Detailed Instructions: In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Problem:Passage: Despite William Bruce's fall from political favour, and his intermittent imprisonment, he continued to practice. During the 1690s he completed Hill of Tarvit (1696), Craighall (1697–99) in Fife, and Craigiehall (1699) near Edinburgh. The latter, built for the Marquess of Annandale, still stands, and is used as the British Army's Scottish headquarters. From 1698 he was working on a new house for the young Charles Hope, later first Earl of Hopetoun. Hopetoun House, near Edinburgh, was completed in 1702, and represents Bruce's grandest country house design. The master mason was again Thomas Bauchop, and the inspiration was again Anglo-Dutch, with French rustication. The bulk of Bruce's work is now obscured by 18th-century remodelling, carried out by William Adam. Bruce was commissioned again by Hopetoun in 1708, to build a private aisle at Abercorn Kirk. The Hopetoun Loft overlooks the interior of the kirk, and connects to a retiring room with an oval "squint" giving a view of the pulpit.In 1702 Bruce was commissioned by the burgesses of Stirling to design a new tolbooth for the town. Bruce provided only sketch plans, which were executed by local masons between 1703 and 1705. Bruce's last country houses were Harden House (now known as Mertoun House), built for the Scotts in the Borders, and his smallest house, Auchendinny in Midlothian. His final work, in around 1710, was for Nairne House, for the Jacobite Lord Nairne. The house was not completed until two years after Bruce's death, and the extent of his involvement is unclear. Nairne House was demolished in 1760, although the cupola was retained and installed on the roof of the King James VI Hospital in nearby Perth.
