Input: Consider Input: Passage: The attribution of the panel reflects the progression and trends of 19th and 20th-century scholarship on Early Netherlandish art. It is now thought to have been completed c. 1438–40, but there are still arguments for dates as early as 1424–29. As with the pages ascribed to Hand G in the Turin-Milan Hours manuscript, the panel was attributed to Jan's brother Hubert van Eyck in the 1875 Gemäldegalerie catalogue, and by a 1911 claim by art historian Georges Hulin de Loo. This is no longer considered credible and Hubert, today, is credited with very few works. By 1912 the painting had been definitively attributed to Jan in the museum catalogue.Attempts to date it have undergone similar shifts of opinion. In the 19th century the panel was believed to be an early work by Jan completed as early as c. 1410, although this view changed as scholarship progressed. In the early 20th century, Ludwig von Baldass placed it around 1424–29, then for a long period it was seen as originating from the early 1430s. Erwin Panofsky provided the first detailed treatise on the work and placed it around 1432–34. However, following research from Meyer Schapiro, he revised his opinion to the late 1430s in the 1953 edition of his Early Netherlandish Painting. A 1970s comparative study of van Eyck's 1437 Saint Barbara concluded that Madonna in the Church was completed after c. 1437. In the 1990s, Otto Pächt judged the work as probably a late van Eyck, given the similar treatment of an interior in the 1434 Arnolfini Portrait. In the early 21st century, Jeffrey Chipps Smith and John Oliver Hand placed it between 1426 and 1428, claiming it as perhaps the earliest extant signed work confirmed as by Jan. 
Question: What is the full name of the person who is credited with very few works?

Output: Hubert van Eyck.


Input: Consider Input: 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?

Output: Perry.


Input: Consider Input: Passage: Sixteen days after his death, Wallace's double-disc second album was released as planned with the shortened title of Life After Death and hit No. 1 on the Billboard 200 charts, after making a premature appearance at No. 176 due to street-date violations. The record album featured a much wider range of guests and producers than its predecessor. It gained strong reviews and in 2000 was certified Diamond, the highest RIAA certification awarded to a solo hip hop album.
Its lead single, "Hypnotize", was the last music video recording in which Wallace would participate. His biggest chart success was with its follow-up "Mo Money Mo Problems", featuring Sean Combs (under the rap alias "Puff Daddy") and Mase. Both singles reached No. 1 in the Hot 100, making Wallace the first artist to achieve this feat posthumously. The third single, "Sky's The Limit", featuring the band 112, was noted for its use of children in the music video, directed by Spike Jonze, who were used to portray Wallace and his contemporaries, including Combs, Lil' Kim, and Busta Rhymes. Wallace was named Artist of the Year and "Hypnotize" Single of the Year by Spin magazine in December 1997.In mid-1997, Combs released his debut album, No Way Out, which featured Wallace on five songs, notably on the third single "Victory". The most prominent single from the record album was "I'll Be Missing You", featuring Combs, Faith Evans and 112, which was dedicated to Wallace's memory. At the 1998 Grammy Awards, Life After Death and its first two singles received nominations in the rap category. The album award was won by Combs's No Way Out and "I'll Be Missing You" won the award in the category of Best Rap Performance By A Duo Or Group in which "Mo Money Mo Problems" was nominated.In 1996, Wallace started putting together a hip hop supergroup, the Commission, which consisted himself, Jay-Z, Lil' Cease, Combs, and Charli Baltimore. The Commission was mentioned by Wallace in the lyrics of "What's Beef" on Life After Death and "Victory" from No Way Out, but a Commission album was never completed. A track on Duets: The Final Chapter, "Whatchu Want (The Commission)", featuring Jay-Z, was based on the group. 
Question: What is the name of the supergroup that never completed an album?


Output: The Commission.
