Input: Consider 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.

Input: Consider Input: Question: Of the grasses that the essex skipper eats, which is the longest? Passage:Eggs are laid in strings on the stems of grasses where they remain over the winter. The Essex skipper's favoured foodplant is cock's-foot (Dactylis glomerata), and it rarely uses the small skipper's favoured foodplant Yorkshire fog. Essex skippers' other foods include creeping soft grass (Holcus mollis), couch grass (Elymus repens), timothy-grass (Phleum pratense), meadow foxtail (Alopecurus pratensis), false brome (Brachypodium sylvaticum) and tor-grass (Brachypodium pinnatum). This skipper's caterpillars emerge in the spring and feed until June before forming shelters from leaves tied with silk at the base of the foodplant to pupate. Adults fly from July through August. Like most skippers, they are fairly strictly diurnal, though individuals are very rarely encountered during the night.

Input: Consider Input: Question: How long is the road that runs through Carneys Point Township? Passage:The first of CR 540 are concurrent with the entire length of Route 140, running southeast through commercial areas of Carneys Point Township from an intersection with US 130 and interchanging with I-295 and the New Jersey Turnpike/US 40 at the point US 40 splits from the New Jersey Turnpike. From the east end of Route 140, signage for CR 540 begins past US 40, with the route heading southeast on two-lane undivided Hawks Bridge Road. The road runs through residential neighborhoods before crossing the Salem River into Mannington Township. The route intersects CR 631 as it heads through forests before entering a mix of woods and farms as the road turns south and briefly becomes a divided highway at the CR 646 junction. From here, CR 540 becomes Pointers Road and runs through more agricultural areas, crossing the marshy Mannington Creek before briefly turning southeast onto Bypass Road and intersecting CR 620 and Route 45.
