Example Input: Question: What country was Methodios Fouyias born in? Passage:Methodios Fouyias (; 12 September 1924 in Corinth – 7 July 2006) served as Greek Orthodox Archbishop of Thyateira and Great Britain (concomitantly apokrisiarios of the Ecumenical Patriarch to the Archbishop of Canterbury) from 1979 to 1988. After studies in the Theological Faculty of the University of Athens and parochial responsibilities in Munich, he served in various positions within the Patriarchate of Alexandria culminating in that of Metropolitan of Axum covering Ethiopia and the Horn of Africa. Fouiyas' studies and encounters led to a favourable understanding of the Church of England which he saw in some respects as a continuator of the Saxon Church before the Norman Conquest, the Gregorian Reform and most importantly the East–West Schism of 1054. He was thus seen as the ideal candidate for the post of archbishop in London. Several years experience however of deepening division within Anglicanism led him openly to suggest (in an article in The Times) that the road to unity for Anglicans lay in submission to the discipline of the Roman Catholic church. As his post involved close relations with Lambeth it was judged expedient that he should be recalled. Methodios assumed the title of Pisidia and continued his studies (notably on Bessarion) in Greece.

Example Input: Question: What was John Holt's career? Passage:Youth activism as a social phenomenon in the United States truly became defined in the mid- to late-nineteenth century when young people began forming labor strikes in response to their working conditions, wages, and hours. Mary Harris "Mother" Jones organized the first youth activism in the U.S., marching 100,000 child miners from the coal mines of Pennsylvania to the U.S. Capitol in Washington, D.C. in 1908. Youth newspaper carriers soon followed. These actions isolated youths' interests in the popular media of the times, and separated young people from their contemporary adult labor counterparts. This separation continued through the 1930s, when the American Youth Congress presented a "Bill of Youth Rights" to the US Congress. Their actions were indicative of a growing student movement present throughout the US from the 1920s through the early 1940s. The 1950s saw the Student Nonviolent Coordinating Committee bring young people into larger movements for civil rights. All the way back in 1959, Rev. Dr. Martin Luther King, Jr. engaged youth activists in protesting against Bull Connor's racist law enforcement practices in Birmingham, Alabama. The youth activism of Tom Hayden, Keith Hefner and other 1960s youth laid a powerful precedent for modern youth activism. John Holt, Myles Horton and Paulo Freire were important in this period. Youthful life and expression defined this era.

Example Input: Question: What country was Medina part of in 844? Passage:Hasan was born in Medina around 844. Hasan's father was a descendant of Husayn ibn Ali, the grandson of Muhammad and third Shi'a Imam, via his eldest son Zayn al-Abidin, while his mother was an unnamed Khurasani slave. When Hasan ibn Zayd, a descendant of Husayn's brother Hasan, established his rule over Tabaristan in the 860s, Hasan joined him there. However, he eventually fell out with Hasan ibn Zayd's brother and successor, Muhammad ibn Zayd, who distrusted him. Hasan left Tabaristan and tried to set up a realm of his own in the provinces further east. To this end, he allied himself with the ruler of Khurasan, Muhammad ibn Abdallah al-Khujistani, who was an enemy of Muhammad ibn Zayd. Soon, however, al-Khujistani too came to distrust him and had him imprisoned and scourged, as a result of which he lost his hearing and received the sobriquet al-Utrush ("the Deaf"), by which he is known.
