Passage: When two grade-school boys get into a fight in the park that results in one boy, Zachary Cowan, hitting the other, Ethan Longstreet, in the face with a stick, their parents meet in a Brooklyn apartment to discuss the matter. Zachary's parents, Alan and Nancy Cowan, visit the home of Michael and Penelope Longstreet, Ethan's parents. Their meeting is initially intended to be short, but due to various circumstances, the conversation continues to draw out.
In fact, Alan and Nancy begin to leave the apartment on two occasions, but are drawn back in to further discussion.
At first, the couples are friendly to each other, but their respective comments start to hurt feelings, making everyone argue with one another. Apart from fighting among themselves, the couples blame each other about who is responsible for the fight between their sons. Nancy calls the Longstreets "superficially fair-minded" and Penelope and Michael complain about Alan's arrogant and dull attitude. Everyone also gets irritated with Alan when he accepts endless business phone calls on his BlackBerry, interrupting the discussion, and showing he has more interest in his business problems than the matter at hand. Michael also receives many phone calls from his ailing mother, to his frustration.
Nancy accuses Michael of being a murderer because he, annoyed by the constant noise it made during the night, had earlier turned his daughter Courtney's pet hamster loose in the street. Penelope becomes emotional about the hamster and with everyone arguing with each other. Other issues include a risky drug Alan is working to defend and Michael's mother has been prescribed, and the question of idealism and responsibility that is part of Penelope's current work. 
Question: Who is Courtney's father?
answer:
Michael.

Passage: Radiohead are  an English rock band formed in Abingdon-on-Thames in 1985. The band consists of Thom Yorke (vocals, guitar, piano, keyboards), brothers Jonny Greenwood (lead guitar, keyboards, other instruments) and Colin Greenwood (bass), Ed O'Brien (guitar, backing vocals) and Philip Selway (drums, percussion). They have worked with producer Nigel Godrich and cover artist Stanley Donwood since 1994.
After signing to EMI in 1991, Radiohead released their debut single "Creep" in 1992. It became a worldwide hit after the release of their debut album, Pablo Honey (1993). Their popularity and critical standing rose in the United Kingdom with the release of their second album, The Bends (1995). Radiohead's third album, OK Computer (1997), brought them international fame; noted for its complex production and themes of modern alienation, it is often acclaimed as a landmark record of the 1990s and one of the best albums in popular music. Kid A (2000) and Amnesiac (2001), recorded simultaneously, marked a dramatic change in style, incorporating influences from experimental electronic music, 20th-century classical music, krautrock, and jazz. Kid A divided listeners but was named the best album of the decade by Rolling Stone, Pitchfork and The Times.
Hail to the Thief (2003) mixed rock and electronic music with lyrics inspired by the War on Terror, and was Radiohead's final album for EMI. Their subsequent releases have pioneered alternative release platforms such as pay-what-you-want and BitTorrent; Radiohead self-released their seventh album, In Rainbows (2007), as a download for which customers could set their own price, to critical and chart success. Their eighth album, The King of Limbs (2011), an exploration of rhythm, was developed using extensive looping and sampling. A Moon Shaped Pool (2016) prominently featured Jonny Greenwood's orchestral arrangements.
Radiohead had sold more than 30 million albums worldwide by 2011. Their work places highly in both listener polls and critics' lists of the best music of the 1990s and 2000s. In 2005, they were ranked 73rd in Rolling Stone's list of "The Greatest Artists of All Time"; Jonny Greenwood and O'Brien were included in Rolling Stone's list of greatest guitarists, and Yorke in their list of greatest singers. In 2009, Rolling Stone readers voted Radiohead the second-best artist of the 2000s. They were inducted into the Rock and Roll Hall of Fame in 2019. 
Question: Who has worked with Nigel Godrich since 1994?
answer:

Radiohead.
