TASK DEFINITION: In this task, you are given a set of context paragraphs, some supporting facts and an answer of a question. Your task is to generate question for given answer based on set of context paragraphs, supporting facts and an answer.
PROBLEM: Context_1 : The BDR Thermea Group is a European manufacturer of domestic and industrial heating appliances. The firm was created by the merger of Baxi and De Dietrich Remeha in 2009. Based in Apeldoorn, the Netherlands BDR Thermea provides heating and hot water products for UK, France, Germany, Spain, The Netherlands and Italy and has strong positions in the rapidly growing markets of Eastern Europe, Turkey, Russia, North America and China. In total BDR Thermea operates in more than 70 countries worldwide. Context_2 : The Warm Air Research House is a historic house and research facility located at 1108 W. Stoughton St. in Urbana, Illinois. Built in 1924, the house served as a warm-air heating research facility administered jointly by the National Warm-Air Heating and Ventilating Association and the University of Illinois Department of Mechanical Engineering. Prior to the 1920s, the American heating industry had few formal testing procedures for their products, and home heating through warm-air ventilation ducts was still considered a novel concept. The National Warm-Air Heating and Ventilating Association began to test heating methods and systems in the Department of Mechanical Engineering's laboratories, but it eventually needed a model house in which to test its domestic heating systems. The two organizations commissioned the large Colonial Revival residence, which was designed by architect Loring Harvey Provine and graduate student Clarence Andrew Kissinger. Beginning in 1932, research on air conditioning and cooling systems was also conducted in the house. Following World War II, the facility became less useful due to the shrinking size of new American homes, and the university sold the house in 1946. Some of the technologies developed in the house include storm windows, forced-air heating, and heating duct size and positioning. Context_3 : District heating (also known as heat networks or teleheating) is a system for distributing heat generated in a centralized location for residential and commercial heating requirements such as space heating and water heating. The heat is often obtained from a cogeneration plant burning fossil fuels but increasingly also biomass, although heat-only boiler stations, geothermal heating, heat pumps and central solar heating are also used, as well as nuclear power. District heating plants can provide higher efficiencies and better pollution control than localized boilers. According to some research, district heating with combined heat and power (CHPDH) is the cheapest method of cutting carbon emissions, and has one of the lowest carbon footprints of all fossil generation plants. A combination of CHP and centralized heat pumps are used in the Stockholm multi energy system. This allows the production of heat through electricity when there is an abundance of intermittent power production and cogeneration of electric power and district heating when the availability of intermittent power production is low. Context_4 : Pellet boilers are used as central heating systems for heat requirements (heating load) of more than 3.9kW (Kilowatt). But pellet central heating systems are not only used in single or two family homes (up to 30kW), but also for larger residential or business units with heat requirements of a few hundred kW. Pellet burner systems run most efficiently at full load and can usually be regulated down to up to 30% of its full capacity. Since the warm up phase of pellet ovens usually takes longer than for oil or gas firing systems, short burning phases have negative effects on the fuel efficiency. In order to improve energy efficiency and reduce harmful emissions, pellet ovens are usually combined with buffer systems like water tanks for example. Context_5 : De Dietrich Remeha is one of Europe's biggest manufacturers and distributors of domestic and commercial water and space heating systems. Headquartered in Apeldoorn in the Netherlands, it was founded in July 2004 after a merger between the Dutch firm Remeha, and the French firm De Dietrich Thermique. In July 2009, the heavily laden with debt British Baxi group agreed to merge with De Dietrich Remeha, creating the BDR Thermea Group. Context_6 : Baxi is a part of BDR Thermea, one of Europe's largest manufacturers and distributors of domestic and commercial water and space heating systems. Context_7 : Seasonal thermal energy storage (or STES) is the storage of heat or cold for periods of up to several months. The thermal energy can be collected whenever it is available and be used whenever needed, such as in the opposing season. For example, heat from solar collectors or waste heat from air conditioning equipment can be gathered in hot months for space heating use when needed, including during winter months. Waste heat from industrial process can similarly be stored and be used much later. Or the natural cold of winter air can be stored for summertime air