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 Janáček 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: The Avenue Range Station massacre was the murder of a group of Aboriginal Australians by white settlers during the Australian frontier wars. It occurred in about September 1848 at Avenue Range, a sheep station in the southeast of the Colony of South Australia.
Information is scarce about the basic facts of the massacre, including the exact date and number of victims. A contemporary account of the massacre listed nine victims – three women, two teenage girls, three infants, and an "old man blind and infirm". Another account published by Christina Smith in 1880 gave the number of victims as eleven, and specified that they belonged to the Tanganekald people. Pastoralist James Brown and his overseer, a man named Eastwood, were suspected of committing the murders in retaliation for attacks on Brown's sheep.
In January 1849, reports of the massacre reached Matthew Moorhouse, the Protector of Aborigines. He visited the district to investigate the claims, and based on his enquiries Brown was charged with the murders in March 1849. Proceedings against Brown began in June 1849 and continued in the Supreme Court of South Australia for several months, but were eventually abandoned. Some key witnesses, including Eastwood, either fled the colony or refused to cooperate with the investigation. There were also significant restrictions on the use of evidence given by Aboriginal witnesses, especially where a verdict could involve capital punishment. These legal hurdles and settler solidarity ensured the case did not go to trial, although the magistrate who committed him for trial told a friend that there was "little question of the butchery or the butcher".
Although the details of the case were known for decades after the murders, distortions of the massacre eventually appeared in print and were embellished by local white and Aboriginal historians. Two key aspects of these later accounts were that Brown poisoned rather than shot the victims, and that he had undertaken an epic horse ride to Adelaide to establish an alibi. Historians Robert Foster, Rick Hosking and Amanda Nettelbeck contend that these "pioneer legend" alterations downplayed the seriousness of the crime.

Output: The details of the case were known for decades after what murders?


Input: Consider Input: Passage: Three neighborhood teens and childhood friends, Alex, Tuck, and Munch, are upset by the fact that their neighborhood, Mulberry Woods, Nevada, is going to be demolished, allegedly for a new highway construction project, and they all have to move away because of it.
While at Tuck's house, their phones start to glitch out, displaying seemingly random graphical patterns. They soon find out, through Munch, that the patterns are actually a map to a spot in the desert 17.6 miles away. They decide to go to the desert on their bikes and disguise it as a sleepover, recording the experience on various cameras because it's their last night together.
Tuck, Alex, and Munch eventually make it to the desert, and they follow the map to a dusty, rusted object under an electrical tower. Tuck, confused, decides to abruptly call it off when the object starts to copy Alex's ringtone, and they follow another map to a barn. There the object telekinetically starts to repair itself, and the boys find it contains an alien that can answer questions with "Yes" or "No" answers, from which they learn it is from outer space, has crash landed after being shot down by an unknown force, and is seriously injured.
They follow another map to a pawn shop, where the object further repairs itself, allowing the alien to reveal itself, using Alex's phone camera to "see" and befriend the three. While in an alley, they decide to name the alien "Echo." Looking for more parts to repair Echo, they again follow another map to a house where Emma, a girl who goes to their high school, lives and finds out about Echo. Emma soon joins the team, as they go to a bar, then an arcade, and she finds out the object Echo is in is a key to a spaceship hidden in Mulberry Woods.


Output: Who names the alien?
