Example Input: 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.

Example Input: Question: In what city did one of Austin Town's legends and local heros lead India to victory in during the 1951 Asian Games? Passage:Unlike other parts of Bangalore where Cricket is popular, Football is a passion for the residents of Austin Town. According to football coach Thyagarajan, Austin Town is considered the birthplace of Football in Bangalore. The origins of the game can be traced to the Italian soldiers who were being held as prisoners of war during the beginning of WWI in the Bangalore Cantonment. The Italian POWs passed on the game to the natives, even though at first the natives played football bare-footed. (Some players played without boots even in the Olympics.) The very first Olympians – Anthony, Kanniah, Raman and Shanmugham – who represented the Indian Football team in the Olympic Games of 1948 and 1952, were from Austin Town. Vajravelu and Varadarajan were from the City area, and the rest of the players were from the Bangalore Cantonment. Most of the Football enthusiasts in Austin Town are the Tamil Community, with many of the local boys now playing for clubs in Goa and Calcutta. In the 1960s and 1970s, many of the Austin Town boys made it the Football teams of Government and defence companies such as HMT, MEG, ITI, NGEF, HAL, BEML, BHEL, ADA, ADE, etc. Austin Town and Murphy Town are still considered gold-mines of football talent. One of Austin Town's legend and local hero is 95-year-old T Shanmugham, who led India to victory in Football in the 1951 Asian Games, and also was part of India's Football team for the 1952 Olympics. The Austin Town Football Grounds is now known as Nandan Ground's after one of Indian Football's greatest goalkeeper Nandan, who was also from Austin Town. Austin Town is also the birthplace of other legendary football players such as Ulaganathan and former Captain Carlton Chapman.