conditioning. STES stores can serve district heating systems, as well as single buildings or complexes. Among seasonal storages used for heating, the design peak annual temperatures generally are in the range of 27 to , and the temperature difference occurring in the storage over the course of a year can be several tens of degrees. Some systems use a heat pump to help charge and discharge the storage during part or all of the cycle. For cooling applications, often only circulation pumps are used. A less common term for STES technologies is interseasonal thermal energy storage Context_8 : Rheem Manufacturing Company is an American privately held manufacturer that produces residential and commercial water heaters and boilers, as well as heating, ventilating and air conditioning (HVAC) equipment. The company also produces and sells products under the Ruud brand name. It is a subsidiary of Paloma Industries. What became Rheem started in 1925 as a supplier of packaging to the petroleum industry, and is currently headquartered in Atlanta, Georgia in the United States. The company is one of the largest manufacturers of both water heating and HVAC equipment in the United States, and also produces and markets products in Argentina, Armenia, Australia, Bahrain, Brazil, Canada, Iraq, Kuwait, Mexico, New Zealand, Oman, Qatar, Saudi Arabia, Singapore, UAE, and Ukraine. Context_9 : Historically, the main applications of solar energy technologies in Canada have been non-electric active solar system applications for space heating, water heating and drying crops and lumber. In 2001, there were more than 12,000 residential solar water heating systems and 300 commercial/ industrial solar hot water systems in use. These systems presently comprise a small fraction of Canada's energy use, but some government studies suggest they could make up as much as five per cent of the country's energy needs by the year 2025. Context_10 : Electric heating is a process in which electrical energy is converted to heat. Common applications include space heating, cooking, water heating and industrial processes. An electric heater is an electrical device that converts electric current to heat. The heating element inside every electric heater is an electrical resistor, and works on the principle of Joule heating: an electric current passing through a resistor will convert that electrical energy into heat energy. Most modern electric heating devices use nichrome wire as the active element; the heating element, depicted on the right, uses nichrome wire supported by ceramic insulators. fact_1 : In July 2009, the heavily laden with debt British Baxi group agreed to merge with De Dietrich Remeha, creating the BDR Thermea Group. fact_2 : Baxi is a part of BDR Thermea, one of Europe's largest manufacturers and distributors of domestic and commercial water and space heating systems. Answer: Baxi

SOLUTION: De Dietrich Remeha, is one of Europes biggest manufacturers and distributors of domestic and commercial water and space heating systems, in July 2009, when heavily laden with debt, which of Europes largest manufacturers and distributors of domestic and commercial water and space heating systems, agreed to merge with them?

PROBLEM: Context_1 : Principles of Philosophy (Latin: "Principia philosophiae" ) is a book by Rene Descartes. In essence it is a synthesis of the "Discourse on Method" and "Meditations on First Philosophy" It was written in Latin, published in 1644 and dedicated to Elisabeth of Bohemia, with whom Descartes had a long-standing friendship. A French version ("Les Principes de la Philosophie") followed in 1647. It set forth the principles of naturethe Laws of Physicsas Descartes viewed them. Most notably, it set forth the principle that in the absence of external forces, an object's motion will be uniform and in a straight line. Newton borrowed this principle from Descartes and included it in his own "Principia"; to this day, it is still generally referred to as Newton's First Law of Motion. The book was primarily intended to replace the Aristotelian curriculum then used in French and British Universities. The work provides a systematic statement of his metaphysics and natural philosophy, and represents the first truly comprehensive, mechanistic account of the universe. Context_2 : Maximilian de Gaynesford (born 1968) is an English philosopher and the author of "The Rift in the Lute: Attuning Poetry and Philosophy" (Oxford, 2017). He was educated at Ampleforth College and Balliol College, Oxford (19869; First in Modern History), after which he spent several years studying Theology, before turning to Philosophy in 1993. Before receiving his doctorate, he was elected Fellow and Tutor in Philosophy at Lincoln College, Oxford (1997). He was subsequently Humboldt Research Fellow at the Freie Universitat Berlin (2003) and a tenured professor at The College of William and Mary in Virginia (20022006) before becoming Professor of Philosophy (2008) and Head of Department (2016) at the University of Reading. He is the author of over forty articles and four books: "The Rift in the Lute: Attuning Poetry and Philosophy" (Oxford, 2017), "I: The Meaning of