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.

Q: Passage: At the beginning of December 1910 Smoller, using the name Joe Levi, visited Exchange Buildings, a small cul-de-sac that backed onto the properties of Houndsditch. He rented No. 11 Exchange Buildings; a week later Svaars rented number 9 for a month, saying he needed it for storage. The gang were unable to rent number 10, which was directly behind their target, 119 Houndsditch, the jeweller's shop owned by Henry Samuel Harris. The safe in the jeweller's was reputed to contain between 20,000 and 30,000 worth of jewellery; Harris's son later stated the total was only around 7,000. Over the next two weeks the gang brought in various pieces of necessary equipment, including a 60-foot (18.25 m) length of India rubber gas hose, a cylinder of compressed gas and a selection of tools, including diamond-tipped drills.With the exception of Gardstein, the identities of the gang members present in Houndsditch on the night of 16 December 1910 have never been confirmed. Bernard Porter, writing in the Dictionary of National Biography, considers that Sokoloff and Peters were present and, in all likelihood, were two of those who shot the policemen who interrupted their burglary. Porter opines that Peter the Painter was probably not at the property that night, while the journalist J P Eddy suggests that Svaars was among those present. Donald Rumbelow, a former policeman who wrote a history of the events, considers that those present consisted of Gardstein, Smoller, Peters and Dubof, with a second group in case the work needed to continue into the following day, which included among their number Sokolow and Svaars. Rumbelow considers a third group on standby, staying at Hoffman's lodgings, to have comprised Hoffman, Rosen and Osip Federoff, an unemployed locksmith. Rumbelow also considers that present at the eventseither as lookouts or in unknown capacitieswere Peter the Painter and Nina Vassilleva.On 16 December, working from the small yard behind 11 Exchange Buildings, the gang began to break through the back wall of the shop; number 10 had been unoccupied since 12 December. At around 10:00 that evening, returning to his home at 120 Houndsditch, Max Weil heard curious noises coming from his neighbour's property. Outside his house Weil found Police Constable Piper on his beat and informed him of the noises. Piper checked at 118 and 121 Houndsditch, where he could hear the noise, which he thought was unusual enough to investigate further. At 11:00 he knocked at the door of 11 Exchange Buildingsthe only property with a light on in the back. The door was opened in a furtive manner and Piper became suspicious immediately. So as not to rouse the man's concerns, Piper asked him "is the missus in?" The man answered in broken English that she was out, and the policeman said he would return later.

A: What is the last name of the man who knocked on the door of 11 Exchange Buildings?

Q: Passage: In 1963, Ennis Del Mar and Jack Twist are hired by Joe Aguirre to herd his sheep through the summer in the Wyoming mountains. After a night of heavy drinking, Jack makes a pass at Ennis, who is initially hesitant but eventually responds to Jack's advances. Despite Ennis' telling Jack that it was a one-time incident, they develop a passionate sexual and emotional relationship. After Jack and Ennis eventually part ways, Ennis marries his longtime fiancee Alma Beers and has two daughters with her. Jack returns the next summer seeking work, but Aguirre, who had observed Jack and Ennis on the mountain, refuses to rehire him.
Jack moves to Texas, where he meets, marries, and has a son with rodeo rider Lureen Newsome. After four years, Jack visits Ennis. Upon meeting, the two kiss passionately, and Alma inadvertently observes this. Jack broaches the subject of creating a life with Ennis on a small ranch, but Ennis, haunted by a childhood memory of the torture and murder of two men suspected of homosexual behavior, refuses. He is also unwilling to abandon his family.
Ennis and Jack continue to meet for infrequent fishing trips as their respective marriages deteriorate. Lureen abandons the rodeo, going into business with her father and expecting Jack to work in sales. Alma and Ennis eventually divorce in 1975. Upon hearing about Ennis' divorce, Jack drives to Wyoming. He suggests again that they live together, but Ennis refuses to move away from his children.
Jack finds solace with male prostitutes in Mexico. Ennis sees his family regularly until Alma finally confronts him about her knowing the true nature of his relationship with Jack. This results in a violent argument, causing Ennis to abandon his connections with Alma. Ennis meets and has a brief romantic relationship with Cassie Cartwright, a waitress.

Q: Passage: In the latter years of the 20th century the opera was a regular feature in many European cities, and was still breaking new ground; in 1990 it made its debut at the Slovak National Theatre in Bratislava. Vienna saw it for the first time in 1994, at the Vienna Volksoper, in what John Rockwell in the New York Times described as "an awkwardly updated production", though well performed. The opera had not so far proved particularly popular in the United States, where since the Met premiere of 1916, performances had been rare compared with Europe. Lyric Opera of Chicago staged it in 1966, but waited until 1998 before reviving it. In 1980 the New York City Opera mounted a production based on the 1863 edition, and staged it again in 1983 and 1986. Reviewing the 1986 production, Henahan wrote that despite the inept libretto the work was saved by the "melodic suppleness and warmth" of Bizet's score.San Diego Opera first staged the work in 1993, but it was this company's 2004 production, designed by Zandra Rhodes, that generated new levels of enthusiasm for the opera throughout the United States. In the following few years this production was shown in seven other U.S. opera houses; in October 2008 James C. Whitson, in Opera News, reported that worldwide, "between 2007 and 2009, half of all major production of the piece have been or will be ... in the U.S.". San Diego's director, Ian Campbell, suggested that his company's 2004 production was "created at a time when it seemed many U.S. opera companies were looking for a not-too-expensive production with melody, and a little off the beaten track .... [Our] Les pecheurs de perles fitted the bill.
In January 2008 the opera received its first performance in Sri Lanka, the land of its setting. The conductor, Benjamin Levy, directed a large group of singers and musicians, mostly young and local. In October 2010, after an interval of more than 120 years, the opera was reintroduced to London's Royal Opera House. Two concert performances were given using a new edition of the score, prepared by Brad Cohen after the discovery in the Bibliotheque nationale de France of Bizet's 1863 conducting score. Commenting on this performance in The Daily Telegraph, Rupert Christiansen drew attention to the "musing intimacy and quiet dignity" with which the duet was sung, as compared with more traditional macho renderings.The Metropolitan New York presented a new production of the work in 2016, the first time the opera had been performed there for nearly a hundred years.

A:
What was the name of the opera that made its debut in Bratislava in 1990?
