Input: Read this: General Electric heavily contaminated the Hudson River with polychlorinated biphenyls (PCBs) between 1947-77. This pollution caused a range of harmful effects to wildlife and people who eat fish from the river or drink the water. In response to this contamination, activists protested in various ways. Musician Pete Seeger founded the Hudson River Sloop Clearwater and the Clearwater Festival to draw attention to the problem. The activism led to the site being designated by the EPA as one of the superfund sites requiring extensive cleanup. Other sources of pollution, including mercury contamination and sewage dumping, have also contributed to problems in the Hudson River watershed.
Question: Who founded the Hudson River Sloop Clearwater and the Clearwater Festival to bring attention to the pollution caused by GE?

Output: Pete Seeger

QUES: The Mature Indus civilisation flourished from about 2600 to 1900 BCE, marking the beginning of urban civilisation on the subcontinent. The civilisation included urban centres such as Dholavira, Kalibangan, Ropar, Rakhigarhi, and Lothal in modern-day India, as well as Harappa, Ganeriwala, and Mohenjo-daro in modern-day Pakistan. The civilisation is noted for its cities built of brick, roadside drainage system, and multistoreyed houses and is thought to have had some kind of municipal organization.

What kind of organization did the Mature Indus have?
What is the answer?
ANS: municipal

QUES: The first blue-violet LED using magnesium-doped gallium nitride was made at Stanford University in 1972 by Herb Maruska and Wally Rhines, doctoral students in materials science and engineering. At the time Maruska was on leave from RCA Laboratories, where he collaborated with Jacques Pankove on related work. In 1971, the year after Maruska left for Stanford, his RCA colleagues Pankove and Ed Miller demonstrated the first blue electroluminescence from zinc-doped gallium nitride, though the subsequent device Pankove and Miller built, the first actual gallium nitride light-emitting diode, emitted green light. In 1974 the U.S. Patent Office awarded Maruska, Rhines and Stanford professor David Stevenson a patent for their work in 1972 (U.S. Patent US3819974 A) and today magnesium-doping of gallium nitride continues to be the basis for all commercial blue LEDs and laser diodes. These devices built in the early 1970s had too little light output to be of practical use and research into gallium nitride devices slowed. In August 1989, Cree introduced the first commercially available blue LED based on the indirect bandgap semiconductor, silicon carbide (SiC). SiC LEDs had very low efficiency, no more than about 0.03%, but did emit in the blue portion of the visible light spectrum.[citation needed]
What students developed the first blue-violet LED?

ANS: Herb Maruska and Wally Rhines

Early recommendations for the quantity of water required for maintenance of good health suggested that 68 glasses of water daily is the minimum to maintain proper hydration. However the notion that a person should consume eight glasses of water per day cannot be traced to a credible scientific source. The original water intake recommendation in 1945 by the Food and Nutrition Board of the National Research Council read: "An ordinary standard for diverse persons is 1 milliliter for each calorie of food. Most of this quantity is contained in prepared foods." More recent comparisons of well-known recommendations on fluid intake have revealed large discrepancies in the volumes of water we need to consume for good health. Therefore, to help standardize guidelines, recommendations for water consumption are included in two recent European Food Safety Authority (EFSA) documents (2010): (i) Food-based dietary guidelines and (ii) Dietary reference values for water or adequate daily intakes (ADI). These specifications were provided by calculating adequate intakes from measured intakes in populations of individuals with "desirable osmolarity values of urine and desirable water volumes per energy unit consumed." For healthful hydration, the current EFSA guidelines recommend total water intakes of 2.0 L/day for adult females and 2.5 L/day for adult males. These reference values include water from drinking water, other beverages, and from food. About 80% of our daily water requirement comes from the beverages we drink, with the remaining 20% coming from food. Water content varies depending on the type of food consumed, with fruit and vegetables containing more than cereals, for example. These values are estimated using country-specific food balance sheets published by the Food and Agriculture Organisation of the United Nations. Other guidelines for nutrition also have implications for the beverages we consume for healthy hydration- for example, the World Health Organization (WHO) recommend that added sugars should represent no more than 10% of total energy intake.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What was the early recommended amount of water that was supposedly required to keep the body hydrated?
Ah, so.. 68 glasses of water daily

Question: Almost all of the composers who are described in music textbooks on classical music and whose works are widely performed as part of the standard concert repertoire are male composers, even though there has been a large number of women composers throughout the classical music period. Musicologist Marcia Citron has asked "[w]hy is music composed by women so marginal to the standard 'classical' repertoire?" Citron "examines the practices and attitudes that have led to the exclusion of women composers from the received 'canon' of performed musical works." She argues that in the 1800s, women composers typically wrote art songs for performance in small recitals rather than symphonies intended for performance with an orchestra in a large hall, with the latter works being seen as the most important genre for composers; since women composers did not write many symphonies, they were deemed to be not notable as composers. In the "...Concise Oxford History of Music, Clara Shumann [sic] is one of the only [sic] female composers mentioned." Abbey Philips states that "[d]uring the 20th century the women who were composing/playing gained far less attention than their male counterparts."
Try to answer this question if possible: Who is one of the only female composers mentioned?
Answer: Clara Shumann

Input: Read this: The Great Garden is an important European baroque garden. The palace itself, however, was largely destroyed by Allied bombing but is currently under reconstruction.[citation needed] Some points of interest are the Grotto (the interior was designed by the French artist Niki de Saint-Phalle), the Gallery Building, the Orangerie and the two pavilions by Remy de la Fosse. The Great Garden consists of several parts. The most popular ones are the Great Ground and the Nouveau Jardin. At the centre of the Nouveau Jardin is Europe's highest garden fountain. The historic Garden Theatre inter alia hosted the musicals of the German rock musician Heinz Rudolf Kunze.[citation needed]
Question: What are the two least popular areas of the garden?
