Example Input: Context: The scientific method is a body of techniques for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge. To be termed scientific, a method of inquiry is commonly based on empirical or measurable evidence subject to specific principles of reasoning. The Oxford Dictionaries Online define the scientific method as "a method or procedure that has characterized natural science since the 17th century, consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses". Experiments need to be designed to test hypotheses. The most important part of the scientific method is the experiment., 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., Education is the process of facilitating learning, or the acquisition of knowledge, skills, values, beliefs, and habits. Educational methods include storytelling, discussion, teaching, training, and directed research. Education frequently takes place under the guidance of educators, but learners may also educate themselves. Education can take place in formal or informal settings and any experience that has a formative effect on the way one thinks, feels, or acts may be considered educational. The methodology of teaching is called pedagogy., A planetary nebula, often abbreviated as PN or plural PNe, is a kind of emission nebula consisting of an expanding, glowing shell of ionized gas ejected from old red giant stars late in their lives. The word "nebula" is Latin for mist or cloud, and the term "planetary nebula" is a misnomer that originated in the 1780s with astronomer William Herschel because when viewed through his telescope, these objects resemble the rounded shapes of planets. Herschel's name for these objects was popularly adopted and has not been changed. They are a relatively short-lived phenomenon, lasting a few tens of thousands of years, compared to a typical stellar lifetime of several billion years., Human science is the study and interpretation of the experiences, activities, constructs, and artifacts associated with human beings. The study of the human sciences attempts to expand and enlighten the human being's knowledge of their existence, its interrelationship with other species and systems, and the development of artifacts to perpetuate the human expression and thought. It is the study of human phenomena. The study of the human experience is historical and current in nature. It requires the evaluation and interpretation of the historic human experience and the analysis of current human activity to gain an understanding of human phenomena and to project the outlines of human evolution. Human science is the objective, informed critique of human existence and how it relates to reality., An emission nebula is a nebula formed of ionized gases that emit light of various colors. The most common source of ionization is high-energy photons emitted from a nearby hot star. Among the several different types of emission nebulae are H II regions, in which star formation is taking place and young, massive stars are the source of the ionizing photons; and planetary nebulae, in which a dying star has thrown off its outer layers, with the exposed hot core then ionizing them., Pedagogy is the discipline that deals with the theory and practice of education; it thus concerns the study of how best to teach. Spanning a broad range of practice, its aims range from furthering liberal education (the general development of human potential) to the narrower specifics of vocational education (the imparting and acquisition of specific skills)., Social science is a major category of academic disciplines, concerned with society and the relationships among individuals within a society. It in turn has many branches, each of which is considered a "social science". The main social sciences include economics, political science, human geography, demography, and sociology. In a wider sense, social science also includes some fields in the humanities such as anthropology, archaeology, jurisprudence, history, and linguistics. The term is also sometimes used to refer specifically to the field of sociology, the original 'science of society', established in the 19th century. A more detailed list of sub-disciplines within the social sciences can be found at Outline of social science., Harvard University is a private Ivy League research university in Cambridge, Massachusetts, established in 1636, whose history, influence, and wealth have made it one of the world's most prestigious universities., Science education is the field concerned with sharing science content and process with individuals not traditionally considered part of the scientific community. The learners may be children, college students, or adults within the general public; the field of science education includes work in science content, science process (the scientific method), some social science, and some teaching pedagogy. The standards for science education provide expectations for the development of understanding for students through the entire course of their K-12 education and beyond. The traditional subjects included in the standards are physical, life, earth, space, and human sciences., Eric J. Chaisson is an American astrophysicist best known for his research , teaching , and writing on the interdisciplinary science of cosmic evolution , a large public - domain web site for which can be accessed here . ( Closely related subjects include epic of evolution , big history , and astrobiology ) . He is also noted for his telescopic observations of interstellar clouds and emission nebulae of the Milky Way Galaxy , his empirical attempt to unify complexity science utilizing the technical concept of