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.
One example: Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs.
Solution is here: Who believes Fagin's gang make wallets and handkerchiefs?.
Explanation: This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.

Now, solve this: Passage: In August 1560, parliament assembled in Edinburgh and legislated that the Scottish church would be Protestant, the Pope would have no authority and that the Catholic mass was illegal. Scottish cathedrals now survived only if they were used as parish churches and as Elgin had been fully served by the Kirk of St Giles, its cathedral was abandoned. An act of parliament passed on 14 February 1567 authorised Regent Lord James Stewart's Privy Council to order the removal of the lead from the roofs of both Elgin and Aberdeen cathedrals, to be sold for the upkeep of his army, but the overladen ship that was intended to take the cargo to Holland capsized and sank in Aberdeen harbour. In 1615, John Taylor, the 'Water Poet', described Elgin Cathedral as "a faire and beautiful church with three steeples, the walls of it and the steeples all yet standing; but the roofes, windowes and many marble monuments and tombes of honourable and worthie personages all broken and defaced".Decay had set in and the roof of the eastern limb collapsed during a gale on 4 December 1637. In 1640 the General Assembly ordered Gilbert Ross, the minister of St Giles kirk, to remove the rood screen which still partitioned the choir and presbytery from the nave. Ross was assisted in this by the Lairds of Innes and Brodie who chopped it up for firewood. It is believed that the destruction of the great west window was caused by Oliver Cromwell's soldiers sometime between 1650 and 1660.At some point, the cathedral grounds had become the burial ground for Elgin. The town council arranged for the boundary wall to be repaired in 1685 but significantly, the council ordered that the stones from the cathedral should not be used for that purpose. Although the building was becoming increasingly unstable the chapterhouse continued to be used for meetings of the Incorporated Trades from 1671 to 1676 and then again from 1701 to around 1731. No attempt was made to stabilise the structure and on Easter Sunday 1711 the central tower gave way, demolishing the nave. Following this collapse, the "quarrying" of the cathedral's stonework for local projects began. Many artists visited Elgin to sketch the ruins, and it is from their work that the slow but continuing ruination can be observed. By the closing years of the 18th century, travelers to Elgin began to visit the ruin, and pamphlets giving the history of the cathedral were prepared for those early tourists. In 1773 Samuel Johnson recorded, "a paper was put into our hands, which deduced from sufficient authorities the history of this venerable ruin.".
Solution:
What structure did the council order the stones from the cathedral not be used for?
