Information: - Yale University is an American private Ivy League research university in New Haven, Connecticut. Founded in 1701 in Saybrook Colony to train Congregationalist ministers, it is the third-oldest institution of higher education in the United States. - Arthur Melvin '' Art '' Okun ( November 28 , 1928 -- March 23 , 1980 ) was an American economist . He served as the chairman of the Council of Economic Advisers between 1968 and 1969 . Before serving on the C.E.A. , he was a professor at Yale University , and afterwards was a fellow at the Brookings Institution in Washington , D.C. Okun is known in particular for promulgating Okun 's law , an observed relationship that states that for every 1 % increase in the unemployment rate , a country 's GDP will be roughly an additional 2 % lower than its potential GDP . He is also known as the creator of the misery index . - Higher education, post-secondary education, or third level education is an optional final stage of formal learning that occurs after completion of secondary education. Often delivered at universities, academies, colleges, seminaries, and institutes of technology, higher education is also available through certain college-level institutions, including vocational schools, trade schools, and other career colleges that award academic degrees or professional certifications. Tertiary education at non-degree level is sometimes referred to as further education or continuing education as distinct from higher education. - The Ivy League is a collegiate athletic conference comprising sports teams from eight private institutions of higher education in the Northeastern United States. The conference name is also commonly used to refer to those eight schools as a group beyond the sports context. The eight institutions are Brown University, Columbia University, Cornell University, Dartmouth College, Harvard University, the University of Pennsylvania, Princeton University, and Yale University. The term "Ivy League" has connotations of academic excellence, selectivity in admissions, and social elitism. - The Brookings Institution is a century-old American research group on Think Tank Row in Washington, D.C. It conducts research and education in the social sciences, primarily in economics, metropolitan policy, governance, foreign policy, and global economy and development. Its stated mission is to "provide innovative and practical recommendations that advance three broad goals: strengthen American democracy; foster the economic and social welfare, security and opportunity of all Americans; and secure a more open, safe, prosperous, and cooperative international system." - New Haven, in the U.S. state of Connecticut, is the principal municipality in Greater New Haven, which had a total population of 862,477 in 2010. It is located on New Haven Harbor on the northern shore of Long Island Sound in New Haven County, Connecticut, and is part of the New York metropolitan area. It is the second-largest city in Connecticut (after Bridgeport), with a population of 129,779 people as of the 2010 United States Census.

*Question*
Information: - "Decantation" is a process for the separation of mixtures, by removing a layer of liquid, generally one from which a precipitate has settled. The purpose may be either to produce a clean decant, or to remove undesired liquid from the precipitate (or other layers). If the aim is to produce a clean solution, a small amount of solution must generally be left in the container, and care must be taken to prevent any precipitate from flowing with the solution out of the container. - Sediment is a naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of wind, water, or ice, and/or by the force of gravity acting on the particles. For example, sand and silt can be carried in suspension in river water and on reaching the sea be deposited by sedimentation and if buried this may eventually become sandstone and siltstone, (sedimentary rocks). - Glass is a non-crystalline amorphous solid that is often transparent and has widespread practical, technological, and decorative usage in, for example, window panes, tableware, and optoelectronics. The most familiar, and historically the oldest, types of glass are "silicate glasses" based on the chemical compound silica (silicon dioxide, or quartz), the primary constituent of sand. The term "glass", in popular usage, is often used to refer only to this type of material, which is familiar from use as window glass and in glass bottles. Of the many silica-based glasses that exist, ordinary glazing and container glass is formed from a specific type called soda-lime glass, composed of approximately 75% silicon dioxide (SiO), sodium oxide (NaO) from sodium carbonate (NaCO), calcium oxide, also called lime (CaO), and several minor additives. - A decanter is a vessel that is used to hold the decantation of a liquid (such as wine) which may contain sediment. Decanters are normally used as serving vessels for wine. Decanters vary in shape and design. They are made using a variety of materials like glass and crystal. They typically hold at least one standard bottle of wine (0.75 litre). A similar kind of vessel, the carafe , is used for serving wine as well as other drinks, but is not supplied with a stopper. - A carafe / krf / , is a container without handles used for serving wine and other drinks . Unlike the related decanter , carafes do not include stoppers . Coffee pots included in coffee makers are also referred to as carafes in American English . In France , carafes are commonly used to serve water . To order a carafe d'eau ( '' carafe of water '' ) is to request to be served ( free ) tap water rather than bottled water at a cost . - Wine (from Latin "vinum") is an alcoholic beverage made from fermented grapes. These grapes are generally "Vitis vinifera," or a hybrid with "Vitis labrusca" or "Vitis rupestris". Grapes are fermented without the addition of sugars, acids, enzymes, water, or other nutrients. Yeast consumes the sugar in the grapes and converts it to ethanol and carbon dioxide. Different varieties of grapes and strains of yeasts produce different styles of wine. These variations result from the complex interactions between the biochemical development of the grape, the reactions involved in fermentation, the terroir, and the production process. Many countries enact legal appellations intended to define styles and qualities of wine. These typically restrict the geographical origin and permitted varieties of grapes, as well as other aspects of wine production. Given the information above, choose from the list below the object entity that exhibits the relation 'subclass of' with the subject 'carafe'. Choices: - action - alcoholic beverage - amorphous solid - calcium - calcium oxide - carbon - carbonate - chemical compound - container - erosion - ethanol - force - glass - grape - liquid - material - out - process - quartz - sandstone - silicate - sodium carbonate - sugars - suspension - tableware - type - variety - vessel - wind - window - wine
