input question: Given the following context:  The Imperial Trans-Antarctic Expedition of 1914–1917 is considered to be the last major expedition of the Heroic Age of Antarctic Exploration. Conceived by Sir Ernest Shackleton, the expedition was an attempt to make the first land crossing of the Antarctic continent. After Amundsen's South Pole expedition in 1911, this crossing remained, in Shackleton's words, the “one great main object of Antarctic journeyings”.  The expedition failed to accomplish this objective, but became recognized instead as an epic feat of endurance. Shackleton had served in the Antarctic on the Discovery Expedition of 1901–1904, and had led the Nimrod Expedition of 1907–1909. In this new venture he proposed to sail to the Weddell Sea and to land a shore party near Vahsel Bay, in preparation for a transcontinental march via the South Pole to the Ross Sea. A supporting group, the Ross Sea party, would meanwhile establish camp in McMurdo Sound, and from there lay a series of supply depots across the Ross Ice Shelf to the foot of the Beardmore Glacier. These depots would be essential for the transcontinental party's survival, as the group would not be able to carry enough provisions for the entire crossing. The expedition required two ships: Endurance under Shackleton for the Weddell Sea party, and Aurora, under Aeneas Mackintosh, for the Ross Sea party. Endurance became beset in the ice of the Weddell Sea before reaching Vahsel Bay, and drifted northward, held in the pack ice, throughout the Antarctic winter of 1915. Eventually the ship was crushed and sunk, stranding its 28-man complement on the ice. After months spent in makeshift camps as the ice continued its northwards drift, the party took to the lifeboats to reach the inhospitable, uninhabited Elephant Island. Shackleton and five others then made an 800-mile (1,300 km) open-boat journey in the James Caird to reach South Georgia. From there, Shackleton was eventually able to mount a rescue of the men waiting on Elephant Island and bring them home without loss of life. On the other...  answer the following question:  What required two ships????
output answer: The Imperial Trans-Antarctic Expedition of 1914–1917

Given the following context:  Throughout most of its history, Istanbul has ranked among the largest cities in the world. By 500 CE, Constantinople had somewhere between 400,000 and 500,000 people, edging out its predecessor, Rome, for world's largest city. Constantinople jostled with other major historical cities, such as Baghdad, Chang'an, Kaifeng and Merv for the position of world's most populous city until the 12th century. It never returned to being the world's largest, but remained Europe's largest city from 1500 to 1750, when it was surpassed by London.The Turkish Statistical Institute estimates that the population of Istanbul Metropolitan Municipality was 14,377,019 at the end of 2014, hosting 19 percent of the country's population. Then about 97–98% of the inhabitants of the metropolitan municipality were within city limits, up from 89% in 2007 and 61% in 1980. 64.9% of the residents live on the European side and 35.1% on the Asian side. While the city ranks as the world's 5th-largest city proper, it drops to the 24th place as an urban area and to the 18th place as a metro area because the city limits are roughly equivalent to the agglomeration. Today, it forms one of the largest urban agglomerations in Europe, alongside Moscow. The city's annual population growth of 3.45 percent ranks as the highest among the seventy-eight largest metropolises in the Organisation for Economic Co-operation and Development. The high population growth mirrors an urbanization trend across the country, as the second and third fastest-growing OECD metropolises are the Turkish cities of İzmir and Ankara. Istanbul experienced especially rapid growth during the second half of the 20th century, with its population increasing tenfold between 1950 and 2000. This growth in population comes, in part, from an expansion of city limits—particularly between 1980 and 1985, when the number of Istanbulites nearly doubled. The remarkable growth was, and still is, largely fueled by migrants from eastern Turkey seeking employment and improved living conditions. The...  answer the following question:  Where are the migrants coming from that fuel the growth of the city that is number one in OCED growth?
----
Answer: eastern Turkey

Problem: Given the question: Given the following context:  Throughout the 360° Tour, the band worked on multiple album projects, including: a traditional rock album produced by Danger Mouse; a dance record produced by RedOne and will.i.am; and Songs of Ascent. However, the latter was not completed to their satisfaction, and by December 2011, Clayton admitted it would not come to fruition. The sessions with Danger Mouse instead formed the foundation of U2's next album, and they worked with him until May 2013 before enlisting the help of producers Paul Epworth, Ryan Tedder, Declan Gaffney, and Flood. The band suspended work on the album late in 2013 to contribute a new song, "Ordinary Love", to the film Mandela: Long Walk to Freedom. The track, written in honour of Nelson Mandela, won the 2014 Golden Globe Award for Best Original Song. In November 2013, U2's long-time manager Paul McGuinness stepped down from his post as part of a deal with Live Nation to acquire his management firm, Principle Management. McGuinness, who had managed the group for over 30 years, was succeeded by Guy Oseary. In February 2014, another new U2 song, the single "Invisible", debuted in a Super Bowl television advertisement and was made available in the iTunes Store at no cost to launch a partnership with Product Red and Bank of America to fight AIDS. Bono called the track a "sneak preview" of their pending record.On 9 September 2014, U2 announced their thirteenth studio album, Songs of Innocence, at an Apple product launch event, and released it digitally the same day to all iTunes Store customers at no cost. The release made the album available to over 500 million iTunes customers in what Apple CEO Tim Cook called "the largest album release of all time." Apple reportedly paid Universal Music Group and U2 a lump sum for a five-week exclusivity period in which to distribute the album and spent US$100 million on a promotional campaign. Songs of Innocence recalls the group members' youth in Ireland, touching on childhood experiences, loves and losses, while paying tribute to their musical...  answer the following question:  What was the name of the album that had it's press tour interrupted after Bono was seriously inured in a bicycle accident in Central Park on 16 November 2014?

The answer is:
Songs of Innocence
