Input: Read this: According to John Everett-Heath, the author of Oxford Concise Dictionary of World Place Names, Hyderabad means "Haydar's city" or "lion city", from haydar (lion) and abad (city). It was named to honour the Caliph Ali Ibn Abi Talib, who was also known as Haydar because of his lion-like valour in battles. Andrew Petersen, a scholar of Islamic architecture, says the city was originally called Baghnagar (city of gardens). One popular theory suggests that Muhammad Quli Qutb Shah, the founder of the city, named it "Bhagyanagar" or "Bhagnagar" after Bhagmati, a local nautch (dancing) girl with whom he had fallen in love. She converted to Islam and adopted the title Hyder Mahal. The city was renamed Hyderabad in her honour. According to another source, the city was named after Haidar, the son of Quli Qutb Shah.
Question: Hyderabad was named in honor of someone, who was it?

Output: Caliph Ali Ibn Abi Talib

Input: Read this: Although the doctrine of Mary's Immaculate Conception appears only later among Latin (and particularly Frankish) theologians, it became ever more manifest among Byzantine theologians reliant on Gregory Nazianzen's Mariology in the Medieval or Byzantine East. Although hymnographers and scholars, like the Emperor Justinian I, were accustomed to call Mary "prepurified" in their poetic and credal statements, the first point of departure for more fully commenting on Nazianzen's meaning occurs in Sophronius of Jerusalem. In other places Sophronius explains that the Theotokos was already immaculate, when she was "purified" at the Annunciation and goes so far as to note that John the Baptist is literally "holier than all 'Men' born of woman" since Mary's surpassing holiness signifies that she was holier than even John after his sanctification in utero. Sophronius' teaching is augmented and incorporated by St. John Damascene (d. 749/750). John, besides many passages wherein he extolls the Theotokos for her purification at the Annunciation, grants her the unique honor of "purifying the waters of baptism by touching them." This honor was most famously and firstly attributed to Christ, especially in the legacy of Nazianzen. As such, Nazianzen's assertion of parallel holiness between the prepurified Mary and purified Jesus of the New Testament is made even more explicit in Damascene in his discourse on Mary's holiness to also imitate Christ's baptism at the Jordan. The Damascene's hymnongraphy and De fide Orthodoxa explicitly use Mary's "pre purification" as a key to understanding her absolute holiness and unsullied human nature. In fact, Damascene (along with Nazianzen) serves as the source for nearly all subsequent promotion of Mary's complete holiness from her Conception by the "all pure seed" of Joachim and the womb "wider than heaven" of St. Ann.
Question: Who says that Mary was not immaculate at the Annunciation?

Output: unanswerable

Input: Read this: The Demilitarized Zone runs northeast of the 38th parallel; to the south, it travels west. The old Korean capital city of Kaesong, site of the armistice negotiations, originally was in pre-war South Korea, but now is part of North Korea. The United Nations Command, supported by the United States, the North Korean People's Army, and the Chinese People's Volunteers, signed the Armistice Agreement on 27 July 1953 to end the fighting. The Armistice also called upon the governments of South Korea, North Korea, China and the United States to participate in continued peace talks. The war is considered to have ended at this point, even though there was no peace treaty. North Korea nevertheless claims that it won the Korean War.
Question: What area is directly north and south of the 38th parallel?

Output: The Demilitarized Zone

Input: Read this: On the Origin of Species, published on 24 November 1859, is a work of scientific literature by Charles Darwin which is considered to be the foundation of evolutionary biology. Darwin's book introduced the scientific theory that populations evolve over the course of generations through a process of natural selection. It presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution. Darwin included evidence that he had gathered on the Beagle expedition in the 1830s and his subsequent findings from research, correspondence, and experimentation.
Question: Who wrote The Origin of Species?

Output:
Charles Darwin
