Input: Consider Input: Question: What types of planes did the Australian Flying Corps use the year Holden volunteered for them? Passage 1:"Where the Dream Takes You" is a "tender" pop power ballad with contemporary R&B, soul and lite rock influences, performed in an urban contemporary style. According to the song's official sheet music, published by Walt Disney Music Publishing on Musicnotes.com, "Where the Dream Takes You" is set in signature common time and performed at a moderate tempo of 88 beats per minute in the key of C major. The Disney Song Encyclopedia author Thomas S. Hischak believes that the song's lyrics are "about following your heart to find your true self", which begin "They'll try to hold you back, they will say you're wrong, but they will never understand, no, the journey that you're on." A writer for Barnes & Noble agreed that, thematically, the single "correlates to the film's tale of an inexperienced young adventurer", Milo Thatch, and its diverse cast of supporting characters, all of whom long to follow various dreams of their own as they search for Atlantis. One of its verses reads, "There's something in your soul/That won't be denied/It's the faith to dream that keeps the dream alive/So you still believe and you know you must go", encouraging listeners to follow their dreams despite others' opinions. Lasting a duration of four minutes, AllMusic cites the song's mood as both "earnest" and "mellow"; Mýa performs it using a "sweet vocal", which spans two octaves from G3 to D♭5. Based on a melody heard only briefly during the film, "Where the Dream Takes You" encompasses "soft, contemporary beats" combined with the singer's "dulcet tones" that recall music played in a piano lounge, contrasting with the time period in which the film itself is set. Its production, which has been described as "polished", was handled by Jay Selvester, Robbie Buchanan and Ron Fair.
 Passage 2:The ruins of the Norman Canterbury Castle and St Augustine's Abbey are both open to the public. The medieval St Margaret's Church now houses "The Canterbury Tales", in which life-sized character models reconstruct Geoffrey Chaucer's stories. The Westgate is now a museum relating to its history as a jail. The medieval church of St Alphege became redundant in 1982 but had a new lease of life as the Canterbury Urban Studies Centre, later renamed the Canterbury Environment Centre; the building is used by the King's School. The Old Synagogue, now the King's School Music Room, is one of only two Egyptian Revival synagogues still standing. The city centre contains many timber-framed 16th and 17th century houses, however there are far fewer than there were before the Second World War, as many were damaged during the Baedeker Blitz. Many are still standing, including the "Old Weaver's House" used by the Huguenots. St Martin's Mill is the only surviving mill out of the six known to have stood in Canterbury. It was built in 1817 and worked until 1890; it is now a house conversion. St Thomas of Canterbury Church is the only Roman Catholic church in the city and contains relics of Thomas Becket.
 Passage 3:Holden enlisted in the Australian Imperial Force on 26 May 1915, and was posted to the 4th Light Horse Brigade as a private. He departed for Egypt aboard the transport A29 Suevic on 13 June. Serving as a driver first in the Middle East and then on the Western Front, his mechanical ability and sense of adventure led him to volunteer for the Australian Flying Corps (AFC) in December 1916. After qualifying as a pilot in England, he was commissioned a lieutenant and posted to No. 2 Squadron. Commanded by Major Oswald Watt, No. 2 Squadron's personnel included many former Lighthorsemen, as well as mechanics from the AFC's first combat formation, the Mesopotamian Half Flight. The force trained extensively in England commencing in January 1917, before deploying to the Western Front that September. Holden was involved in the AFC's first day of combat in France; just after noon on 2 October, in the vicinity of Saint-Quentin, he and his wingman engaged a German two-seater that managed to escape.