the First Person Term" (Oxford, 2006), "Hilary Putnam" (Routledge, 2006), and "John McDowell" (Polity, 2004). In 2011, he edited a collection of articles on the Philosophy of Action, "Agents And Their Actions" (Blackwell), which includes recent work by John McDowell and Joseph Raz. He often gives papers on attuning poetry and philosophy for general audiences, as here . He spoke at the Harvard Conference in celebration of Hilary Putnam, here . He has a daughter, Elisabeth (born 2009). Context_3 : Pragmaticism is a term used by Charles Sanders Peirce for his pragmatic philosophy starting in 1905, in order to distance himself and it from pragmatism, the original name, which had been used in a manner he did not approve of in the "literary journals". Peirce in 1905 announced his coinage "pragmaticism", saying that it was "ugly enough to be safe from kidnappers" ("Collected Papers" (CP) 5.414). Today, outside of philosophy, "pragmatism" is often taken to refer to a compromise of aims or principles, even a ruthless search for mercenary advantage. Peirce gave other or more specific reasons for the distinction in a surviving draft letter that year and in later writings. Peirce's pragmatism, that is, pragmaticism, differed in Peirce's view from other pragmatisms by its commitments to the spirit of strict logic, the immutability of truth, the reality of infinity, and the difference between (1) actively willing to control thought, to doubt, to weigh reasons, and (2) willing not to exert the will, willing to believe. In his view his pragmatism is, strictly speaking, not itself a whole philosophy, but instead a general method for the clarification of ideas. He first publicly formulated his pragmatism as an aspect of scientific logic along with principles of statistics and modes of inference in his "Illustrations of the Logic of Science" series of articles in 1877-8. Context_4 : Elisabeth of the Palatinate (26 December 1618 11 February 1680), also known as Elisabeth of Bohemia, Princess Elisabeth of the Palatinate, or Princess-Abbess of Herford Abbey, was the eldest daughter of Frederick V, Elector Palatine (who was briefly King of Bohemia), and Elizabeth Stuart. She was born in Heidelberg, Germany, spending the first nine years of her life there. When she was nine, she went to live in Leyden, with her brother and was raised in a nursery palace to complete her studies. After finishing her studies, she was deemed ready to live in The Hague with her mother. Context_5 : The Three Principles of the People, also translated as Three People's Principles, San-min Doctrine, or Tridemism is a political philosophy developed by Sun Yat-sen as part of a philosophy to make China a free, prosperous, and powerful nation. The three principles are often translated into and summarized as nationalism, democracy, and the livelihood of the people. He believed that the economic livelihood of the people depended on adopting the teachings of the American economist Henry George, writing that "The teachings of your single-taxer, Henry George, will be the basis of our program of reform." Context_6 : In computer programming, the term SOLID is a mnemonic acronym for five design principles intended to make software designs more understandable, flexible and maintainable. The principles are a subset of many principles promoted by Robert C. Martin, . Though they apply to any object-oriented design, the SOLID principles can also form a core philosophy for methodologies such as agile development or Adaptive Software Development. The SOLID acronym was introduced by Michael Feathers. Context_7 : Groundwork of the Metaphysics of Morals (German: "Grundlegung zur Metaphysik der Sitten" ; 1785; also known as the "Foundations of the Metaphysics of Morals", "Grounding of the Metaphysics of Morals" and the "Grounding for the Metaphysics of Morals") is the first of Immanuel Kant's mature works on moral philosophy and remains one of the most influential in the field. Kant conceives his investigation as a work of foundational ethicsone that clears the ground for future research by explaining the core concepts and principles of moral theory and showing that they are normative for rational agents. Kant aspires to nothing less than this: to lay bare the fundamental principle of morality and show that it applies to us. In the text, Kant provides a groundbreaking argument that the rightness of an action is determined by the character of the principle that a person chooses to act upon. Kant thus stands in stark contrast to the moral sense theories and teleological moral theories that dominated moral philosophy at the time he was writing. Central to the work is the role of what Kant refers to as the categorical imperative, the concept that one must act only according to that precept which he or she would will to become a universal law. Context_8 : In Canadian and New Zealand law, fundamental justice is the fairness underlying the administration of justice and its operation. The principles of fundamental justice are specific legal principles that command "significant societal consensus" as "fundamental to the way in which the legal system ought fairly to operate", per "R v Malmo-Levine". These principles may stipulate basic procedural rights afforded to anyone facing an adjudicative process or procedure that affects fundamental rights and freedoms, and certain substantive standards related to the rule of law that regulate the actions of the state (e.g., the rule against unclear or vague laws). The degree of protection dictated by these standards and procedural rights vary in accordance with the precise context, involving a contextual analysis of the affected person's interests. In other words, the more a person's rights or interests are adversely affected, the more procedural or substantive protections must be afforded to that person in order to respect the principles of fundamental justice. A legislative or administrative framework that respects the principles of fundamental justice, as such, must be fundamentally fair to the person affected, but does not necessarily have to strike the "right balance" between individual and societal interests in general. Context_9 : A first principle is a basic, foundational, self-evident proposition or assumption that cannot be deduced from any other proposition or assumption. In philosophy, first principles are taught by Aristotelians and a nuanced version of first principles are referred to as postulates by Kantians. In mathematics, first principles are referred to as axioms and postulates. In physics and other sciences, theoretical work is said to be from first principles, or "ab initio", if it starts directly at the level of established science and does not make assumptions such as empirical model and parameter fitting. Context_10 : Principia philosophiae cartesianae (PPC; "The Principles of Cartesian Philosophy") or Renati Descartes principia philosophiae, more geometrico demonstrata ("The Principles of Rene Descartes' Philosophy, Demonstrated in Geometrical Order") is a philosophical work of Baruch Spinoza published in Amsterdam in 1663. In the preface to this work, Ludovic Meyer explains that it is a reconstruction of Rene Descartes' "Principles of Philosophy "in the Euclidean or "geometric" fashion". "In the appendix, a series of non-geometric prose passages entitled "Metaphysical Thoughts" ["Cogitata Metaphisica"], Spinoza explicates Descartes' views on traditional metaphysical topics (including essence, existence, idea, potential, necessity, contingency, duration, and time) while furtively interpolating some of his own. fact_1 : In essence it is a synthesis of the "Discourse on Method" and "Meditations on First Philosophy" It was written in Latin, published in 1644 and dedicated to Elisabeth of Bohemia, with whom Descartes had a long-standing friendship. fact_2 : Elisabeth of the Palatinate (26 December 1618 11 February 1680), also known as Elisabeth of Bohemia, Princess Elisabeth of the Palatinate, or Princess-Abbess of Herford Abbey, was the eldest daughter of Frederick V, Elector Palatine (who was briefly King of Bohemia), and Elizabeth Stuart. Answer: Frederick V, Elector Palatine

SOLUTION: Who was the father of the person Principles of Philosophy was dedicated to?

PROBLEM: Context_1 : The conservation and restoration of vinyl discs refers to the preventive measures taken to defend against damage and slow degradation, and to maintain fidelity of singles, 12" singles, EP, LP in 45 or 33 rpm disc recordings. LPs are most often in the 12" format, although very early vinyl recordings were 10". Vinyl LP preservation is generally considered separate from conservation, which refers to the repair and stabilization of individual discs. Commonly practiced in major sound archives and research libraries that house large collections of audio recordings, it is also frequently followed by audiophiles and home record collectors. Because vinyla virtually unbreakable light plastic made up of polyvinyl chloride acetate copolymer, or PVCis considered the most stable of analog recording media, it is seen as less a concern for deterioration than earlier sound recordings made from more fragile materials such as acetate, vulcanite, or shellac. This hardly means that vinyl recordings are infallible, however, and researchboth expert and evidentialhas shown that the way in which discs are handled and cared for can have a profound effect on their longevity. Though some 45s (7"s) are also made from vinyl, many of them are actually polystyrenea more fragile medium that is prone to fracturing from internal stress. Still, many of the recommendations for the care of vinyl LPs can be applied to 45s. Context_2 : Vinyl acetate is an organic compound with the formula CHCOCHCH. A colorless liquid with a pungent odor, it is the precursor to polyvinyl acetate, an important polymer in industry. Unlike many other acetate esters, the odor of vinyl acetate is thoroughly disagreeable and is not used to any substantial degree as an odorant. Context_3 : Wacker Chemie AG is a worldwide operating company in the chemical business, founded 1914. The company is controlled by the Wacker family holding more than 50 percent of the shares. The corporation is operating more than 25 production sites in Europe, Asia, and the Americas. The product range includes silicone