Background: Tu Youyou (Chinese: Tu You You ; pinyin: Tu Youyou; born 30 December 1930) is a Chinese pharmaceutical chemist and educator. She is best known for discovering artemisinin (also known as qinghaosu) and dihydroartemisinin, used to treat malaria, which has saved millions of lives.
Context: Tu Youyou carried on her work in the 1960s and 70s during China's Cultural Revolution, when scientists were denigrated as one of the nine black categories in society according to Maoist theory (or possibly that of the Gang of Four). In 1967, during the Vietnam War, Ho Chi Minh, the leader of North Vietnam, which was at war against South Vietnam and the United States, asked Chinese Premier Zhou Enlai for help in developing a malaria treatment for his soldiers trooping down the Ho Chi Minh trail, where a majority came down with a form of malaria which is resistant to chloroquine. Because malaria was also a major cause of death in China's southern provinces including Hainan, Yunnan, Guangxi, and Guangdong, Zhou Enlai convinced Mao Zedong to set up a secret drug discovery project, named Project 523 after its starting date, 23 May 1967. Upon joining the project unit, Tu was initially sent to Hainan where she studied patients who had been infected with the disease. During the time she spent there, her husband was banished to the countryside, meaning that her daughter had to be entrusted to a nursery in Beijing. Scientists worldwide had screened over 240,000 compounds without success. In 1969, Tu Youyou, then 39 years old, had an idea of screening Chinese herbs. She first investigated the Chinese medical classics in history, visiting practitioners of traditional Chinese medicine all over the country on her own. She gathered her findings in a notebook called A Collection of Single Practical Prescriptions for Anti-Malaria. Her notebook summarized 640 prescriptions. Her team also screened over 2,000 traditional Chinese recipes and made 380 herbal extracts, which were tested on mice. One compound was effective, sweet wormwood (Artemisia annua), which was used for "intermittent fevers," a hallmark of malaria. As Tu also presented at the project seminar, its preparation was described in a 1,600-year-old text, in a recipe titled, "Emergency Prescriptions Kept Up One's Sleeve". At first, it didn't work, because they extracted it with traditional boiling water. Tu Youyou discovered that a low-temperature extraction process could be used to isolate an effective antimalarial substance from the plant; Tu says she was influenced by a traditional Chinese herbal medicine source, The Handbook of Prescriptions for Emergency Treatments, written in 340 by Ge Hong, which states that this herb should be steeped in cold water. This book contained the useful reference to the herb: "A handful of qinghao immersed with two litres of water, wring out the juice and drink it all." After rereading the recipe, Tu realised the hot water had already damaged the active ingredient in the plant; therefore she proposed a method using low-temperature ether to extract the effective compound instead. The animal tests showed it was completely effective in mice and monkeys. Furthermore, Tu volunteered to be the first human subject. "As head of this research group, I had the responsibility" she said. It was safe, so she conducted successful clinical trials with human patients. Her work was published anonymously in 1977. In 1981, she presented the findings relating to artemisinin at a meeting with the World Health Organization.
Question: What did she test on?
Answer: The animal tests showed it was completely effective in mice and monkeys.

Problem: Background: Andy Warhol (; born Andrew Warhola; August 6, 1928 - February 22, 1987) was an American artist, director and producer who was a leading figure in the visual art movement known as pop art. His works explore the relationship between artistic expression, celebrity culture, and advertising that flourished by the 1960s, and span a variety of media, including painting, silkscreening, photography, film, and sculpture. Some of his best known works include the silkscreen paintings Campbell's Soup Cans (1962) and Marilyn Diptych (1962), the experimental film Chelsea Girls (1966), and the multimedia events known as the Exploding Plastic Inevitable (1966-67). Born and raised in Pittsburgh, Warhol initially pursued a successful career as a commercial illustrator.
Context: In the mid-1960s, Warhol adopted the band the Velvet Underground, making them a crucial element of the Exploding Plastic Inevitable multimedia performance art show. Warhol, with Paul Morrissey, acted as the band's manager, introducing them to Nico (who would perform with the band at Warhol's request). In 1966 he "produced" their first album The Velvet Underground & Nico, as well as providing its album art. His actual participation in the album's production amounted to simply paying for the studio time. After the band's first album, Warhol and band leader Lou Reed started to disagree more about the direction the band should take, and their artistic friendship ended. In 1989, after Warhol's death, Reed and John Cale re-united for the first time since 1972 to write, perform, record and release the concept album Songs for Drella, a tribute to Warhol. Warhol designed many album covers for various artists starting with the photographic cover of John Wallowitch's debut album, This Is John Wallowitch!!! (1964). He designed the cover art for The Rolling Stones' albums Sticky Fingers (1971) and Love You Live (1977), and the John Cale albums The Academy in Peril (1972) and Honi Soit in 1981. One of Warhol's last works was a portrait of Aretha Franklin for the cover of her 1986 gold album Aretha, which was done in the style of the Reigning Queens series he had completed the year before. Warhol strongly influenced the new wave/punk rock band Devo, as well as David Bowie. Bowie recorded a song called "Andy Warhol" for his 1971 album Hunky Dory. Lou Reed wrote the song "Andy's Chest", about Valerie Solanas, the woman who shot Warhol, in 1968. He recorded it with the Velvet Underground, and this version was released on the VU album in 1985. Bowie would later play Warhol in the 1996 movie, Basquiat. Bowie recalled how meeting Warhol in real life helped him in the role, and recounted his early meetings with him: I met him a couple of times, but we seldom shared more than platitudes. The first time we saw each other an awkward silence fell till he remarked my bright yellow shoes and started talking enthusiastically. He wanted to be very superficial. And seemingly emotionless, indifferent, just like a dead fish. Lou Reed described him most profoundly when he once told me they should bring a doll of Andy on the market: a doll that you wind up and doesn't do anything. But I managed to observe him well, and that was a helping hand for the film [Basquiat]. ... We borrowed his clothes from the museum in Pittsburgh, and they were intact, unwashed. Even the pockets weren't emptied: they contained pancake, white, deadly pale fond de teint which Andy always smeared on his face, a check torn in pieces, someone's address, lots of homeopathic pills and a wig. Andy always wore those silver wigs, but he never admitted it were wigs. One of his hairdressers has told me lately that he had his wigs regularly cut, like it were real hair. When the wig was trimmed, he put on another next month as if his hair had grown.
Question: Did Andy Warhol express his support for any musical artists?
Answer:
Lou Reed wrote the song "Andy's Chest", about Valerie Solanas, the woman who shot Warhol,
