Question: How many soldiers did Britain send to World War I the year Roebuck arrived on the Western Front? Passage:As a boy, Roebuck worked as a trammer and after being sentenced to one month's imprisonment for stealing a watch in 1904, he enlisted in the York and Lancaster Regiment. Over the next seven years, he was stationed in India and Ireland and was promoted to lance corporal, but was demoted back to private in 1910 for "misconduct". He married in 1908 and had two children. Roebuck was discharged into the reserves in 1912 and likely returned to work as a miner prior to becoming a professional footballer in 1913. After Britain's entry into the First World War in August 1914, he was called up by the York and Lancaster Regiment and arrived on the Western Front in September 1914. On 18 October 1914, Roebuck recorded as "presumed dead" after an attack near Beaucamps-Ligny during the Race to the Sea. His death was confirmed by two comrades in January 1915. Roebuck is commemorated on the Ploegsteert Memorial to the Missing.

Question: Which Philadelphia sport team with a fantasy creature mascot was found first? Passage:In the world of sports, mascots are also used for merchandising. Team mascots are often related to their respective team nicknames. This is especially true when the team's nickname is something that is a living animal and/or can be made to have humanlike characteristics. For more abstract nicknames, the team may opt to have an unrelated character serve as the mascot. For example, the athletic teams of the University of Alabama are nicknamed the Crimson Tide, while their mascot is an elephant named Big Al. Team mascots may take the form of a logo, person, live animal, inanimate object, or a costumed character, and often appear at team matches and other related events, sports mascots are often used as marketing tools for their teams to children. Since the mid-20th century, costumed characters have provided teams with an opportunity to choose a fantasy creature as their mascot, as is the case with the Philadelphia Phillies' mascot, the Phillie Phanatic, and the Philadelphia Flyers' mascot, Gritty.

Question: Where was the Chinese pirate who shipwrecked on Tanegashima born? Passage:In 1543, Europeans reached Japan for the first time when a junk belonging to the Chinese wokou pirate lord Wang Zhi carrying Portuguese traders shipwrecked on Tanegashima. The Portuguese introduced the arquebus to the Japanese during this chance encounter, which gave the Japanese, undergoing the bloody Sengoku period at the time, a powerful weapon with which they conducted their internecine wars. The discovery of Japan was attractive to Portuguese merchants and missionaries alike, for it gave the merchants a new market to trade their goods, and the Jesuit missionaries eyed Japan for new converts into Christianity. The warlords of Kyushu vied to get the Portuguese carrack (called the black ship by the Japanese) into their harbours, since the ship also brought considerable wealth to their fiefdoms in addition to the guns.
