Definition: 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: 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 pêcheurs 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 Bibliothèque 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.

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