Task: Question Generation
Input (English): Passage: Four tower buildings fan out along the front, or eastern edge, of the parliamentary complex and are notable for the curvature of their roofs. The Tower Buildings are home to the public entrance of the Scottish Parliament and to the Main Hall which is located on the eastern side of the parliamentary complex, beneath the debating chamber.  A stone vaulted ceiling is the principal feature of the Main Hall, which has cross like representations carved into it, reminiscent of the Saltire—the national flag of Scotland. The main hall contains permanent exhibitions on the role of the Scottish Parliament, as well as public seating, a visitor information desk, a shop, lockers and a creche. Like much of the parliamentary complex, the materials used to construct the Main Hall and its vaulted ceiling include Kemnay Granite from Aberdeenshire in north east Scotland and Caithness stone which is used in much of the flooring in the buildings. Connected to the Tower Buildings in the eastern portion of the complex are the Media and Canongate Buildings, which house the IT and procurement departments of the Parliament, as well as media offices and the Scottish Parliament Information Centre (SPICe). The centrepiece of the Canongate Building is a two-storey cantilever structure, with the building connected at one end by reinforced concrete and 18 metres (60 ft) of the building suspended above ground and protruding outwards unsupported by any columns.Originally dating from 1667, Queensberry House is an example of a seventeenth century Edinburgh townhouse and contrasts with the modern architecture of the rest of the parliamentary complex. From c.1800, Queensberry House has been used as a hospital, army barracks, a refuge and a geriatric hospital.  In 1996, the geriatric hospital closed and the building was incorporated into the Scottish and Newcastle brewery, who owned the surrounding site. The building has been extensively refurbished, and returned to its original height of three storeys to provide facilities for the Presiding Officer, Deputy Presiding Officers, the Chief Executive of the Scottish Parliament and various parliamentary support staff. Internally and externally the building has been strengthened with reinforced steel and concrete. The original timber flooring has been replaced throughout with a mixture of carpet, vinyl, oak and Caithness stone.  Queensberry House also contains the Donald Dewar Room, dedicated to the founding First Minister of Scotland who died in October 2000. The room hosts the personal collection of books and other memorabilia donated to the Parliament by the family of Donald Dewar after his death.
Output (English): Which building was originally three stories?
