Question: Which seasons did Park win the Premier League with Manchester United? Passage:Park began his football career in his native South Korea and played for the Myongji University team before moving to Japan to play for Kyoto Purple Sanga. After Park's national team manager Guus Hiddink moved back to the Netherlands to manage PSV Eindhoven, Park followed him to the Dutch side a year later. After PSV reached the semi-finals of the 2004–05 UEFA Champions League, Park's talents were recognised by Manchester United manager Sir Alex Ferguson and he signed Park for a fee of around £4 million in July 2005. In his time at United, Park won the Premier League four times and also won the 2007–08 UEFA Champions League and the 2008 FIFA Club World Cup. He moved to Queens Park Rangers in July 2012 after suffering a reduction in his number of appearances for Manchester United the previous season. However, an injury-interrupted season with QPR, combined with the club's relegation, led to Park rejoining PSV on loan for the 2013–14 season.

Question: How many people died in the battle that the 1st battalion saw action at in August 1807? Passage:A second battalion was raised in 1804 to increase the strength of the regiment. The 1st battalion embarked for Copenhagen in July 1807 and saw action at the Battle of Copenhagen in August 1807 during the Gunboat War before returning home in November 1807. It then embarked for Portugal in May 1808 for service under General Sir Arthur Wellesley in the Peninsular War and saw action at the Battle of Roliça in August 1808 and the Battle of Vimeiro later that month. In January 1809 the battalion took part in the Battle of Corunna, carrying out successive bayonet charges to keep the French at bay to which General Sir John Moore shouted "Well done, 50th! Well done, my Majors!". The battalion was subsequently evacuated from the Peninsula. Both battalions then embarked from the Downs in July 1809 and saw action in the disastrous Walcheren Campaign. It was the last regiment to leave Holland in December 1809.

Question: Was the Belgian Labour Party socialist? Passage:Achille Honoré Van Acker was born into a working class family in Bruges, Belgium in 1898 as the youngest of 12 children. He only attended school until the age of 11. Despite entering the workforce, Van Acker read widely and joined several social associations in Bruges. At the outbreak of World War I, he was refused by the Belgian Army because he suffered from astigmatism. While the Germans occupied most of Belgium, Van Acker fled into the small section of unoccupied territory behind the Yser Front where he worked in various menial capacities. Mixing with Belgian soldiers during the war, Van Acker became involved in socialist politics, developing a distinctive ideology based on moderate social democracy. After the end of the war, he returned to Bruges and joined the Belgian Labour Party (Belgische Werkliedenpartij, POB–BWP) and became active in socialist groups, trade unions, and cooperatives.
