[EX Q]: Question: Which horse came in second in the King's Plate the year that Bunty Lawless was the top 3-year old in Canada? Passage:Racing during the Great Depression of the 1930s, Bunty Lawless competed for purse money that was very small. At age two, he finished first or second in all but one of his ten races. The one time he was out of the money that year was in the Cup and Saucer Stakes, when his equipment broke. In 1938, the horse was the top 3-year-old in Canada, and his victory in the King's Plate, his country's most prestigious race, was enormously popular with the public. In an era when millionaires still dominated Thoroughbred horse racing, the owner and breeder of Bunty Lawless was the opposite. The working man's hero, Willie Morrissey grew up penniless in the poorest section of Toronto, worked as a newsboy, then became a successful hotel owner and boxing promoter. At the race track, he sat in the cheap grandstand seats with the rest of the crowd and was frowned upon by the aristocratic elite owners in their top hats and tails, seated in their exclusive viewing boxes.

[EX A]: In 1938, the horse was the top 3-year-old in Canada, and his victory in the King's Plate, his country's most prestigious race, was enormously popular with the public

[EX Q]: Question: How old was the actor who played the Ninth Doctor at the end of his run? Passage:The regeneration of the Ninth Doctor into the Tenth at the end of "The Parting of the Ways" (2005) used computer effects to morph Christopher Eccleston into David Tennant. In the episode of Doctor Who Confidential accompanying the episode "Utopia" (2007), where the same effect is used for the Master's regeneration, it is stated that the production team decided that this would be a common effect for all future Time Lord regenerations, rather than each regeneration being designed uniquely at the whim of the individual director. This style of transition is seen again in "The Stolen Earth"/"Journey's End" (2008) both when the Doctor undergoes an aborted regeneration, and when his hand spawns a clone in the second part; in The End of Time (2010) during which Matt Smith took over the role as the Eleventh Doctor; in "The Impossible Astronaut" when the Doctor is shot twice and seemingly killed; in "Day of the Moon" when a young girl regenerates; and in "Let's Kill Hitler" when Mels (Nina Toussaint-White) is shot and regenerates into River Song (Alex Kingston). "The Night of the Doctor" and "The Day of the Doctor" subsequently use the effect to show the Eighth Doctor and War Doctor's regenerations respectively. The Eighth Doctor's regeneration into the War Doctor uses steady beams of light as opposed to the flame effect used for other revived series regenerations. In the Series 10 episode "The Lie of the Land", the Twelfth Doctor fakes a regeneration as part of a plan to test if Bill still has free will. The effect used is consistent with the one used in the modern series, with the Doctor's hands glowing and emitting regeneration energy before he enters full regeneration. However, as the regeneration was not real, it did not use up a regeneration and the Doctor did not change bodies.

[EX A]: The regeneration of the Ninth Doctor into the Tenth at the end of "The Parting of the Ways" (2005) used computer effects to morph Christopher Eccleston into David Tennant

[EX Q]: Question: How many brothers and sisters did Wieniawa-Długoszowski's future wife have? Passage:In 1914 he moved to Kraków and joined the First Cadre Company which fought on the Austro-Hungarian side against Russia. In October 1914 he became a commander of a platoon of a squadron in . During the fighting in 1914–1915 he was promoted to lieutenant, and after the war he was awarded the V-Class Virtuti Militari. In August 1915 he moved to the special group in Warsaw. Soon he became an aide-de-camp to Józef Piłsudski. In 1918, he was sent on a mission to Russia. He was given three tasks; to persuade General Józef Haller's army, then in the Ukraine, to back Piłsudski (he failed in this task), to reach the French military mission in Moscow under General Lavergne (he succeeded in this task) and to return from Moscow to Paris to liaise with the government there. Unfortunately he was arrested by the Soviet Cheka as a member of the Polish Military Organisation while on a French diplomatic train on its way from Moscow to Murmansk (and Paris). He was imprisoned in the Taganka prison. He was freed thanks to the intervention of his future wife Bronisława Wieniawa-Długoszowska with the much feared Cheka operative Yakovleva, then in charge of the prison. Bronisława was at that time married to the lawyer , the lawyer of Felix Dzerzhinsky, the head of the Cheka. She was a Lutheran, her family having converted from the Jewish faith when she was eight.

[EX A]:
