Q: 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.

Q: Question: Which college where Harben was educated has the highest enrollment? Passage 1:The towers were designed as framed tube structures, giving tenants open floor plans, unobstructed by columns or walls. The framed tube design was introduced by Bangladeshi-American structural engineer Fazlur Rahman Khan in the 1960s. The design was accomplished by using many closely spaced perimeter columns, providing much of the structure's strength, with the gravity load shared with the core columns. The elevator system, which made use of sky lobbies and a system of express and local elevators, allowed substantial floor space to be used for office purposes by making the structural core smaller. The design and construction of the towers involved many other innovative techniques, such as wind tunnel experiments and the slurry wall for digging the foundation. Yamasaki also incorporated elements of Islamic architecture in the building's design, having previously designed Saudi Arabia's Dhahran International Airport with the Saudi Binladin Group.
 Passage 2:Beagle is a crater lying within the Margaritifer Sinus quadrangle (MC-19) portion of the planet Mars, the crater is one of multiple topographical depressions within the Meridiani Planum extraterrestrial plain, which was explored by the Opportunity rover. It was located by the rover in images taken on sol 855 (June 20, 2006), 310 metres (1,107 ft) away. It is on the edge of the much larger ejecta blanket surrounding the crater Victoria, named the Victoria Annulus. This impact crater was named in honor of HMS Beagle of the Royal Navy, ordered in February 1817, which carried Charles Darwin on his voyage round the world.
 Passage 3:He was the son of Henry Andrade Harben and the grandson of Sir Henry Harben who founded Prudential Assurance, Harben was educated at Eton College and Magdalen College, Oxford, before qualifying as a barrister. He married Agnes Helen Bostock. He stood unsuccessfully for the Conservative Party in Eye at the 1900 general election, but by 1902 had switched his affiliation to the Liberal Party. He stood for the Liberal Party in Worcester at the 1906 general election. Although he lost the election, he petitioned the election court on the grounds that supporters of the winner, George Henry Williamson, had engaged in widespread bribery. He won the case, but the seat was left vacant until a by-election in 1908, and the local Liberal Party adopted a new candidate. Harben next stood in Portsmouth at the December 1910 general election, but came bottom of the poll.

Q: Question: What is the town where McLaren was born known for? Passage 1:Like his father, Mellon consistently supported the Republican Party, and he frequently donated to state and local party leaders. Through state party boss Matthew Quay, Mellon influenced legislators to place high tariffs on aluminum products in the McKinley Tariff of 1890. During the early 20th century, Mellon was dismayed by the rise of progressivism and the antitrust actions pursued by the presidential administrations of Theodore Roosevelt, William Howard Taft, and Woodrow Wilson. He especially opposed the Taft administration's investigations into Alcoa, which in 1912 signed a consent decree rather than going to trial. In the aftermath of World War I, he provided financial support to Henry Cabot Lodge and other Republicans in their successful campaign to prevent ratification of the Treaty of Versailles. Mellon attended the 1920 Republican National Convention as a nominal supporter of Pennsylvania Governor William Cameron Sproul (Mellon hoped Senator Philander Knox would win the nomination), but the convention chose Senator Warren G. Harding of Ohio as the party's presidential nominee. Mellon strongly approved of the party's conservative platform, and he served as a key fundraiser for Harding during the presidential campaign.
 Passage 2:He was born at Launceston in Tasmania to draper Alexander Morrison McLaren and Elsie Elizabeth Gibbins. He attended Caulfield Grammar School and then the University of Melbourne, becoming an accountant. In 1938 he embarked on a world tour, returning in 1939. He served in the Royal Australian Navy from 1942 to 1945 and returned to become a partner in the accountancy firm Harris & McLaren. On 16 April 1941 he married Eileen Porter, with whom he had four children. From 1945 to 1947 he was the independent member for Glen Iris in the Victorian Legislative Assembly. Following his defeat he joined the Liberal Party, and served on Malvern City Council from 1951 to 1953. From 1957 to 1963 he was national president of the YMCA, and he served as world vice-president from 1961 to 1969; he was also awarded the OBE in 1959. In 1965 he returned to the Legislative Assembly as the Liberal member for Caulfield, changing seats to Bennettswood in 1967. From 1973 he was Deputy Speaker. McLaren retired from politics in 1979, and died in 2000.
 Passage 3:In 1341, the Byzantine Empire was in a state of turmoil, and despite the restoration of the Empire's capital to Constantinople and the recovery of a measure of its former power by Michael VIII Palaiologos (r. 1259–1282), the policies implemented during his reign had exhausted the state's resources, and the Empire's strength waned under his successor, Andronikos II Palaiologos (r. 1282–1328). During Andronikos II's long reign, the remaining Byzantine possessions in Asia Minor slowly fell to the advancing Turks, most notably the newly established Ottoman emirate. This caused a flood of refugees into Byzantium's European provinces, while at the same time the Catalan Company wrought havoc in the imperial domains. Taxes also rose dramatically to finance tributes to the Empire's enemies. A combination of these failures and personal ambition moved the Emperor's grandson and heir, the young Andronikos III Palaiologos, to revolt. Supported by a group of young aristocrats led by John Kantakouzenos and Syrgiannes Palaiologos, Andronikos III deposed his grandfather after a series of conflicts during the 1320s. Although successful in removing the old Emperor from power, the war did not augur well for the future, as the Empire's neighbours—the Serbs, Bulgarians, Turks, Genoese and Venetians—took advantage of Byzantine infighting to gain territory or expand their influence within the Empire.
