[Q]: Passage: Monteverdi was an established court composer in the service of Duke Vincenzo Gonzaga in Mantua when he wrote his first operas, L'Orfeo and L'Arianna, in the years 1606–08. After falling out with Vincenzo's successor, Duke Francesco Gonzaga, Monteverdi moved to Venice in 1613 and became director of music at St Mark's Basilica, a position he held for the rest of his life. Alongside his steady output of madrigals and church music, Monteverdi continued to compose works for the stage, though not actual operas. He wrote several ballets and, for the Venice carnival of 1624–25, Il combattimento di Tancredi e Clorinda ("The Battle of Tancred and Clorinda"), a hybrid work with some characteristics of ballet, opera and oratorio.
In 1637 fully-fledged opera came to Venice with the opening of the Teatro San Cassiano. Sponsored by the wealthy Tron family, this theatre was the first in the world specifically devoted to opera. The theatre's inaugural performance, on 6 March 1637, was L'Andromeda by Francesco Manelli and Benedetto Ferrari. This work was received with great enthusiasm, as was the same pair's La Maga fulminata the following year. In rapid succession three more opera houses opened in the city, as the ruling families of the Republic sought to express their wealth and status by investing in the new musical fashion. At first, Monteverdi remained aloof from these activities, perhaps on account of his age (he was over 70), or perhaps through the dignity of his office as maestro di capella at St. Mark's. Nevertheless, an unidentified contemporary, commenting on Monteverdi's silence, opined that the maestro might yet produce an opera for Venice: "God willing, one of these nights he too will step onto the stage." This remark proved prescient; Monteverdi's first public contribution to Venetian opera came in the 1639–40 carnival season, a revival of his L'Arianna at the Teatro San Moisè.L'Arianna was followed in rapid succession by three brand new Monteverdi operas, of which Il ritorno was the first. The second, Le nozze d' Enea in Lavinia ("The Marriage of Aeneas to Lavinia"), was performed during the 1640–41 carnival; Monteverdi's music is lost, but a copy of the libretto, of unknown authorship, survives. The last of the three, written for the 1642–43 carnival, was L'incoronazione di Poppea ("The Coronation of Poppea"), performed shortly before the composer's death in 1643. 
Question: Where did Monteverdi perform his first opera?
[A]: Teatro San Moisè.


[Q]: Passage: Katheryn Elizabeth Hudson (born October 25, 1984), known professionally as Katy Perry, is an American singer, songwriter, and television judge. After singing in church during her childhood, she pursued a career in gospel music as a teenager. Perry signed with Red Hill Records and released her debut studio album Katy Hudson under her birth name in 2001, which was commercially unsuccessful. She moved to Los Angeles the following year to venture into secular music after Red Hill ceased operations and she subsequently began working with producers Glen Ballard, Dr. Luke, and Max Martin. After adopting the stage name Katy Perry and being dropped by The Island Def Jam Music Group and Columbia Records, she signed a recording contract with Capitol Records in April 2007.
Perry rose to fame in 2008 with the release of her second album, a pop rock record titled One of the Boys, and its singles "I Kissed a Girl" and "Hot n Cold". The former track also sparked controversy for its sapphic themes. Her third album, Teenage Dream (2010), ventured into disco, and was her first album to top the U.S. Billboard 200. It topped the U.S. Billboard Hot 100 with the singles "California Gurls", "Teenage Dream", "Firework", "E.T.", and "Last Friday Night (T.G.I.F.)", while "The One That Got Away" reached number three on the chart. The album became the first by a female artist to produce five number-one songs in the U.S., and the second overall after Michael Jackson's album Bad. In March 2012, she re-issued the album as Teenage Dream: The Complete Confection, which produced the songs "Part of Me" and "Wide Awake". Her fourth album, Prism (2013), was her second to peak atop the U.S. charts. It is influenced by pop and dance, and she became the first artist with multiple videos to reach one billion views on Vevo with the videos for its songs "Roar" and "Dark Horse". Her fifth album, Witness (2017), delved into electropop and became her third album to reach number one in the U.S. "Chained to the Rhythm" was the album's most successful single, breaking Spotify's record at the time for most first-day streams for a song by a female artist.
Perry has received various awards, including four Guinness World Records, five American Music Awards, a Brit Award, and a Juno Award, and has been included in the annual Forbes lists of highest-earning women in music from 2011–2018. Her estimated net worth as of 2016 is $125 million. She is one of the best-selling music artists of all time, having sold more than 100 million records globally throughout her career. In film, she released an autobiographical documentary titled Katy Perry: Part of Me in 2012, and voiced Smurfette in the 2011 film The Smurfs and its sequel in 2013. Perry also began serving as a judge on American Idol in 2018. 
Question: What is the better-known last name of the person who signed a recording contract with Capitol Records in April 2007?
[A]: Perry.


[Q]: Passage: Stereolab introduced easy-listening elements into their sound with the EP Space Age Bachelor Pad Music, released in March 1993. The work raised the band's profile and landed them a major-label American record deal with Elektra Records. Their first album under Elektra, Transient Random-Noise Bursts with Announcements (August 1993), was an underground success in both the US and the UK. Mark Jenkins commented in Washington Post that with the album, Stereolab "continues the glorious drones of [their] indie work, giving celestial sweep to [their] garage-rock organ pumping and rhythm-guitar strumming". In the UK, the album was released on Duophonic Ultra High Frequency Disks, which is responsible for domestic releases of Stereolab's major albums.In January 1994, Stereolab achieved their first chart entry when the 1993 EP Jenny Ondioline, entered at number 75 on the UK Singles Chart. (Over the next three years, four more releases by the band would appear on this chart, ending with the EP Miss Modular in 1997.) Their third album, Mars Audiac Quintet, was released in August 1994. The album contains the single "Ping Pong", which gained press coverage for its allegedly explicit Marxist lyrics. The band focused more on pop and less on rock, resulting in what AllMusic described as "what may be the group's most accessible, tightly-written album". It was the last album to feature O'Hagan as a full-time member. He would continue to make guest appearances on later releases. The group issued an EP titled Music for the Amorphous Body Study Center in April 1995. The EP was their musical contribution to an interactive art exhibit put on in collaboration with New York City artist Charles Long. Their second compilation of rarities, titled Refried Ectoplasm (Switched On, Vol. 2), was released in July 1995. 
Question: What EP was their musical contribution to an interactive art exhibit?
[A]:
Music for the Amorphous Body Study Center.
