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.

Example Input: Passage: Hilda Rix Nicholas (née Rix, later Wright, 1 September 1884 – 3 August 1961) was an Australian artist. Hilda Rix was born in the Victorian city of Ballarat. Her father was an education administrator and poet, her mother was a musician and artist. She studied under a leading member of the Heidelberg School, Frederick McCubbin, at the National Gallery of Victoria Art School from 1902 to 1905 and was an early member of the Melbourne Society of Women Painters and Sculptors. Following the death of her father in 1907, Hilda Rix, her only sibling Elsie and her mother travelled to Europe where she undertook further study in London and then in Paris. Her teachers during the period included John Hassall, Richard Emil Miller and Théophile Steinlen.
After travelling to Tangiers in 1912, Rix held several successful exhibitions of her work, with one drawing, Grande marche, Tanger, purchased by the French government. She was one of the first Australians to paint post-impressionist landscapes, was made a member of the Société des Peintres Orientalistes Français, and had works hung in the Paris Salon first in 1911 and again in 1913. The family evacuated from France to England after the outbreak of World War I. A period of personal tragedy followed, as Rix's sister died in 1914, then her mother in 1915. In 1916 she met and married George Matson Nicholas, only to be widowed the next month when he was killed on the Western Front.
Returning to Australia in 1918, Rix Nicholas once more took up professional painting, and held an exhibition of over a hundred works at Melbourne's Guild Hall. Many sold, including In Picardy, purchased by the National Gallery of Victoria. Following a period painting in rural locations in the early 1920s, Rix Nicholas returned to Europe. A 1925 exhibition in Paris led to the sale of her work In Australia to the Musée du Luxembourg, followed by an extensive tour of her paintings around regional British art galleries. There followed representation in other exhibitions, including at the International Society of Sculptors, Painters and Gravers, and the Royal Academy of Arts, both in London. Following the inclusion of several works in the 1926 Société Nationale des Beaux-Arts Spring exhibition in Paris she was made an Associate of that organisation.
Example Output: Who was killed on the Western Front?

Example Input: Passage: As a result of the Berlin Conference of 1884-1885, the Congo Basin is claimed by King Leopold II of the Belgians, who rules the Congo Free State in personal union with the Kingdom of Belgium. The country is on the verge of bankruptcy, Leopold having borrowed huge sums of money to finance the construction of railways and other infrastructure projects. He sends his envoy Léon Rom to secure the fabled diamonds of Opar. Rom's expedition is ambushed and massacred. A tribal leader, Chief Mbonga, offers Rom the diamonds in exchange for an old enemy: Tarzan.
The man once called "Tarzan", John Clayton III, has left Africa behind and settled down in London with his American-born wife, Jane Porter. He took up his birth name and ancestral family residence as Lord Greystoke. In the eight years since returning from Africa, John's story as Tarzan has become legendary among the Victorian public, although John wants to leave that past behind. Through the British Prime Minister, John is invited by King Leopold to visit Boma and report on the development of the Congo by Belgium; he declines to participate in the perceived publicity stunt.
Example Output: What is the first name of the person who sends his envoy to secure diamonds?

Example Input: 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.
Example Output:
What was the name of the room that was completed by Burges's brother-in-law, Richard Popplewell Pullan?
