Passage: Yorke said that the starting point for the record was the "incredibly dense and terrifying sound" of Bitches Brew, the 1970 avant-garde jazz fusion album by Miles Davis. He described the sound of Bitches Brew to Q: "It was building something up and watching it fall apart, that's the beauty of it. It was at the core of what we were trying to do with OK Computer." Yorke identified "I'll Wear It Proudly" by Elvis Costello, "Fall on Me" by R.E.M., "Dress" by PJ Harvey and "A Day in the Life" by the Beatles as particularly influential on his songwriting. Radiohead drew further inspiration from the recording style of film soundtrack composer Ennio Morricone and the krautrock band Can, musicians Yorke described as "abusing the recording process". Jonny Greenwood described OK Computer as a product of being "in love with all these brilliant records ... trying to recreate them, and missing."According to Yorke, Radiohead hoped to achieve an "atmosphere that's perhaps a bit shocking when you first hear it, but only as shocking as the atmosphere on the Beach Boys' Pet Sounds." They expanded their instrumentation to include electric piano, Mellotron, cello and other strings, glockenspiel and electronic effects. Jonny Greenwood summarised the exploratory approach as "when we've got what we suspect to be an amazing song, but nobody knows what they're gonna play on it." Spin characterised OK Computer as sounding like "a DIY electronica album made with guitars".Critics suggested a stylistic debt to 1970s progressive rock, an influence that Radiohead have disavowed. According to Andy Greene in Rolling Stone, Radiohead "were collectively hostile to seventies progressive rock ... but that didn't stop them from reinventing prog from scratch on OK Computer, particularly on the six-and-a-half-minute 'Paranoid Android'." Writing in 2017, The New Yorker's Kelefa Sanneh said OK Computer "was profoundly prog: grand and dystopian, with a lead single that was more than six minutes long.". 
Question: What is the name of the person who described the sound of Bitches Brew as "building something up and watching it fall apart"?
Yorke.

Passage: Caspar David Friedrich was born on 5 September 1774, in Greifswald, Swedish Pomerania, on the Baltic coast of Germany. The sixth of ten children, he was brought up in the strict Lutheran creed of his father Adolf Gottlieb Friedrich, a candle-maker and soap boiler. Records of the family's financial circumstances are contradictory; while some sources indicate the children were privately tutored, others record that they were raised in relative poverty. Caspar David was familiar with death from an early age. His mother, Sophie Dorothea Bechly, died in 1781 when he was just seven. A year later, his sister Elisabeth died, while a second sister, Maria, succumbed to typhus in 1791. Arguably the greatest tragedy of his childhood happened in 1787 when his brother Johann Christoffer died: at the age of thirteen, Caspar David witnessed his younger brother fall through the ice of a frozen lake, and drown. Some accounts suggest that Johann Christoffer perished while trying to rescue Caspar David, who was also in danger on the ice.
Friedrich began his formal study of art in 1790 as a private student of artist Johann Gottfried Quistorp at the University of Greifswald in his home city, at which the art department is now named Caspar-David-Friedrich-Institut in his honour. Quistorp took his students on outdoor drawing excursions; as a result, Friedrich was encouraged to sketch from life at an early age. Through Quistorp, Friedrich met and was subsequently influenced by the theologian Ludwig Gotthard Kosegarten, who taught that nature was a revelation of God. Quistorp introduced Friedrich to the work of the German 17th-century artist Adam Elsheimer, whose works often included religious subjects dominated by landscape, and nocturnal subjects. During this period he also studied literature and aesthetics with Swedish professor Thomas Thorild. Four years later Friedrich entered the prestigious Academy of Copenhagen, where he began his education by making copies of casts from antique sculptures before proceeding to drawing from life. Living in Copenhagen afforded the young painter access to the Royal Picture Gallery's collection of 17th-century Dutch landscape painting. At the Academy he studied under teachers such as Christian August Lorentzen and the landscape painter Jens Juel. These artists were inspired by the Sturm und Drang movement and represented a midpoint between the dramatic intensity and expressive manner of the budding Romantic aesthetic and the waning neo-classical ideal. Mood was paramount, and influence was drawn from such sources as the Icelandic legend of Edda, the poems of Ossian and Norse mythology. 
Question: What is the full name of the man who taught taught that nature was a revelation of God to the person who lost his mother when he was seven?
Ludwig Gotthard Kosegarten.

Passage: According to academic Rob Wilson, San Francisco is a global city, a status that pre-dated the city's popularity during the California Gold Rush. Such cities are characterized by their ethnic clustering, network of international connectivity, and convergence of technological innovation. Global cities, such as San Francisco, are considered to be complex and require a high level of talent as well as large masses of low wage workers. A divide is created within the city of ethnic, typically lower-class neighborhoods, and expensive ones with newly developed buildings. This in turn creates a population of highly educated, white-collar individuals as well as blue-collar workers, many of whom are immigrants, and who both are drawn to the increasing number of opportunities available. Competition for these opportunities pushes growth and adaptation in world centers.San Francisco has a diversified service economy, with employment spread across a wide range of professional services, including financial services, tourism, and (increasingly) high technology. In 2016, approximately 27% of workers were employed in professional business services; 14% in leisure and hospitality; 13% in government services; 12% in education and health care; 11% in trade, transportation, and utilities; and 8% in financial activities. In 2017, GDP in the five-county San Francisco metropolitan area grew 3.4% to $501 billion. Additionally, in 2017 the 14-county San Jose–San Francisco–Oakland combined statistical area had a GDP of $907 billion, ranking 3rd among CSAs, and ahead of all but 16 countries. As of 2017, San Francisco County was the 7th highest-income county in the United States (among 3,142), with a per capita personal income of $119,868. Marin County, directly to the north over the Golden Gate Bridge, and San Mateo County, directly to the south on the Peninsula, were the 5th and 9th highest-income counties respectively. 
Question: What county has the 9th highest-income county in the United States?

San Mateo County.
