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 20112018. 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?
Perry.

Passage: William Etty (10 March 1787 13 November 1849) was an English artist best known for his history paintings containing nude figures. He was the first significant British painter of nudes and still lifes. Born in York, he left school at the age of 12 to become an apprentice printer in Hull. He completed his apprenticeship seven years later and moved to London, where in 1807 he joined the Royal Academy Schools. There he studied under Thomas Lawrence and trained by copying works by other artists. Etty earned respect at the Royal Academy of Arts for his ability to paint realistic flesh tones, but had little commercial or critical success in his first few years in London.
Etty's Cleopatra's Arrival in Cilicia, painted in 1821, featured numerous nudes and was exhibited to great acclaim. Its success prompted several further depictions of historical scenes with nudes. All but one of the works he exhibited at the Royal Academy in the 1820s contained at least one nude figure, and he acquired a reputation for indecency. Despite this, he was commercially successful and critically acclaimed, and in 1828 was elected a Royal Academician, at the time the highest honour available to an artist. Although he was one of the most respected artists in the country he continued to study at life classes throughout his life, a practice considered inappropriate by his fellow artists. In the 1830s Etty began to branch out into the more lucrative but less respected field of portraiture, and later became the first English painter to paint significant still lifes. He continued to paint both male and female nudes, which caused severe criticism and condemnation from some elements of the press.
An extremely shy man, Etty rarely socialised and never married. From 1824 until his death he lived with his niece Betsy (Elizabeth Etty). Even in London he retained a keen interest in his native York, and was instrumental in the establishment of the town's first art school and the campaign to preserve York city walls. While he never formally converted from his Methodist faith, he was deeply attached to the Roman Catholic Church and was one of the few non-Catholics to attend the 1838 opening of Augustus Pugin's chapel for St Mary's College, Oscott, at that time England's most important Roman Catholic building.
Question: What church was the artist who was the first significant painter of nudes deeply attached to?
Roman Catholic Church.

Passage: Diorama is the fourth studio album by Australian alternative rock band Silverchair, released on 31 March 2002 by Atlantic/Eleven. It won the 2002 ARIA Music Award for Best Group and Best Rock Album. The album was co-produced by Daniel Johns and David Bottrill. While Bottrill had worked on albums for a variety of other bands, Diorama marked the first production credit for lead singer Johns.
Johns wrote most of the album at the piano instead of his usual guitar, while the band took a 12-month break following their previous studio album, Neon Ballroom. Silverchair worked with composer Van Dyke Parks on Diorama; the album contains numerous orchestral arrangements and power ballads, a change from the post-grunge music typical of their earlier work, but consistent with the band's previous orchestrations on Neon Ballroom. The album's title refers to "a world within a world". Five singles were released: "The Greatest View", "Without You", "Luv Your Life", "Across the Night" and "After All These Years". All except "After All These Years", a promotional single, appeared on the Australian singles chart.
Diorama was successful in the charts but was not as well received by critics as the band's earlier albums. It reached number one on the Australian Recording Industry Association (ARIA) Albums Chart and received a rating of 71 (out of 100) on review aggregator Metacritic. It was certified triple-platinum by ARIA, selling in excess of 210,000 copies, and won five ARIA Awards in 2002. Diorama was nominated for Highest Selling Album in 2003, and three songs from the album were nominated for awards over the two years.
Question: What is the full name of Silverchair's lead singer?
Daniel Johns.
