Please answer this: Given the following context: The Rokeby Venus (; also known as The Toilet of Venus, Venus at her Mirror, Venus and Cupid, or La Venus del espejo) is a painting by Diego Velazquez, the leading artist of the Spanish Golden Age. Completed between 1647 and 1651, and probably painted during the artist's visit to Italy, the work depicts the goddess Venus in a sensual pose, lying on a bed and looking into a mirror held by the Roman god of physical love, her son Cupid. The painting is in the National Gallery, London. Numerous works, from the ancient to the baroque, have been cited as sources of inspiration for Velazquez. The nude Venuses of the Italian painters, such as Giorgione's Sleeping Venus (c. 1510) and Titian's Venus of Urbino (1538), were the main precedents. In this work, Velazquez combined two established poses for Venus: recumbent on a couch or a bed, and gazing at a mirror. She is often described as looking at herself on the mirror, although this is physically impossible since viewers can see her face reflected in their direction. This phenomenon is known as the Venus effect. In a number of ways the painting represents a pictorial departure, through its central use of a mirror, and because it shows the body of Venus turned away from the observer of the painting.The Rokeby Venus is the only surviving female nude by Velazquez. Nudes were extremely rare in seventeenth-century Spanish art, which was policed actively by members of the Spanish Inquisition. Despite this, nudes by foreign artists were keenly collected by the court circle, and this painting was hung in the houses of Spanish courtiers until 1813, when it was brought to England to hang in Rokeby Park, Yorkshire. In 1906, the painting was purchased by National Art Collections Fund for the National Gallery, London. Although it was attacked and badly damaged in 1914 by the suffragette Mary Richardson, it soon was fully restored and returned to display. answer the following question: What is the full name of the artist that had his painting hung in the houses of Spanish courtiers until 1813?

Answer: Diego Velazquez

Problem: Given the following context: By the time Etty exhibited Musidora, the theme was becoming something of a cliche, such that by 1850 it was described by The Literary Gazette as "a favourite subject for a dip of the brush". As interest in studies of Musidora waned, its role as a pretext for nude paintings by English artists was replaced by Lady Godiva, who had become a topic of increased interest owing to Alfred, Lord Tennyson's poem Godiva. After the death of William Wordsworth in 1850, James Thomson ceased to be a major influence on writers. From the 1870s his popularity with readers waned, and by the end of the 20th century his works other than Rule, Britannia! were little known.When Etty died in 1849, despite having worked and exhibited until his death, he was still regarded by many as a pornographer. Charles Robert Leslie observed shortly after Etty's death that "[Etty] himself, thinking and meaning no evil, was not aware of the manner in which his works were regarded by grosser minds". Interest in him declined as new movements came to characterise painting in Britain, and by the end of the 19th century the value of his paintings had fallen. It is likely that the composition and style of John Everett Millais's controversial The Knight Errant was influenced by Musidora, but other than Millais, and Etty's admirer and imitator William Edward Frost, few other artists were directly influenced by Etty's work. In 1882 Vanity Fair commented on Musidora that "I know only too well how the rough and his female companion behave in front of pictures such as Etty's bather. I have seen the gangs of workmen strolling round, and I know that their artistic interest in studies of the nude is emphatically embarrassing." By the early 20th century Victorian styles of art and literature fell dramatically out of fashion in Britain, and by 1915 the word "Victorian" had become a derogatory term. Frederick Mentone's The Human Form in Art (1944) was one of the few 20th-century academic works to favourably view Musidora. answer the following question: What was the last name of Etty's admirer?

A: Frost

Q: Given the following context: Jackson explored genres including pop, soul, rhythm and blues, funk, rock, disco, post-disco, dance-pop and new jack swing. Steve Huey of AllMusic wrote that Thriller refined the strengths of Off the Wall; the dance and rock tracks were more aggressive, while the pop tunes and ballads were softer and more soulful. Its tracks included the ballads "The Lady in My Life", "Human Nature", and "The Girl Is Mine", the funk pieces "Billie Jean" and "Wanna Be Startin' Somethin'", and the disco set "Baby Be Mine" and "P.Y.T. (Pretty Young Thing)".With Off the Wall, Jackson's "vocabulary of grunts, squeals, hiccups, moans, and asides" vividly showed the singer's maturation into an adult, Robert Christgau wrote in Christgau's Record Guide: Rock Albums of the Seventies (1981). The album's title track suggested to the critic a parallel between Jackson and Stevie Wonder's "oddball" music personas: "Since childhood his main contact with the real world has been on stage and in bed." With Thriller, Christopher Connelly of Rolling Stone commented that Jackson developed his long association with the subliminal theme of paranoia and darker imagery. AllMusic's Stephen Thomas Erlewine noted this on the songs "Billie Jean" and "Wanna Be Startin' Somethin'". In "Billie Jean", Jackson depicts an obsessive fan who alleges he has fathered her child, and in "Wanna Be Startin' Somethin'" he argues against gossip and the media. "Beat It" decried gang violence in a homage to West Side Story, and was Jackson's first successful rock cross-over piece, according to Huey. He also observed that the title track "Thriller" began Jackson's interest with the theme of the supernatural, a topic he revisited in subsequent years. In 1985, Jackson co-wrote the charity anthem "We Are the World"; humanitarian themes later became a recurring theme in his lyrics and public persona. answer the following question: What is the name of the person that created the track Billie Jean?
A:
Jackson
