Teacher: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.
Teacher: Now, understand the problem? Solve this instance: Question: Who was the pope before Bruno of Toul? Passage 1:In a publication of 1941, Norman Tindale, together with the American anthropologist Joseph Birdsell, published a paper suggesting that there were 12 Negrito tribes living on the coastal and rainforest areas around Cairns. The idea had been developed by Birdsell during field work in 1937-8. They were characterized by very short stature, curly hair, and yellowy-brown skin. Six of them were Dyirbal speakers, such as the Jirrbal, Girramay, Gulngai and Djiru within the Murray Upper/Tully Area. Of the others, located further north beyond Cairns, two spoke varieties of Djabugay, and three spoke dialects of Yidin. The remaining tribe were the Mbabaram, whom Tindale took to be strong evidence for his hypothesis because their language, in so far as it had been reported, diverged substantially from the surrounding tongues, and appeared to be wholly atypical, compared to the standard Australian aboriginal languages.
Passage 2:According to some chroniclers, Hildebrand moved to Cluny after Gregory VI's death, which occurred in 1048; his declaration to have become a monk at Cluny must not be taken literally. He then accompanied Abbot Bruno of Toul to Rome; there, Bruno was elected pope, choosing the name Leo IX, and named Hildebrand as deacon and papal administrator. Leo sent Hildebrand as his legate to Tours in France in the wake of the controversy created by Berengar of Tours. At Leo's death, the new Pope, Victor II, confirmed him as legate, while Victor's successor Stephen IX sent him and Anselm of Lucca to Germany to obtain recognition from the Empress Agnes de Poitou. Stephen died before being able to return to Rome, but Hildebrand was successful; he was then instrumental in overcoming the crisis caused by the Roman aristocracy's election of an antipope, Benedict X, who, thanks also to Agnes's support, was replaced by the Bishop of Florence, Nicholas II. With the help of 300 Norman knights sent by Richard of Aversa, Hildebrand personally led the conquest of the castle of Galeria Antica where Benedict had taken refuge. Between 1058 and 1059, he was made archdeacon of the Roman church, becoming the most important figure in the papal administration.
Passage 3:In later years, Continental Express continued to serve the airport with nonstop regional jet flights to Cleveland while Continental Connection was operating nonstop turboprop flights to Albany, NY; however, both services ended in 2005. Spirit Airlines scheduled flights to several Florida cities and Detroit, before moving to LaGuardia Airport in 2001; in May 2008 the airline resumed service to Fort Lauderdale from MacArthur only to drop it soon after. Delta Express, which had nonstops to Orlando and Fort Lauderdale, dropped MacArthur Airport in 2003 after a decline in traffic. Delta Connection regional jet service to Atlanta flown by Atlantic Southeast Airlines (ASA) on behalf of Delta Air Lines ended on May 1, 2008 following a mid-April announcement that Delta and Northwest Airlines were planning to merge a move that led to changes for the merged airline.
