user: Found the following article online, use it to answer the question: What is the last name of Sarah's old teacher?  College student Sarah Foster is found by the police, as she is sleepwalking in her nightgown on the road. Since the suicide of her husband Jonathon, who worked as a novelist, she is suffering from sleep disorder. A few days later, she talks to Dr Cooper, whose student she was, about the sleepwalking and a recurring nightmare, in which she is attacked by an unknown man. Cooper sends her to a therapy in a sleep laboratory. During a walk on a cemetery, Sarah talks about it with her room mate Dawn, who shows a personal interest in her professor Owen. Then an attractive man gets out of a black car and Sarah imagines him being a single. At the evening in the sleep laboratory, Dr. Koslov explains to her that her neuronal activity will be observed during the night. He also introduces her to Dr. Scott White, the director of the lab. It is the man whom Sarah has seen at the cemetery. He tells her, that a student was buried and he was there with a colleague. Sarah confides to him that she loved her husband, but not his work as a novelist. The next morning she wakes up in a different room after a silent, dreamless night. White takes her case. He reports about irregularities in the theta waves and asks her to spend some more nights in the lab. Sarah recognizes that something is wrong. In the lecture hall she questions the statement of her teacher, who thinks that love stories are just a dopamine kick or a bipolar disorder. But she is even more irritated when he addresses her as Miss Wells and a student repeats this name. Also Dawn, her driver's license, her diary and a dedication in her husband's book affirm this surname. Sarah is rejected by Cooper's assistant. In the sleep laboratory Dr Koslov shows her a protocol about her dream in which she is pursued. She denies having dreamed anything, but sees her signature on the form.

Q: Found the following article online, use it to answer the question: What was the last name of the person who used a powerful amplifier in Foo Fighters songs?  Grunge is generally characterized by a sludgy electric guitar sound with a "thick" middle register and rolled-off treble tone and a high level of distortion and fuzz, typically created with small 1970s-style stompbox pedals, with some guitarists chaining several fuzz pedals together and plugging them into a tube amplifier and speaker cabinet. Grunge guitarists use very loud Marshall guitar amplifiers  and some used powerful Mesa-Boogie amplifiers, including Kurt Cobain and Dave Grohl (the latter in early, grunge-oriented Foo Fighters songs ). Grunge has been called the rock genre with the most "lugubrious sound"; the use of heavy distortion and loud amps has been compared to a massive "buildup of sonic fog". or even dismissed as "noise" by one critic. As with metal and punk, a key part of grunge's sound is very distorted power chords played on the electric guitar.Whereas metal guitarists' overdriven sound generally comes from a combination of overdriven amplifiers and distortion pedals, grunge guitarists typically got all of their "dirty" sound from overdrive and fuzz pedals, with the amp just used to make the sound louder. Grunge guitarists tended to use the Fender Twin Reverb and the Fender Champion 100 combo amps (Cobain used both of these amps). The use of pedals by grunge guitarists was a move away from the expensive, studio-grade rackmount effects units used in other rock genres. The positive way that grunge bands viewed stompbox pedals can be seen in Mudhoney's use of the name of two overdrive pedals, the Univox Super-Fuzz and the Big Muff, in the title of their "debut EP Superfuzz Bigmuff".  In the song Mudride, the band's guitars were said to have "growled malevolently" through its "Cro-magnon slog".
A: Grohl
Found the following article online, use it to answer the question: What is the last name of the person who suggested the theme of Ulysses encountering the Sirens?  York-born William Etty (1787–1849) had originally been an apprentice printer in Hull, but on completing his apprenticeship at the age of 18 moved to London to become an artist. Strongly influenced by the works of Titian and Rubens, he became famous for painting nude figures in biblical, literary and mythological settings. While many of his peers greatly admired him and elected him a full Royal Academician in 1828, others condemned the content of his work as indecent.Throughout his early career Etty was highly regarded by wealthy lawyer Thomas Myers, who had been educated at Eton College and thus had a good knowledge of classical mythology. From 1832 onwards Myers regularly wrote to Etty to suggest potential subjects for paintings. Myers was convinced that there was a significant market for very large paintings, and encouraged Etty to make such works. In 1834, he suggested the theme of Ulysses ("Odysseus" in the original Greek) encountering the Sirens, a scene from the Odyssey in which a ship's crew sails past the island home of the Sirens. The Sirens were famous for the beauty of their singing, which would lure sailors to their deaths. Ulysses wanted to hear their song, so had his crew lash him to the ship's mast under strict orders not to untie him, after which they blocked their ears until they were safely out of range of the island.The topic of Ulysses encountering the Sirens was well suited to Etty's taste; as he wrote at the time, "My aim in all my great pictures has been to paint some great moral on the heart ... the importance of resisting SENSUAL DELIGHTS". In his depiction of the scene, he probably worked from Alexander Pope's translation, "Their song is death, and makes destruction please. / Unblest the man whom music wins to stay / Nigh the curs'd shore, and listen to the lay ... In verdant meads they sport, and wide around / Lie human bones that whiten all the ground. / The ground polluted floats with human gore / And human carnage taints the dreadful shore."