energy rate density , and his global leadership in improving science education nationally and internationally . He conducts research at the Harvard - Smithsonian Center for Astrophysics and teaches natural science at Harvard University ., A research university is a university that expects all its tenured and tenure-track faculty to continuously engage in research, as opposed to merely requiring it as a condition of an initial appointment or tenure. Such universities can be recognized by their strong focus on innovative research and the prestige of their brand names. On the one hand, research universities strive to recruit faculty who are the most brilliant minds in their disciplines in the world, and their students enjoy the opportunity to learn from such experts. On the other hand, new students are often disappointed to realize their undergraduate courses at research universities are overly academic and fail to provide vocational training with immediate "real world" applications; but many employers value degrees from research universities because they know that such coursework develops fundamental skills like critical thinking. , Subject: eric chaisson, Relation: occupation, Options: (A) academic (B) astronomer (C) faculty (D) jurisprudence (E) major (F) pedagogy (G) research (H) science
Example Output: astronomer

Example Input: Context: Kim Il-sung Square is a large city square in the Central District of Pyongyang, North Korea, and is named after the country's founding leader, Kim Il-sung. The square was constructed in 1954 according to a master plan for reconstructing the capital after the destruction of the Korean War. It was opened in August 1954. The square is located on the foot of the Namsan Hill, west bank of the Taedong River, directly opposite the "Juche" Tower on the other side of the river. It is the 37th largest square in the world, having an area of about 75,000 square meters (807,293 square feet) which can accommodate a rally of more than 100,000 people. The square has a great cultural significance, as it is a common gathering place for rallies, dances and military parades and is often featured in media concerning the DPRK., China, officially the People's Republic of China (PRC), is a unitary sovereign state in East Asia. With a population of over 1.381 billion, it is the world's most populous country. The state is governed by the Communist Party of China, and its capital is Beijing. It exercises jurisdiction over 22 provinces, five autonomous regions, four direct-controlled municipalities (Beijing, Tianjin, Shanghai, and Chongqing), and two mostly self-governing special administrative regions (Hong Kong and Macau), and claims sovereignty over Taiwan. The country's major urban areas include Shanghai, Guangzhou, Beijing, Chongqing, Shenzhen, Tianjin and Hong Kong. China is a great power and a major regional power within Asia, and has been characterized as a potential superpower., The Korean Peninsula is a peninsula in East Asia. It extends southwards for about from continental Asia into the Pacific Ocean and is surrounded by the Sea of Japan (East Sea) to the east, and the Yellow Sea (West Sea) to the west, the Korea Strait connecting the first two bodies of water., East Asia is the eastern subregion of the Asian continent, which can be defined in either geographical or ethno-cultural terms. Geographically and geopolitically, it includes China, Hong Kong, and Macao; Mongolia and Taiwan; North and South Korea; and Japan; it covers about , or about 28% of the Asian continent, about twice the area of Europe., The Rangnim Mountains are a mountain range stretching from north to south, west of the Kaema Highlands, in central North Korea. They are the source of several major rivers of North Korea, such as the Taedong and the Ch'ngch'n. The mountain range is generally highest in the east, and falls towards the west. Its highest peak is Wagalbong, at 2,260 m. , Pyongyang ((), , literally: "Flat Land" or "Peaceful Land") is the capital and largest city of the Democratic Peoples Republic of Korea (commonly known as North Korea)., A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as stream, creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague., North Korea, officially the Democratic People's Republic of Korea (DPRK ), is a country in East Asia, in the northern part of the Korean Peninsula. Pyongyang is both the nation's capital as well as its largest city. To the north and northwest the country is bordered by China and by Russia along the Amnok (known as the Yalu in China) and Tumen rivers. The country is bordered to the south by South Korea, with the heavily fortified Korean Demilitarized Zone (DMZ) separating the two., The Korean Demilitarized Zone (DMZ) is a highly militarized strip of land running across the Korean Peninsula. It was established at the end of the Korean War to serve as a buffer zone between the Democratic People's Republic of Korea (North Korea) and the Republic of Korea (South Korea). The DMZ is a "de facto" border barrier that divides the Korean Peninsula roughly in half. It was created by agreement between North Korea, China and the United Nations in 1953. The DMZ is long, and about wide., The "Juche" Tower (more formally, Tower of the "Juche" Idea) is a monument in Pyongyang, the capital of North Korea, named after the ideology of "Juche" introduced by its first leader Kim Il-sung., South Korea, officially the Republic of Korea (ROK), is a sovereign state in East Asia, constituting the southern part of the Korean Peninsula., Tongdaewn-guyk or Tongdaewon District is one of the 20 wards, and one of the six that constitute East Pyongyang, North Korea.

