Task: Question Generation
Input (English): Passage: Holkham Hall ( or )  is an 18th-century country house located adjacent to the village of Holkham, Norfolk, England. The house was constructed in the Palladian style for The 1st Earl of Leicester (fifth creation) by the architect William Kent, aided by the architect and aristocrat Lord Burlington.
Holkham Hall is one of England's finest examples of the Palladian revival style of architecture, and the severity of its design is closer to Palladio's ideals than many of the other numerous Palladian style houses of the period. The Holkham Estate was built up by Sir Edward Coke, the founder of his family fortune. He bought Neales manor in 1609, though never lived there, and many other purchases of land in Norfolk to endow to his six sons. His fourth son, John, inherited the land and married heiress Meriel Wheatley in 1612. They made Hill Hall their home and by 1659 John had complete ownership of all three Holkham manors. It is the ancestral home of the Coke family, the Earls of Leicester of Holkham.
The interior of the hall is opulently, but by the standards of the day, simply decorated and furnished. Ornament is used with such restraint that it was possible to decorate both private and state rooms in the same style, without oppressing the former. The principal entrance is through the Marble Hall, which is in fact made of pink Derbyshire alabaster; this leads to the piano nobile, or the first floor, and state rooms. The most impressive of these rooms is the Saloon, which has walls lined with red velvet. Each of the major state rooms is symmetrical in its layout and design; in some rooms, false doors are necessary to fully achieve this balanced effect.
Output (English): What is the name of the building that uses false doors in some rooms?
