Q: In this task, you're given a question, along with three passages, 1, 2, and 3. Your job is to determine which passage can be used to answer the question by searching for further information using terms from the passage. Indicate your choice as 1, 2, or 3.
Question: Who was the leader of Yugoslavia in 1923? Passage 1:As part of Middle Tennessee, Grundy County has historically been one of the strongest Democratic counties in the state. It voted Democratic in every presidential election from 1912 to 2004, except for in 1968 (when segregationist George Wallace won the county), and 1972 when many traditional Democratic voters around the nation rejected the perceived radical liberal George McGovern in favor of incumbent Republican Richard Nixon. However, like most of the rural south, Grundy County has shifted towards the Republican Party in recent years, but was one of the last counties in Tennessee to make the switch to the party. The last Democratic Presidential candidate to win Grundy County was John Kerry in 2004, who won 18 out of Tennessee's 95 counties, whereas Al Gore won 36 in 2000. Grundy County was also won by Democratic U.S senate candidates Bob Clement in 2002 and Harold Ford Jr. in 2006, both of whom lost. Republican Presidential nominee John McCain won the county by nearly 13% in 2008, becoming the first Republican Presidential candidate to win Grundy County since Nixon won it 36 years earlier, and by 2016, Grundy County had taken a major shift toward the GOP, when Republican Donald Trump received 76% of the vote, a figure closer to what is usually seen in historically Republican East Tennessee counties.
 Passage 2:In 1923 it was organised the first edition of leagues in the Kingdom of Yugoslavia where, beside the top-level national Yugoslav Football Championship, regional championships were also played. The clubs of the Drina Banovina, part of Littoral Banovina and Vrbas Banovina, territorially similar to present day Bosnia and Herzegovina, played within the Sarajevo Football Subassociation League until 1939. The champions of Subassociation Leagues were granted a place in the qualifiers to the Yugoslav Championship, a top national level. SAŠK (1923, 1924, 1925, 1926, 1927, 1928, 1930/31), Slavija (1929, 1930, 1932/33, 1934/35, 1935/36, 1936/37, 1937/38, 1938/39, 1939/40), FK Krajišnik Banja Luka (1935/36) were the clubs to manage to participate in the national league, first in 1923 when the championship was played in a cup system. In 1939 the Yugoslav league system was changed, with the creation of separate Serbian and Croato-Slovenian Leagues which will serve as qualifying leagues for the final phase of the Yugoslav Championship. The clubs from the Sarajevo Subassociation played their qualifications to the Serbian League, however Slavija Sarajevo managed to participate, in 1939–40 (3rd place) and 1940–41 (9th place) and played their qualifications to the Croatian-Slovenian League, however SAŠK managed to participate, and it did it in both occasions, in 1939–40 (5th place) and 1940–41 (5th place). That became the last season before the beginning of the Second World War.
 Passage 3:Richardson is a right-arm fast bowler, and says that, due to his height (178cm) and frame ("70 odd kilos"), he was initially discouraged by coaches to become a pace bowler, a role generally associated with taller and weightier cricketers. He made his List A debut for Western Australia on 21 October 2015 in the 2015–16 Matador BBQs One-Day Cup. In December 2015 he was named in Australia's squad for the 2016 Under-19 Cricket World Cup. On 16 January 2016 he made his Twenty20 debut for the Perth Scorchers in the 2015–16 Big Bash League. He made his first-class debut for Western Australia on 15 March 2016 in the 2015–16 Sheffield Shield.
