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?

Ex Output:
Ludwig Gotthard Kosegarten.

Passage: The Kinks are regarded as one of the most influential rock acts of the 1960s and early 1970s. Stephen Thomas Erlewine called The Kinks "one of the most influential bands of the British Invasion". They were ranked 65th on Rolling Stone Magazine's "100 Greatest Artists of All Time" list.Artists influenced by The Kinks include punk rock groups such as the Ramones, The Clash, and The Jam, heavy metal acts including Van Halen and Britpop groups such as Oasis, Blur and Pulp. Craig Nicholls, singer and guitarist of The Vines, described the Kinks as "great songwriters, so underrated". Pete Townshend, guitarist with the Kinks' contemporaries the Who, credited Ray Davies with inventing "a new kind of poetry and a new kind of language for pop writing that influenced me from the very, very, very beginning." Jon Savage wrote that The Kinks were an influence on late 1960s American psychedelic rock groups "like The Doors, Love and Jefferson Airplane". Music writers and other musicians have acknowledged the influence of the Kinks on the development of hard rock and heavy metal. Musicologist Joe Harrington stated: "'You Really Got Me', 'All Day and All of the Night' and 'I Need You' were predecessors of the whole three-chord genre... [T]he Kinks did a lot to help turn rock 'n' roll (Jerry Lee Lewis) into rock." Queen guitarist Brian May credited the band with planting "the seed which grew into riff-based music."A musical, Sunny Afternoon, based on the early life of Ray Davies and the formation of the Kinks, opened at the Hampstead Theatre in April 2014. The musical's name came from the band's 1966 hit single "Sunny Afternoon" and features songs from the band's back catalogue.In 2015, it was reported that Julien Temple would direct a biopic of The Kinks titled You Really Got Me, with singer-songwriter Johnny Flynn and actor George MacKay cast to play Ray and Dave Davies, respectively. 
Question: What are the names of the four songs that were recorded by the Kinks that are mentioned in the passage?

Ex Output:
You Really Got Me.

Passage: In 2016, the United States is in a sustained economic depression. Industrial disasters, resource shortages, and gasoline prices at $37 per gallon have made railroads the primary mode of transportation, but even they are in disrepair. After a major accident on the Rio Norte line of the Taggart Transcontinental railroad, CEO James Taggart shirks responsibility. His sister Dagny Taggart, Vice-President in Charge of Operations, defies him by replacing the aging track with new rails made of Rearden Metal, which is claimed to be lighter yet stronger than steel. Dagny meets with its inventor, Hank Rearden, and they negotiate a deal they both admit serves their respective self-interests.
Politician Wesley Mouch—nominally Rearden's lobbyist in Washington, D.C.—is part of a crowd that views heads of industry as persons who must be broken or tamed. James Taggart uses political influence to ensure that Taggart Transcontinental is designated the exclusive railroad for the state of Colorado. Dagny is confronted by Ellis Wyatt, a Colorado oil man angry to be forced to do business with Taggart Transcontinental. Dagny promises him that he will get the service he needs. Dagny encounters former lover Francisco d'Anconia, who presents a façade of a playboy grown bored with the pursuit of money. He reveals that a series of copper mines he built are worthless, costing his investors (including the Taggart railroad) millions.
Rearden lives in a magnificent home with a wife and a brother who are happy to live off his effort, though they overtly disrespect it. Rearden's anniversary gift to his wife Lillian is a bracelet made from the first batch of Rearden Metal, but she considers it a garish symbol of Hank's egotism. At a dinner party, Dagny dares Lillian to exchange it for Dagny's diamond necklace, which she does. 
Question: What is the full name of the person who reveals that a series of copper mines they built are worthless?

Ex Output:

Francisco d'Anconia.
