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: How long had Stalin been the leader of the Soviet Union by the year 1937? Passage:Inside the SAPD, the first part of 1937 saw an intensification of differences over attitudes to a possible political party of the united left or a Popular front, and more precisely over the party's approach to the Soviet Union. The differences led to Peter Blachstein's exclusion from the SAPD. Others excluded at the same time included his political mentor and Erwin Ackerknecht: the three became the focus of a short-lived political grouping known as "Neuer Weg" ("New Way"). Blachstein was also affected more directly by the intense political tensions radiating out from Moscow, based on Stalin's suspicions - not entirely unfounded - that there might be comrades in the Soviet Union and further west in Europe who favoured an alternative Soviet leader. The POUM, of which Blachstein was a member, backed a broadly Trotskyite vision for a communist future and its members therefore became targets for Soviet agents. In June 1937 Blachstein was arrested in Barcelona by communist secret police and accused of spying for Franco and working for the Gestapo. With approximately 100 other foreign detainees he was taken to a large garage which had been adapted for use as an ad hoc prison. Because of the appalling hygiene he soon fell ill with Tuberculosis, as a result of which he was transferred to a sanatorium controlled by anarchist comrades. Helped by Spanish friends, in January 1938 he succeeded in escaping back to France.
