (736–778). Some even claim that the Dál Riata usurped the kingship of Fortriu. From 795 onward there were sporadic Viking raids in Dál Riata. In the following century, there may have been a merger of the Dál Riatan and Pictish crowns. Some sources say Cináed mac Ailpín (Kenneth MacAlpin) was king of Dál Riata before becoming king of the Picts in 843, following a disastrous defeat of the Picts by Vikings. The kingdom's independence ended sometime after, as it merged with Pictland to form the Kingdom of Alba.
