user: Problem: 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: Robert Owen (; 14 May 1771 - 17 November 1858) was a Welsh textile manufacturer, philanthropic social reformer, and one of the founders of utopian socialism and the cooperative movement. Owen is best known for his efforts to improve the working conditions of his factory workers and his promotion of experimental socialistic communities.
Context: In July 1799 Owen and his partners bought the New Lanark mill from David Dale, and Owen became the New Lanark mill's manager in January 1800. Encouraged by his success in the management of cotton mills in Manchester, Owen hoped to conduct the New Lanark mill on higher principles than purely commercial ones. David Dale and Richard Arkwright had established the substantial mill at New Lanark in 1785. With its water power provided by the falls of the River Clyde, the cotton-spinning operation became one of Britain's largest. About 2,000 individuals were associations with the mill; 500 of them were children who were brought to the mill at the age of five or six from the poorhouses and charities of Edinburgh and Glasgow. Dale, who was known for his benevolence, treated the children well, but the general condition of New Lanark's residents was unsatisfactory. Over the years, Dale and his son-in-law, Owen, worked to improve the factory workers' lives.  Many of the workers were in the lowest levels of the population; theft, drunkenness, and other vices were common; education and sanitation were neglected; and most families lived in one room. The respectable country people refused to submit to the long hours and demoralising drudgery of the mills.  Until a series of Truck Acts (1831-1887) required employees to be paid in common currency, many employers operated the truck system that paid workers in total or in part with tokens. The tokens had no monetary value outside the mill owner's "truck shop," where the owners could supply shoddy goods and charge top prices. In contrast to other employers, Owen's store offered goods at prices slightly above their wholesale cost. He also passed on the savings from the bulk purchase of goods to his workers, and placed the sale of alcohol under strict supervision. These principles became the basis for the cooperative shops in Britain, which continue in an altered form to trade today.
