Task: Question Generation
Input (English): Passage: Holkham was built by 1st Earl of Leicester, Thomas Coke, who was born in 1697. A cultivated and wealthy man, Coke made the Grand Tour in his youth and was away from England for six years between 1712 and 1718. It is likely he met both Burlington—the aristocratic architect at the forefront of the Palladian revival movement in England—and William Kent in Italy in 1715, and that in the home of Palladianism the idea of the mansion at Holkham was conceived. Coke returned to England, not only with a newly acquired library, but also an art and sculpture collection with which to furnish his planned new mansion. However, after his return, he lived a feckless life, preoccupying himself with drinking, gambling and hunting, and being a leading supporter of cockfighting.  He made a disastrous investment in the South Sea Company and when the South Sea Bubble burst in 1720, the resultant losses delayed the building of Coke's planned new country estate for over ten years. Coke, who had been made Earl of Leicester in 1744, died in 1759—five years before the completion of Holkham—having never fully recovered his financial losses. Thomas's wife, Lady Margaret Tufton, Countess of Leicester (1700–1775), would oversee the finishing and furnishing of the house.Although Colen Campbell was employed by Thomas Coke in the early 1720s, the oldest existing working and construction plans for Holkham were drawn by Matthew Brettingham, under the supervision of Thomas Coke, in 1726. These followed the guidelines and ideals for the house as defined by Kent and Burlington. The Palladian revival style chosen was at this time making its return in England. The style made a brief appearance in England before the Civil War, when it was introduced by Inigo Jones. However, following the Restoration it was replaced in popular favour by the Baroque style. The "Palladian revival", popular in the 18th century, was loosely based on the appearance of the works of the 16th-century Italian architect Andrea Palladio. However it did not adhere to Palladio's strict rules of proportion. The style eventually evolved into what is generally referred to as Georgian, still popular in England today. It was the chosen style for numerous houses in both town and country, although Holkham is exceptional for both its severity of design and for being closer than most in its adherence to Palladio's ideals.
