Teacher: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.
Teacher: Now, understand the problem? Solve this instance: Passage: In the early nineteenth century, the original Norman castle had been enlarged and refashioned by Henry Holland for the 1st Marquess, the 3rd Marquess's great-grandfather. The 2nd Marquess occupied the castle on visits to his extensive Glamorgan estates, during which he developed modern Cardiff and created Cardiff Docks as the outlet for coal and steel from the South Wales Valleys, but did little to the castle itself, beyond completing the 1st Marquess's work. 
The 3rd Marquess despised Holland's efforts, describing the castle as having been "the victim of every barbarism since the Renaissance", and, on his coming of age, engaged Burges to undertake rebuilding on a Wagnerian scale. Almost all of Burges's usual team were involved, including Chapple, Frame and Lonsdale, creating a building which John Newman describes in Glamorgan: The Buildings of Wales as the "most successful of all the fantasy castles of the nineteenth century."
The central block of the castle comprises the two storey banqueting hall, with the library below. Both are enormous, the former to act as a suitable reception hall where the Marquess could fulfil his civic duties, the latter to hold part of his vast library. Both include elaborate carvings and fireplaces, those in the banqueting hall depicting the castle itself in the time of Robert, Duke of Normandy, who was imprisoned there in 1126–1134. The fireplace in the library contains five figures, four representing the Greek, Egyptian, Hebrew and Assyrian alphabets, while the fifth is said to represent Bute as a Celtic monk. The figures refer to the purpose of the room and to the Marquess, a noted linguist. The decoration of these large rooms is less successful than in the smaller chambers; much was completed after Burges's death and Girouard considers that the muralist, Lonsdale, "was required to cover areas rather greater than his talents deserved."The central portion of the castle also included the Grand Staircase. Illustrated in a watercolour perspective prepared by Axel Haig, the staircase was long thought never to have been built but recent research has shown that it was constructed, only to be torn out in the 1930s, reputedly after the third Marchioness had "once slipped on its polished surface." The staircase was not universally praised in the contemporary press; the Building News writing that the design was "one of the least happy we have seen from Mr Burges's pencil...the contrasts of colour are more startling than pleasing." The Arab Room in the Herbert Tower was the last room on which Burges was working when he fell ill in 1881. Bute placed Burges's initials, together with his own and the date, in the fireplace of that room as a memorial. The room was completed by Burges's brother-in-law, Richard Popplewell Pullan.
