Example Input: The geographical regions in which Iranian languages were spoken were pushed back in several areas by newly neighbouring languages. Arabic spread into some parts of Western Iran (Khuzestan), and Turkic languages spread through much of Central Asia, displacing various Iranian languages such as Sogdian and Bactrian in parts of what is today Turkmenistan, Uzbekistan and Tajikistan. In Eastern Europe, mostly comprising the territory of modern-day Ukraine, southern European Russia, and parts of the Balkans, the core region of the native Scythians, Sarmatians, and Alans had been decisively been taken over as a result of absorption and assimilation (e.g. Slavicisation) by the various Proto-Slavic population of the region, by the 6th century AD. This resulted in the displacement and extinction of the once predominant Scythian languages of the region. Sogdian's close relative Yaghnobi barely survives in a small area of the Zarafshan valley east of Samarkand, and Saka as Ossetic in the Caucasus, which is the sole remnant of the once predominant Scythian languages in Eastern Europe proper and large parts of the North Caucasus. Various small Iranian languages in the Pamirs survive that are derived from Eastern Iranian.
Example Output: What is another term for Western Iran?

Example Input: Pope John XXIII did not live to see the Vatican Council to completion. He died of stomach cancer on 3 June 1963, four and a half years after his election and two months after the completion of his final and famed encyclical, Pacem in terris. He was buried in the Vatican grottoes beneath Saint Peter's Basilica on 6 June 1963 and his cause for canonization was opened on 18 November 1965 by his successor, Pope Paul VI, who declared him a Servant of God. In addition to being named Venerable on 20 December 1999, he was beatified on 3 September 2000 by Pope John Paul II alongside Pope Pius IX and three others. Following his beatification, his body was moved on 3 June 2001 from its original place to the altar of Saint Jerome where it could be seen by the faithful. On 5 July 2013, Pope Francis – bypassing the traditionally required second miracle – declared John XXIII a saint, after unanimous agreement by a consistory, or meeting, of the College of Cardinals, based on the fact that he was considered to have lived a virtuous, model lifestyle, and because of the good for the Church which had come from his having opened the Second Vatican Council. He was canonised alongside Pope Saint John Paul II on 27 April 2014. John XXIII today is affectionately known as the "Good Pope" and in Italian, "il Papa buono".
Example Output: When did the pope die?

Example Input: The main façade, built from red brick and Portland stone, stretches 720 feet (220 m) along Cromwell Gardens and was designed by Aston Webb after winning a competition in 1891 to extend the museum. Construction took place between 1899 and 1909. Stylistically it is a strange hybrid, although much of the detail belongs to the Renaissance there are medieval influences at work. The main entrance consisting of a series of shallow arches supported by slender columns and niches with twin doors separated by pier is Romanesque in form but Classical in detail. Likewise the tower above the main entrance has an open work crown surmounted by a statue of fame, a feature of late Gothic architecture and a feature common in Scotland, but the detail is Classical. The main windows to the galleries are also mullioned and transomed, again a Gothic feature, the top row of windows are interspersed with statues of many of the British artists whose work is displayed in the museum.
Example Output:
Who designed the main façade that stretches along Cromwell Gardens?
