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.

Input: Consider Input: Passage: The company, retaining the title "Sadler's Wells Opera", opened at the Coliseum on 21 August 1968, with a new production of Mozart's Don Giovanni, directed by Sir John Gielgud. Though this production was not well received, the company rapidly established itself with a succession of highly praised productions of other works. Arlen died in January 1972, and was succeeded as managing director by Lord Harewood.The success of the 1968 Mastersingers was followed in the 1970s by the company's first Ring cycle, conducted by Goodall, with a new translation by Andrew Porter and designs by Ralph Koltai. The cast included Norman Bailey, Rita Hunter and Alberto Remedios. In Harewood's view, among the highlights of the first ten years at the Coliseum were the Ring, Prokofiev's War and Peace, and Richard Strauss's Salome and Der Rosenkavalier.
The company's musical director from 1970 to 1977 was Charles Mackerras. Harewood praised his exceptional versatility, with a range "from The House of the Dead to Patience." Among the operas he conducted for the company were Handel's Julius Caesar starring Janet Baker and Valerie Masterson; five Janacek operas; The Marriage of Figaro with pioneering use of 18th century performing style; Massenet's Werther; Donizetti's Mary Stuart with Baker; and Sullivan's Patience. The company took the production of the last to the Vienna Festival in 1975, along with Britten's Gloriana. Sir Charles Groves succeeded Mackerras as musical director from 1978 to 1979, but Groves was unwell and unhappy during his brief tenure. Starting in 1979, Mark Elder succeeded Groves in the post, and described Groves "immensely encouraging and supportive".A long-standing concern of Arlen and then Harewood was the need to change the company's name to reflect the fact that it was no longer based at Sadler's Wells theatre. Byam Shaw commented "The one major setback the Sadler's Wells Opera Company suffered from its transplant was that unheeding taxi drivers kept on taking their patrons up to Rosebery Avenue".Harewood considered it an elementary rule that "you must not carry the name of one theatre if you are playing in another one." Covent Garden, protective of its status, objected to the suggestion that the Sadler's Wells company should be called "The British National Opera" or "The National Opera", although neither Scottish Opera nor the Welsh National Opera opposed such a change. Eventually the British government decided the matter, and the title "English National Opera" was approved. The company's board adopted the new name in November 1974. In 1977, in response to demand for more opera productions in English provincial cities, a second company was established. It was based at Leeds in northern England, and was known as ENO North. Under Harewood's guidance, it flourished, and in 1981 it became an independent company, Opera North.

Output: What name did the company that was titled "Sadler's Wells Opera" eventually change its name to?

Input: Consider Input: Passage: Oswald and a big beagle are at a cinema watching a documentary. The documentary tells about explorers who travel place to place in their hot air balloons. Oswald is amazed by the adventures of the explorers, and therefore decides become an explorer too.
One day at a fairground, a large crowd gathers to see Oswald take off in his balloon. The balloon is a large hot water bottle and the carriage is a metal stove (with switches inside). Oswald invites the big beagle, who is in the crowd, to join him.
The big beagle, at first, declines the invitation before he shakes hands with his little friend, and releases the balloon. But as the balloon rises and one of its anchors snags away his pants, the big beagle changes his mind. He would spend the entire ride on the anchor.
Oswald's balloon rapidly ascend into the heavens. They go so fast and so high that they even reach space. Their voyage ends when they land on the planet Mars. Unfortunately for them, their balloon is wreck, and the two are left wondering if they would ever get back. They begin walking on the rocky Martian surface. On the way, they see a giant sipping soup and gobbling explosives. Because of the giant's hostile nature, Oswald and the big beagle try to flee, only to unknowingly run into the bore of a huge cannon. The cannon shoots them airborne and they land in the giant's soup bowl.
The giant is surprised to see the two visitors in his bowl. Nevertheless, he becomes obliged to gobble them as he scoops up Oswald and the big beagle with his spoon. Suddenly the giant decides to delay eating his victims. He then puts Oswald and the big beagle in a large salt shaker and then chooses to have some music played by walking guns.

Output: Where did Oswald and a big beagle land when they were shot out of a canon?

Input: Consider Input: Passage: Within a decade, the house was again found to be too small, and in 1883 a new extension, the Bachelors' Wing, was constructed to the designs of a Norfolk architect, Colonel R. W. Edis. Edis also built a new billiard room and converted the old conservatory into a bowling alley. The Prince of Wales had been impressed by one he had seen at Trentham Hall, and the alley at Sandringham was modelled on an example from Rumpelheim, Germany. In 1891, during preparations for the Prince of Wales's fiftieth birthday, a serious fire broke out when maids lit all the fires in the second-floor bedrooms to warm them in advance of the Prince's arrival. Edis was recalled to undertake rebuilding and further construction. As he had with the Bachelors' Wing, Edis tried to harmonise these additions with Humbert's house by following the original Jacobethan style, and by using matching brickwork and Ketton stone.The house was up to date in its facilities, the modern kitchens and lighting running on gas from the estate's own plant and water being supplied from the Appleton Water Tower, constructed at the highest point on the estate. The tower was designed in an Italianate style by Robert Rawlinson, and Alexandra laid the foundation stone in 1877. The Prince's efforts as a country gentleman were approved by the press of the day; a contemporary newspaper expressed a wish to "Sandringhamize Marlborough House as a landlord, agriculturist and country gentleman, the Prince sets an example which might be followed with advantage".The royal couple's developments at Sandringham were not confined to the house; over the course of their occupation, the wider estate was also transformed. Ornamental and kitchen gardens were established, employing over 100 gardeners at their peak. Many estate buildings were constructed, including cottages for staff, kennels, a school, a rectory and a staff clubhouse, the Babingley. Edward also made Sandringham one of the best sporting estates in England to provide a setting for the elaborate weekend shooting parties that became Sandringham's defining rationale. To increase the amount of daylight available during the shooting season, which ran from October to February, the Prince introduced the tradition of Sandringham Time, whereby all the clocks on the estate were set half an hour ahead of GMT. This tradition was maintained until 1936. Edward's entertaining was legendary, and the scale of the slaughter of game birds, predominantly pheasants and partridges, was colossal. The meticulously maintained game books recorded annual bags of between 6,000 and 8,000 birds in the 1870s, rising to bags of over 20,000 a year by 1900. The game larder, constructed for the storage of the carcasses, was inspired by that at Holkham Hall and was the largest in Europe.
Output: What was the name of the house where Appleton Water Tower was built?
