[Q]: 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?
[A]: Hubert van Eyck.


[Q]: Passage: Pogoing aside, Vicious had been involved in a notorious incident during that memorable second night of the 100 Club Punk Special. Arrested for hurling a glass at The Damned that shattered and blinded a girl in one eye, he had served time in a remand centre—and contributed to the 100 Club banning all punk bands. At a previous 100 Club gig, he had assaulted Nick Kent with a bicycle chain. Indeed, McLaren's NME telegram said that Vicious's "best credential was he gave Nick Kent what he deserved many months ago at the Hundred Club". According to a later description by McLaren, "When Sid joined he couldn't play guitar but his craziness fit into the structure of the band. He was the knight in shining armour with a giant fist." "Everyone agreed he had the look," Lydon later recalled, but musical skill was another matter. "The first rehearsals...in March of 1977 with Sid were hellish.... Sid really tried hard and rehearsed a lot". Marco Pirroni, who had performed with Vicious in Siouxsie and the Banshees, has said, "After that, it was nothing to do with music anymore. It would just be for the sensationalism and scandal of it all. Then it became the Malcolm McLaren story".Membership in the Sex Pistols had a progressively destructive effect on Vicious. As Lydon later observed, "Up to that time, Sid was absolutely childlike. Everything was fun and giggly. Suddenly he was a big pop star. Pop star status meant press, a good chance to be spotted in all the right places, adoration. That's what it all meant to Sid." Westwood had already been feeding him material, like a tome on Charles Manson, likely to encourage his worst instincts. Early in 1977, he met Nancy Spungen, an emotionally disturbed drug addict and sometime prostitute from New York. Spungen is commonly thought to be responsible for introducing Vicious to heroin, and the emotional codependency between the couple alienated Vicious from the other members of the band. Lydon later wrote, "We did everything to get rid of Nancy.... She was killing him. I was absolutely convinced this girl was on a slow suicide mission.... Only she didn't want to go alone. She wanted to take Sid with her.... She was so utterly fucked up and evil.". 
Question: What is the first name of the person who "gave Nick Kent what he deserved many months ago," according to McLaren's NME telegram?
[A]: Sid.


[Q]: Passage: The Italian composer Claudio Monteverdi (1567–1643), in addition to a large output of church music and madrigals, wrote prolifically for the stage. His theatrical works were written between 1604 and 1643 and included ten operas, of which three—L'Orfeo (1607), Il ritorno d'Ulisse in patria (1640) and L'incoronazione di Poppea (1643)—have survived with their music and librettos intact. In the case of the other seven operas, the music has disappeared almost entirely, although some of the librettos exist. The loss of these works, written during a critical period of early opera history, has been much regretted by commentators and musicologists.
Opera, as a musical and theatrical genre, began to emerge during the early part of Monteverdi's career, initially as a form of courtly entertainment. With other composers, he played a leading part in its development into the main form of public musical theatre. His first opera, L'Orfeo, written in 1607 for the Mantuan court, which employed him, was a major success. In the years that followed, at Mantua and in his later capacity as maestro di cappella (director of music) at St Mark's Basilica in Venice, Monteverdi continued to write theatrical music in various genres, including operas, dances, and intermedi (short musical interludes inserted into straight plays). Because in Monteverdi's times stage music was rarely thought to have much utility after its initial performance, much of this music vanished shortly after its creation.
Most of the available information relating to the seven lost operas has been deduced from contemporary documents, including the many letters that Monteverdi wrote. These papers provide irrefutable evidence that four of these works—L'Arianna, Andromeda, Proserpina rapita and Le nozze d'Enea con Lavinia—were completed and performed in Monteverdi's lifetime, but of their music, only the famous lament from L'Arianna and a trio from Proserpina are known to have survived. The other three lost operas—Le nozze di Tetide, La finta pazza Licori and Armida abbandonata—were abandoned by Monteverdi before completion; how much of their music was actually written is unknown. 
Question: What is the last name of the person whose first opera was written for his employer, and was a major success?
[A]:
Monteverdi.