rubbers, polymer products like ethylene vinyl acetate redispersible polymer powder, chemical materials, polysilicon and wafers for semiconductor industry. The company sells its products in more than 100 countries. As of 31 December 2015, 16,972 employees have been with Wacker. Corporate annual sales in 2015 were about 5,3 billion Euros, up 10% compared to 2014. Context_4 : Polyketones are a family of high-performance thermoplastic polymers. The polar ketone groups in the polymer backbone of these materials gives rise to a strong attraction between polymer chains, which increases the material's melting point (255C for copolymer (carbon monoxide ethylene), 220C for terpolymer (carbon monoxide, ethylene, propylene). Trade names include Carilon, Karilon, Akrotek, and Schulaketon. Such materials also tend to resist solvents and have good mechanical properties. Unlike many other engineering plastics, aliphatic polyketones such as Shell Chemicals' Carilon are relatively easy to synthesize and can be derived from inexpensive monomers. Carilon is made with a palladium(II) catalyst from ethylene and carbon monoxide. A small fraction of the ethylene is generally replaced with propylene to reduce the melting point somewhat. Shell Chemical commercially launched Carilon thermoplastic polymer in the U.S.in 1996, but discontinued it in 2000. SRI International offers Carilon thermoplastic polymers. Hyosung announced that they would launch production in 2015 Context_5 : Ethylene-vinyl acetate (EVA), also known as poly (ethylene-vinyl acetate) (PEVA), is the copolymer of ethylene and vinyl acetate. The weight percent vinyl acetate usually varies from 10 to 40%, with the remainder being ethylene. Context_6 : Solutia Inc. is a global manufacturer of performance materials and specialty chemicals including polyvinyl butyral (PVB), ethylene vinyl acetate (EVA), and thermoplastic polyurethane (TPU) interlayers for laminated glass, aftermarket window films, protective barrier and conductive films, and rubber processing chemicals, used in architectural, automotive, alternative energy, electronic devices, consumer and industrial applications. The company was formed on September 1, 1997, as a divestiture of the Monsanto Company chemical business. In July 2012, the company was acquired by Eastman Chemical Company. Context_7 : EPDM rubber (ethylene propylene diene monomer (M-class) rubber), a type of synthetic rubber, is an elastomer characterized by a wide range of applications. The "M" refers to its classification in ASTM standard D-1418; the "M" class includes rubbers having a saturated chain of the polymethylene type. Dienes currently used in the manufacture of EPDM rubbers are dicyclopentadiene (DCPD), ethylidene norbornene (ENB), and vinyl norbornene (VNB). EPDM rubber is closely related to ethylene propylene rubber: ethylene propylene rubber is a copolymer of ethylene and propylene, whereas EPDM rubber is a terpolymer of ethylene, propylene, and a diene-component. Context_8 : Nanofibers are fibers with diameters in the nanometer range. Nanofibers can be generated from different polymers and hence have different physical properties and application potentials. Examples of natural polymers include collagen, cellulose, silk fibroin, keratin, gelatin and polysaccharides such as chitosan and alginate. Examples of synthetic polymers include poly(lactic acid) (PLA), polycaprolactone (PCL), polyurethane (PU), poly(lactic-co-glycolic acid) (PLGA), poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV), and poly(ethylene-co-vinylacetate) (PEVA). Polymer chains are connected via covalent bonds. The diameters of nanofibers depend on the type of polymer used and the method of production. All polymer nanofibers are unique for their large surface area-to-volume ratio, high porosity, appreciable mechanical strength, and flexibility in functionalization compared to their microfiber counterparts. Context_9 : Ethylene vinyl alcohol (EVOH) is a formal copolymer of ethylene and vinyl alcohol. Because the latter monomer mainly exists as its tautomer acetaldehyde, the copolymer is prepared by polymerization of ethylene and vinyl acetate to give the ethylene vinyl acetate (EVA) copolymer followed by hydrolysis. EVOH copolymer is defined by the mole % ethylene content: lower ethylene content grades have higher barrier properties; higher ethylene content grades have lower temperatures for extrusion. Context_10 : Polyvinyl chloride acetate (PVCA) is a thermoplastic copolymer of vinyl chloride and vinyl acetate. It is used in the manufacture of electrical insulation, of protective coverings (including garments), and of credit cards and swipe cards. fact_1 : Examples of synthetic polymers include poly(lactic acid) (PLA), polycaprolactone (PCL), polyurethane (PU), poly(lactic-co-glycolic acid) (PLGA), poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV), and poly(ethylene-co-vinylacetate) (PEVA). fact_2 : Ethylene-vinyl acetate (EVA), also known as poly (ethylene-vinyl acetate) (PEVA), is the copolymer of ethylene and vinyl acetate. Answer: Ethylene-vinyl acetate

SOLUTION:
What copolymer of ethylene and vinyl acetate can nanofibers be made of?
