Problem: The answer to the question: What is the last name of the person whose economics books they were reading at the time can be seen in the library? is inside the article: Manchester has a notable place in the history of Marxism and left-wing politics; being the subject of Friedrich Engels' work The Condition of the Working Class in England in 1844; Engels spent much of his life in and around Manchester, and when Karl Marx visited Manchester, they met at Chetham's Library. The economics books Marx was reading at the time can be seen in the library, as can the window seat where Marx and Engels would meet. The first Trades Union Congress was held in Manchester (at the Mechanics' Institute, David Street), from 2 to 6 June 1868. Manchester was an important cradle of the Labour Party and the Suffragette Movement.At that time, it seemed a place in which anything could happen—new industrial processes, new ways of thinking (the Manchester School, promoting free trade and laissez-faire), new classes or groups in society, new religious sects, and new forms of labour organisation. It attracted educated visitors from all parts of Britain and Europe. A saying capturing this sense of innovation survives today: "What Manchester does today, the rest of the world does tomorrow." Manchester's golden age was perhaps the last quarter of the 19th century. Many of the great public buildings (including Manchester Town Hall) date from then. The city's cosmopolitan atmosphere contributed to a vibrant culture, which included the Hallé Orchestra. In 1889, when county councils were created in England, the municipal borough became a county borough with even greater autonomy. Although the Industrial Revolution brought wealth to the city, it also brought poverty and squalor to a large part of the population. Historian Simon Schama noted that "Manchester was the very best and the very worst taken to terrifying extremes, a new kind of city in the world; the chimneys of industrial suburbs greeting you with columns of smoke". An American visitor taken to Manchester's blackspots saw "wretched, defrauded, oppressed, crushed human nature, lying and bleeding fragments".The number of cotton mills in Manchester itself..., can you guess it ?

Problem: The answer to the question: What are the first names of the people who invented the concept of "All?" is inside the article: The film begins with the Descendents' origins in the neighboring communities of Hermosa Beach and Manhattan Beach, California in the late 1970s. Middle school friends Frank Navetta and Dave Nolte start the band in 1977 by writing songs together on guitar. Classmate Bill Stevenson impresses them with his musical talents and becomes their drummer. In 1979 they meet bassist Tony Lombardo in Long Beach and recruit him to the band. Nolte bows out to join his brothers in The Last, and Navetta, Stevenson, and Lombardo record the Descendents' debut single. Stevenson's high school classmate Milo Aukerman joins the band as lead singer, and the new lineup builds a local following through their catchy and melodic songs, energetic live shows, and Aukerman's image as a nerd. They release the Fat EP (1981) and their debut album Milo Goes to College (1982), so named because Aukerman leaves the band to study biology. Stevenson drums in Black Flag for the next few years. In 1985 the Descendents reconvene for a second album, I Don't Want to Grow Up. Navetta has burned all of his equipment and moved to Oregon, and is replaced by Ray Cooper. Stevenson pushes for the band to tour, but Lombardo declines and quits. He is replaced by Doug Carrion, and this lineup records 1986's Enjoy!, after which Cooper and Carrion both leave the band. Stevenson recruits bassist Karl Alvarez from Salt Lake City, who brings in his close friend Stephen Egerton to play guitar. The new lineup releases the 1987 album All, themed around the philosophical concept of "All" invented by Stevenson and friend Pat McCuistion. Aukerman leaves the band again to attend graduate school., can you guess it ?

A: Bill


Problem: The answer to the question: What are the first names of the people who discover that their creation is aging at a vastly accelerated rate? is inside the article: Genetic engineers Clive Nicoli and Elsa Kast hope to achieve fame by splicing animal DNA to create hybrids for medical use at the company N.E.R.D. (Nucleic Exchange Research and Development). Their work previously yielded Fred, a dog-sized vermiform creature intended as a mate for their female specimen, Ginger. After successfully mating them, Clive and Elsa plan to create a human-animal hybrid that could revolutionize science. Their employers Joan Chorot of N.E.R.D. and William Barlow forbid them from doing this. Instead, they are to find and extract proteins used for commercial drug production from Fred and Ginger. Clive and Elsa, however, disobey their superiors and pursue their own agenda in secret, developing a viable prepubescent female creature. Although they had planned to terminate the hybrid before it reached full term, Elsa persuades Clive to let it live. They discover that she is aging at a vastly accelerated rate. Elsa discovers that the creature is undergoing mental development such as that of a young human child. Elsa names the creature "Dren" after the creature spells out NERD, having seen the letters on Elsa's shirt. After moving Dren to a new location for fear of discovery, they find she has a dangerously high fever. In an attempt to save her they place her in a large industrial sink filled with cold water. Later on Clive fully submerges Dren in the sink, and in doing so discovers that Dren is amphibious, but remains ambiguous in whether he tried to save Dren or kill her. While studying Dren, Elsa and Clive neglect their work with Fred and Ginger. At a highly publicized presentation of their work, Fred and Ginger savagely fight to the death. It is subsequently discovered that Ginger had spontaneously changed to a male, but Elsa and Clive failed to notice because they were focused on Dren., can you guess it ?
