Example Input: Question: Were the Subics the dominant ethnic group of Bosnia? Passage:In 1290 Hungarian King Ladislaus IV died leaving no heirs to the throne. The cousin of Ladislaus IV, Andrew III, was crowned King, despite the desire of the sister of the former King Ladislaus IV, Mary of Hungary, Queen of Naples, who wanted her son, Charles Martel as the new King in Hungary. The latter party had much more support, so Pope Nicholas IV had crowned Charles Martel as King of Hungary. This movement was supported by the most powerful Croatian nobility, the Šubićs, Princes of Bribir. As the current head of the family, Paul Šubić was also son-in-law of King Stefan Dragutin, family connections made Kotroman support Charles Martel's crowning. To increase his influence in Kotroman's realm, Charles Martel issued numerous edicts to split the land among the lesser gentry to gain support for his reign. It appears that he gave the reign over Bosnia to the Šubićs. Charles Martel died unexpectedly in 1295, before the campaign to cease the power in Hungary was finished. The Queen of Naples and sister of former King Ladislaus IV, Mary, had then decided to put her grandson, son of Charles Martel, Charles Robert as the future King of Hungary. Pope Boniface VIII declared the twelve-year-old boy as King Charles I of Hungary in 1297. Paul Šubić of Croatia declared himself as "Dominus of Bosnia" in 1299 and gave the title of Bosnian Ban to his brother, Mladen I Šubić. All of Kotroman's land except for the Lower Edges, which was ruled by Prince Hrvatin Stjepanić as a vassal of the Šubićs, was held by the House of Šubić; as was confirmed by Charles I Robert. Paul Šubić wanted to bring King Charles Robert to Split across Croatia to Zagreb, which would become the main station of his campaign against King Andrew III of Hungary. During the preparations for war, Andrew III died unexpectedly. Charles Robert assessed the Hungarian throne, but had to fight numerous opponents to his regime up to 1309.

Example Input: Question: Where did Warren Harding live the year Coolidge was born? Passage:Calvin Coolidge (born John Calvin Coolidge Jr.; ; July 4, 1872 – January 5, 1933) was an American politician and lawyer who served as the 30th president of the United States from 1923 to 1929. A Republican lawyer from New England, born in Vermont, Coolidge worked his way up the ladder of Massachusetts state politics, eventually becoming governor of Massachusetts. His response to the Boston Police Strike of 1919 thrust him into the national spotlight and gave him a reputation as a man of decisive action. The next year, he was elected vice president of the United States, and he succeeded to the presidency upon the sudden death of Warren G. Harding in 1923. Elected in his own right in 1924, he gained a reputation as a small government conservative and also as a man who said very little and had a rather dry sense of humor.

Example Input: Question: Of the snooker players Robin Hull beat in the pro-am Finnish snooker challenge who was youngest? Passage:In February 2010 Hull took part in the pro-am Finnish Snooker Challenge, which featured a number of notable professionals. He impressed, beating Darren Morgan, Ken Doherty and Matthew Stevens on the way to the final, where he lost to Mark Williams. This result encouraged Hull to take part in the Q School tournament in 2011 in attempt to qualify for the 2011/2012 main tour, which he did successfully in the first event. Due to lack of sponsorship he only played in a handful of events during the season with his best run coming in qualifying for the UK Championship in November where he beat Lucky Vatnani and Yu Delu, before losing to Peter Lines 4–6. Hull did not enter another tournament after this and finished the season ranked world number 84, outside of the top 64 who retain their places for the 2012/2013 season and therefore did not retain his spot on the main tour. In the 2012/2013 season Hull entered qualifying for the World Championship as an amateur, where he lost in the first round of preliminary qualifying 2–5 to Paul Wykes, despite making a 137 break during the match.
