instruction:
In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
question:
Passage: The Annunciation draws heavily on van der Weyden's 1430s Louvre Annunciation, his c. 1455  Saint Columba altarpiece, and the Clugny Annunciation (c. 1465–75), which is attributed to either van der Weyden or Memling. Memling almost certainly was apprenticed to van der Weyden in Brussels until setting up his own workshop in Bruges sometime after 1465. Memling's Annunciation is more innovative, with motifs such as the attendant angels that were absent in the earlier paintings. According to Till-Holger Borchert, not only was Memling familiar with van der Weyden's motifs and compositions, but he might have assisted with the underdrawing in van der Weyden's workshop. The shutters on the right are copied from the Louvre panel, the knotted curtain appears in the Columba triptych's "Annunciation".A sense of movement is conveyed throughout. The trailing edges of Gabriel's garment fall outside the pictorial space, indicating his arrival. The Virgin's "serpentine" pose, with attendant angels supporting her, adds to the sense of flow. Memling's use of color achieves a startling effect. The traditional rays of light are replaced with light color indicators; the white clothes rendered in "icy" blue, the angel to the right in yellow patches seems "bleached by light", the left-hand angel appears to be steeped in shadow, dressed in clothes of lavender and bearing deep green wings. The effect is iridescent, according to Blum, who writes, "this shimmering surface gives [the figures] an unearthly quality, separating them from the more believable world of the bedchamber." The effect deviates from the pure naturalism and realism which typifies Early Netherlandish art, causing a "startling" juxtaposition, an effect that is "unsteadying" and contradictory.
answer:
What is the name of the person who might have assisted with the underdrawing in Van der Weyden's workshop?


question:
Passage: Radiohead began work on their ninth studio album in September 2014, joined again by Godrich. In 2015 they resumed work in the La Fabrique studio near Saint-Rémy-de-Provence, France. The sessions were marred by the death of Godrich's father, and Yorke's separation from his wife, Rachel Owen, who died of cancer several months after the album's completion. In the same year, Yorke contributed a soundtrack, Subterranea, to The Panic Office, an installation of Radiohead artwork in Sydney, Australia, and Junun, a collaboration between Greenwood, Godrich, Israeli composer Shye Ben Tzur and Indian musicians, was released, accompanied by a documentary directed by Anderson. On Christmas Day 2015, Radiohead released a new song, "Spectre", on the audio streaming site SoundCloud. It had been commissioned for the 2015 James Bond film Spectre, but was rejected by the film producers as "too dark".Radiohead's ninth studio album, A Moon Shaped Pool, was released in May 2016 on Radiohead's website and online music stores, followed by retail versions in June via XL Recordings. It was promoted with music videos for the singles "Burn the Witch" and "Daydreaming", the latter directed by Anderson. The album includes several songs written years earlier, including "True Love Waits", and strings and choral vocals arranged by Jonny Greenwood and performed the London Contemporary Orchestra. It was Radiohead's sixth UK number-one album and reached number three in the US. It was the fifth Radiohead album nominated for the Mercury Prize, making Radiohead the most shortlisted act in the award's history, and was nominated for Best Alternative Music Album and Best Rock Song (for "Burn the Witch") at the 59th Annual Grammy Awards. It appeared on several publications' lists of the best albums of the year.
answer:
What is the name of the song that had a music video directed by Anderson?


question:
Passage: William Etty (1787–1849), the seventh son of a York baker and miller, had originally been an apprentice printer in Hull, but on completing his seven-year apprenticeship in 1805 moved to London to become an artist. In January 1807 he was admitted to the Royal Academy Schools as a probationer, and in July of that year became a student of renowned portrait painter Thomas Lawrence, studying under him for a year.Strongly influenced by the works of Titian and Rubens, Etty became famous for painting nude figures in biblical, literary and mythological settings. He became well-respected for his ability to capture flesh tones accurately in painting, and for his fascination with contrasts in skin tones. Many of his peers greatly admired his work, and in February 1828 he defeated John Constable by 18 votes to five to become a full Royal Academician, at the time the highest honour available to an artist.Between 1820 and 1829 Etty exhibited 15 paintings, of which 14 depicted nude figures. While some nude paintings by foreign artists existed in private collections in England, the country had no tradition of nude painting and the display and distribution of nude material to the public had been suppressed since the 1787 Proclamation for the Discouragement of Vice.Etty was the first British artist to specialise in the nude, and the prurient reaction of the lower classes to these paintings caused concern throughout the 19th century. Although his portraits of male nudes were generally well received, many critics condemned his recurrent depictions of female nudity as indecent.
answer:

What is the full name of the person who became a student of a renowned portrait painter in July of 1807?
