Question:
A Night at the Opera is the fourth studio album by the British rock band Queen, released on 21 November 1975 by EMI Records in the United Kingdom and by Elektra Records in the United States. Produced by Roy Thomas Baker and Queen, it was the most expensive album ever recorded at the time of its release. The album takes its name from the Marx Brothers film of the same name, which the band watched one night at the studio complex when recording. A Night at the Opera incorporates a wide range of styles, including ballads, songs in a music hall style, hard rock tracks and progressive rock influences.
"Death on Two Legs" can be referred to as Freddie Mercury's hate letter to Queen's first manager, Norman Sheffield, who for some years was reputed to have mistreated the band and abused his role as their manager from 1972 to 1975. Sheffield denied the allegations in his 2013 autobiography entitled "Life on Two Legs: Set The Record Straight", and referred to copies of the original 1972 management contracts between Sheffield and Queen, which were included in the book as proof of his defence. Though the song never makes direct reference to him, after listening to a playback of the song at Trident Studios during the time of album release, Sheffield was appalled, and sued the band and the record label for defamation, which resulted in an out-of-court settlement, but also confirmed his connection to the song. During live performances, Mercury would usually rededicate the song to "a real motherfucker of a gentleman", although this line was censored on the version that appeared on their Live Killers album in 1979. Other than on the live album, he said it was dedicated to a "motherfucker I used to know". In the Classic Albums documentary about the making of A Night at the Opera, Brian May stated that the band was somewhat taken aback at first by the bitterness of Mercury's lyrics, and described by Mercury as being "so vindictive that he [May] felt bad singing it". After the song came together, it was agreed that the "author should have his way", and the song was recorded as written. As with "Bohemian Rhapsody", most of the guitar parts on this song were initially played on piano by Mercury, to demonstrate to May how they needed to be played on guitar. "Death on Two Legs" remained on the setlist until, and well into, The Game Tour in 1980, and was then dropped. However, the piano introduction was played during the Hot Space and Works tours.

input: Tu Youyou was born in Ningbo, Zhejiang, China on 30 December 1930. She attended Xiaoshi Middle School for junior high school and the first year of high school, before transferring to Ningbo Middle School in 1948. From 1951 to 1955, she attended Peking University Medical School / Beijing Medical College. Tu studied at the Department of Pharmaceutical Sciences, and graduated in 1955. Later Tu was trained for two and a half years in traditional Chinese medicine. After graduation, Tu worked at the Academy of Traditional Chinese Medicine (now the China Academy of Traditional Chinese Medical Sciences) in Beijing. She was promoted to a Researcher (Yan Jiu Yuan , the highest researcher rank in mainland China equivalent to the academic rank of a full professor) in 1980 shortly after the Chinese economic reform began in 1978. In 2001 she was promoted to academic advisor for doctoral candidates. Currently she is the Chief Scientist in the Academy. As of 2007, her office is in an old apartment building in Dongcheng District, Beijing. Before 2011, Tu Youyou had been obscure for decades, and is described as "almost completely forgotten by people". Tu is regarded as the Professor of Three Noes - no postgraduate degree (there was no postgraduate education then in China), no study or research experience abroad, and not a member of any Chinese national academies, i.e. Chinese Academy of Sciences and Chinese Academy of Engineering. Up until 1979, there were no postgraduate degree programs in China, and China was largely isolated from the rest of the world. Tu is now regarded as a representative figure of the first generation of Chinese medical workers since the establishment of the People's Republic of China in 1949.

Answer the question at the end by quoting:

Grandaddy is an American indie rock band from Modesto, California. The group was formed in 1992, and featured Jason Lytle, Aaron Burtch, Jim Fairchild, Kevin Garcia and Tim Dryden. After several self-released records and cassettes, the band signed to Will Records in the US and later the V2 subsidiary Big Cat Records in the UK, going on to sign an exclusive deal with V2. The bulk of the band's recorded output was the work of Lytle, who worked primarily in home studios.
Common lyrical themes include technology and a resistance to change. Adrien Begrand, writing for PopMatters, described the lyrics on The Sophtware Slump as "one's attempt to transcend the glut of technology in today's urban lifestyle, in search of something more real, more natural, more pastoral". Ben Sisario of The New York Times stated that the band "provided the soundtrack to dot-com-era alienation, singing in a cracked yet still innocent voice of life spent staring into a computer screen". Ross Raihala, reviewing Sumday for Spin, identified what he called Lytle's "geeky identification with technology". On The Sophtware Slump, CMJ writer Richard A. Martin commented on Lytle's "sympathy for the lost souls and machines of the high-tech dot-com landscape". Lytle described his empathy with machines in 2003, stating "I find it easier dealing with certain things by living through inanimate objects" and how the song "I'm on Standby" is about Lytle relating to a mobile phone: "I was spending so much time learning the art of turning off, while still being 'on'". Lytle said of the tracks on Excerpts from the Diary of Todd Zilla: "For some reason, they are tied together by the idea of being fed up with your environment." He stated in 2001: "I have a growing appreciation for that which is simple and natural. I get that from the outdoors, and seeing the accumulation of clutter and waste and not being too happy about it." There is also much humor in Lytle's songwriting, including the band's promotional Christmas single released in 2000, "Alan Parsons in a Winter Wonderland", which was also included on the charity compilation It's a Cool Cool Christmas, described by AllMusic's Tim DiGravina as possibly "the funniest song from 2000".