Input: Consider Input: Question: Who was the head monk at Alvastra Abbey when Stephen lived there? Passage 1:Shortly after he returned to England in bad health. From 1777 to 1779 he commanded , as flag captain to his father at Newfoundland. On his return he was appointed to the 32-gun frigate HMS Pearl, which when cruising near the Azores on 14 September 1779, captured the Spanish frigate Santa Monica of equal force. In December Pearl sailed with the fleet under Sir George Rodney, and assisted in the capture of the Caracas convoy; but having sprung her foremast, was ordered home with the prizes. She was afterwards sent out to North America, and on 30 September 1780, while on a cruise off the Bermudas, captured the Espérance, a frigate-built privateer of 32 guns. In the battle of Cape Henry, on 16 March 1781, she acted as repeating frigate. She was not with the fleet during the battle of the Chesapeake on 5 September, but joined it, still off Cape Henry, on the 14th, and was left to keep watch on the movements of the French till the 25th, when she sailed for New York. On 19 October she sailed again with the fleet, and on the 23rd was stationed ahead as a look-out (Pearl's Log). She returned to England in 1782.
 Passage 2:The first Archbishop of Uppsala was Stephen, a Cistercian monk from the celebrated Alvastra Abbey. Cardinal William of Sabina came as papal legate to Sweden during the archiepiscopate of Jarler, a Dominican friar (1235–55). The legate had been commissioned, among other things, to establish cathedral chapters wherever such were lacking, and to grant them the exclusive right of electing the bishops. Another important matter which the legate had been ordered to carry out was the enforcement of the law of clerical celibacy. At a provincial synod held at Skänninge in 1248 under the presidency of the cardinal, the rules as to celibacy were made more severe. The pious and energetic Archbishop Jarler and his successor Laurentius (1257–67), a Franciscan, constantly strove to elevate the clergy and to enforce the law of celibacy. A century later Saint Bridget (d. 1373), laboured zealously for the enforcement of the same law.
 Passage 3:Held against the backdrop of the 2008 Serbian presidential elections — contested between incumbent Boris Tadić from the ruling center-left Democratic Party (DS) and challenger Tomislav Nikolić from the opposition right-wing Serbian Radical Party (SRS) — as well as speculation that Albanians from Serbia's province of Kosovo were in the final stages of coordination with the United States to unilaterally declare independence, the festival received plenty of attention both in the Serbian and foreign press. Political angles and overtones dominated foreign press reports such as the one by in center-left Libération who, after giving praise to the festival for celebrating auteur cinema, wondered if the fact that festival's jury is headed by Peter Handke — whom she described as someone "who still smelled of sulfur after being at Milošević's funeral and who wrote about Serbs in panegyric form due to seeing them unjustly accused of all evils" — also mean that Kusturica adheres to these ideas. She answers her own question by saying that, like Handke, Kusturica also believes western Europeans have demonized Serbs and Serbia, but that the Serbian director supports center-left candidate Tadić at the presidential elections.

Input: Consider Input: Question: What units did the Colonel Warrington served under inn the Texas-Indian Wars command? Passage 1:Lewis Warrington III, the grandson of War of 1812 naval hero Commodore Lewis Warrington, was born in Washington, D.C. and later entered the United States Army there. He was assigned to the 4th U.S. Cavalry Regiment as a second lieutenant on June 18, 1867, and then made a first lieutenant on July 31, 1869. Warrington spent most of his career on the Texas frontier and served under Colonel Ranald S. Mackenzie during the Texas-Indian Wars of the 1870s. On December 8, 1874, he and ten cavalrymen pursued a group of hostile Comanche Indians through the Muchague Valley. Both groups were riding at a full gallop and several riders of Warrington's unit were left behind. Warrington personally captured one Indian, turning him over to a trooper whose horse could not continue, and resumed the pursuit with Privates Frederick Bergendahl and John O'Sullivan. After five miles, their horses exhausted, the Comanches dismounted and decided to shoot it out with the troopers. Climbing out of the valley onto the plain, they opened fire on Warrington and his men as they climbed up after them. Warrington eventually became separated from the others and found himself at the mercy of five Comanche warriors. He was forced to fight them off single-handed and, after exhausting his ammunition, used his rifle as a club in hand-to-hand combat. Bergendahl and O'Sullivan found themselves in a similar situation and killed all but one of their attackers. O'Sullivan pursued the lone survivor but was unable to catch him. All three men received the Medal of Honor four months later, Warrington being the only officer of the Indian Wars to receive the award following the battle rather than years afterwards like other officers. Warrington died on January 5, 1879, and was buried in San Antonio National Cemetery.
