Input: Read this: The great Navicella mosaic (1305–1313) in the atrium of the Old St. Peter's is attributed to Giotto di Bondone. The giant mosaic, commissioned by Cardinal Jacopo Stefaneschi, was originally situated on the eastern porch of the old basilica and occupied the whole wall above the entrance arcade facing the courtyard. It depicted St. Peter walking on the waters. This extraordinary work was mainly destroyed during the construction of the new St. Peter's in the 17th century. Navicella means "little ship" referring to the large boat which dominated the scene, and whose sail, filled by the storm, loomed over the horizon. Such a natural representation of a seascape was known only from ancient works of art.
Question: Who created the Navicella mosaic in the Old St. Peter's church?

Output: Giotto di Bondone


Input: Read this: The best known work of fiction from the Islamic world is One Thousand and One Nights (In Persian: hezār-o-yek šab > Arabic: ʔalf-layl-at-wa-l’-layla= One thousand Night and (one) Night) or *Arabian Nights, a name invented by early Western translators, which is a compilation of folk tales from Sanskrit, Persian, and later Arabian fables. The original concept is derived from a pre-Islamic Persian prototype Hezār Afsān (Thousand Fables) that relied on particular Indian elements. It reached its final form by the 14th century; the number and type of tales have varied from one manuscript to another. All Arabian fantasy tales tend to be called Arabian Nights stories when translated into English, regardless of whether they appear in The Book of One Thousand and One Nights or not. This work has been very influential in the West since it was translated in the 18th century, first by Antoine Galland. Imitations were written, especially in France. Various characters from this epic have themselves become cultural icons in Western culture, such as Aladdin, Sinbad the Sailor and Ali Baba.
Question: Arabian nights was originally based upon what Persian work?

Output: Hezār Afsān (Thousand Fables)


Input: Read this: Arsenal appointed Herbert Chapman as manager in 1925. Having already won the league twice with Huddersfield Town in 1923–24 and 1924–25 (see Seasons in English football), Chapman brought Arsenal their first period of major success. His revolutionary tactics and training, along with the signings of star players such as Alex James and Cliff Bastin, laid the foundations of the club's domination of English football in the 1930s. Under his guidance Arsenal won their first major trophies – victory in the 1930 FA Cup Final preceded two League Championships, in 1930–31 and 1932–33. In addition, Chapman was behind the 1932 renaming of the local London Underground station from "Gillespie Road" to "Arsenal", making it the only Tube station to be named specifically after a football club.
Question: What was the name of one of Arsenal's coaches prior to 1925?

Output: unanswerable


Input: Read this: Goetz set out an ambitious schedule. Universal-International became responsible for the American distribution of Rank's British productions, including such classics as David Lean's Great Expectations (1946) and Laurence Olivier's Hamlet (1948). Broadening its scope further, Universal-International branched out into the lucrative non-theatrical field, buying a majority stake in home-movie dealer Castle Films in 1947, and taking the company over entirely in 1951. For three decades, Castle would offer "highlights" reels from the Universal film library to home-movie enthusiasts and collectors. Goetz licensed Universal's pre–Universal-International film library to Jack Broeder's Realart Pictures for cinema re-release but Realart was not allowed to show the films on television.
Question: What year was David Lean's Hamlet produced?

Output:
unanswerable
