Example Input: Question: How long was Frank Pick the general manager? Passage:Through his involvement with the Design and Industries Association Holden met Frank Pick, general manager of the Underground Electric Railways Company of London (UERL). Holden at the time had no experience in designing for transport, but this would change through his collaboration with Pick. In 1923, Pick commissioned Holden to design a façade for a side entrance at Westminster Underground station. This was followed in 1924 with an appointment to design the UERL's pavilion for the British Empire Exhibition. Also in 1924, Pick commissioned Holden to design seven new stations in south London for the extension of the City and South London Railway (now part of the Northern line) from Clapham Common to Morden. The designs replaced a set by the UERL's own architect, Stanley Heaps, which Pick had found unsatisfactory. The designs reflect the simple modernist style he was using in France for the war cemeteries; double-height ticket halls are clad in plain Portland stone framing a glazed screen, each adapted to suit the street corner sites of most of the stations. The screens feature the Underground roundel made up in coloured glass panels and are divided by stone columns surmounted by capitals formed as a three-dimensional version of the roundel. Holden also advised Heaps on new façades for a number of the existing stations on the line and produced the design for a new entrance at Bond Street station on the Central London Railway.

Example Input: Question: In what modern country is Barbitanya located? Passage:Bahlul Ibn Marzuq (died 802) was born in the current term of La Puebla de Castro (Huesca), was a Vascon-Muslim, the son of a local lord named Marzuq ibn Uskara ("son of the Basque"). He rebelled in Zaragoza against the Arab-Muslim government of Al-Andalus in 798, and in 800 conquered Huesca from the Banu Salama. His rebellion carried popular support, especially after public backing by theologian Ibn al-Mughallis. The emir sent the Huesca native, general Amrus ibn Yusuf, and Zaragoza and Huesca were retaken (c. 801). Bahlul fled to Pallars where he was killed by his lieutenant Jalaf Ibn Rashid (802), who at the time held Barbitanya (Barbastro). The adventures of Bhalul were collected by the Muslim historian and geographer Ahmad ibn Umar al-Udri (1003-1085) in the popular epic poem written in Arabic known as "the archuza de Bahlul".
