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 facade 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 facades 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: How tall is the Serrania de Baudo mountain chain? Passage:The Coiba Plate is a small tectonic plate (a microplate) located off the coasts south of Panama and northwestern Colombia. It is named after Coiba, the largest island of Central America, just north of the plate offshore southern Panama. It is bounded on the west by the Cocos Plate, on the south by the Malpelo Plate, on the east by the North Andes Plate, and on the north by the Panama Plate. This microplate was previously assumed to be part of the Nazca Plate, forming the northeastern tongue of the Nazca Plate together with the Malpelo Plate. Bordering the Coiba Plate on the east are the north-south striking Bahia Solano Fault and east of that, the Serrania de Baudo, an isolated mountain chain in northwestern Choco, Colombia.
