[EX Q]: Question: What side was the Austro-Hungarian army on? Passage:Antoni Chruściel was born on 16 July 1895 in the village of Gniewczyna Łańcucka halfway between Łańcut and Przeworsk, to Andrzej Chruściel, a local farmer and the vogt of that village. In 1909, while still a student at a local gymnasium in Jarosław, Chruściel joined the secret scouting troop; he was also active in the Zarzewie movement. In 1914, after the outbreak of the First World War he moved to Lwów, where he joined the Eastern Legion. Soon afterwards, as a citizen of Austria-Hungary, he was drafted into the Austro-Hungarian Army. After graduating from an NCO school in May 1915 he served at various posts, including his service as a commanding officer of a company of the 90th Infantry Regiment. After the dissolution of Austria-Hungary and the chaos at the eastern front, Chruściel's regiment was the only unit in the entire Austro-Hungarian Army to return to the barracks as an organized entity and with arms. Few weeks later Chruściel, together with most of his unit, joined the newly formed Polish Army.

[EX Q]: Question: Which of the two major races held in New York occurs before the other each year? Passage:An avid sportsman, Pierre Lorillard and his brother, George Lyndes Lorillard, were both major figures in Thoroughbred horse racing. In 1874, Pierre's horse, Saxon, won the Belmont Stakes. Although his horse Parole finished fourth in the 1876 Kentucky Derby, it went on to race with considerable success both in the United States and in Europe. In the 19th century, shipping horses from New York to Louisville, Kentucky was a major undertaking and as the Preakness Stakes and the Belmont Stakes were both held in the New York City area in the period, neither of the Lorillard brothers entered horses again in the Kentucky Derby. Pierre Lorillard established Rancocas Stable, named for the New Jersey town where he owned a country house. He spent time in Paris and in England where, in 1881, his horse Iroquois became the first American-owned and bred horse to win a European classic race. Ridden by the champion English jockey Fred Archer, Iroquois won The Derby and then went on to capture the St. Leger Stakes as well. Lorillard had other successes in England, notably with the horse named for the actor David Garrick, which won the 1901 Chester Cup ridden by American jockey, Danny Maher.
