Question: What is the capacity of Derby's Pride Park stadium? Passage:As a result of Hull finishing in fourth place in the Championship they qualified for the Football League play-offs. In the play-off semi finals Hull played against fifth placed team Derby County over two legs. The first leg was held on 14 May 2016 at Derby's Pride Park. Hull's top scorer Abel Hernandez was the first to score with a strike from 25 yards after half an hour. This was followed 10 minutes later with a shot by Moses Odubajo deflected in by defender Jason Shackell. Andrew Robertson completed the scoring with a late stoppage time goal to give Hull a 30 advantage going into the second leg at the KC Stadium on 17 May 2016. Derby got off to a great start with a goal from close range by Johnny Russell after 7 minutes. Their lead was doubled when a sliced ball by Andrew Robertson went into his own net 30 minutes later. Derby continued to press but Hull hung on to deny them any further scores. The match ended 20 to Derby, but Hull progressed 32 on aggregate, much to the relief of manager Steve Bruce who was in charge for the 200th time. The final, on 28 May 2016 at Wembley Stadium, was a local derby against Sheffield Wednesday who beat Brighton & Hove Albion 31 on aggregate in the other semi-final. Hull beat Sheffield Wednesday 10 in the final with the only goal coming from a 25-yard wonder strike by Mohamed Diame in the 72nd minute. The Tigers made an immediate return to the top flight and it was Bruce's fourth promotion to the Premier League as manager.

Question: Where was the prime minister who survived a vote of confidence after the 1906 election born? Passage:Heftye served one term in Kristiania city council, from 1907 to 1910. On 19 March 1908, when the Knudsen's First Cabinet assumed office, he was appointed for his second term as Minister of Defence. He resigned already on 10 April the same year, because Prime Minister Gunnar Knudsen refused to seek a vote of confidence in Parliament, a form of investiture. This was a problematic question at that time, as Norway had made important steps towards parliamentarism, but not formalized the process with change of government. Former Prime Minister Christian Michelsen had asked for a vote of confidence following the 1906 general election, and survived. When he retired from politics in 1907 due to illness, Jrgen Lvland took over, but he was felled in 1908. In early 1908, the Liberal Party had evicted 24 legislators who supported Christian Michelsen and the endeavors of the Coalition Party (later leading to the creation of the Liberal Left Party), and hence, when Knudsen took over, he had no way of achieving a parliamentary majority. In that situation he could not expect to survive a vote of confidence. It has been said that parliamentarism works best in a two-party system, which Norway did not have at that time, and has never had since, although the Coalition Party tried to implement it. On the other hand, Knudsen and his cabinet resigned following the 1909 general election, which the Liberal Party lost. Such an action is not required by law, but if not carried through, the cabinet would most likely face a vote of no confidence.