Example Input: Context: A frond is a large, divided leaf. In both common usage and botanical nomenclature, the leaves of ferns are referred to as fronds and some botanists restrict the term to this group. Other botanists allow the term frond to also apply to the large leaves of cycads and palms (Arecaceae). "Frond" is commonly used to identify a large, compound leaf, but if the term is used botanically to refer to the leaves of ferns, it may be applied to smaller and undivided leaves., A fern is a member of a group of about 10,560 known extant species of vascular plants that reproduce via spores and have neither seeds nor flowers. They differ from mosses by being vascular, i.e., having certain tissue that conducts water and nutrients. They have branched stems and leaves like other vascular plants. These are "megaphylls", which are more complex than the simple "microphylls" of clubmosses. Most ferns are Leptosporangiate ferns, sometimes denominated the "true ferns": they produce what are called "fiddleheads" that uncoil and expand into fronds., The Permian is a geologic period and system which spans 46.7 million years from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic Period 252.2 Mya. It is the last period of the Paleozoic Era; the following Triassic Period belongs to the Mesozoic Era. The concept of the Permian was introduced in 1841 by geologist Sir Roderick Murchison, who named it after the city of Perm., The Carboniferous is a geologic period and system that spans 60 million years from the end of the Devonian Period million years ago (Mya), to the beginning of the Permian Period, Mya. The name "Carboniferous" means "coal-bearing" and derives from the Latin words "carb" ("coal") and "fer" ("I bear, I carry"), and was coined by geologists William Conybeare and William Phillips in 1822. Based on a study of the British rock succession, it was the first of the modern 'system' names to be employed, and reflects the fact that many coal beds were formed globally during that time. The Carboniferous is often treated in North America as two geological periods, the earlier Mississippian and the later Pennsylvanian., Glossopteridales is an extinct order of plants belonging to Pteridospermatophyta, or seed ferns, also known as Arberiales and Ottokariales. They arose at the beginning of the Permian on the southern continent of Gondwana, but became extinct before the end of the Permian period. The best known genus is "Glossopteris". Other examples are Glossotheca and Vertebraria, Gangamopteris is a genus of Carboniferous - Permian , very similar to Glossopteris . Previously , it was classified as fern with reproduction by seed . The genus is usually only applied to leaves , making it an form taxon . Gangamopteris dominates some coal deposits , such as those of the Beacon Supergroup . In Paleorrota geopark in Rio Grande do Sul , Brazil , were found Gangamopteris obovata . Were located on the Mina Morro do Papaléo in Mariana Pimentel and Quitéria in Pantano Grande . Dating from the Permian and were in the Rio Bonito Formation . In the town of Cachoeira do Sul , met Gangamopteris sulriograndensis were discovered ., Glossopteris (, meaning "tongue", because the leaves were tongue-shaped) is the largest and best-known genus of the extinct order of seed ferns known as Glossopteridales (also known as Arberiales or Ottokariales). The genus "Glossopteris" refers only to leaves, within a framework of form genera used in paleobotany. For likely reproductive organs see Glossopteridaceae, and these are important because they indicate biological identity of these plants that were critical for recognizing former connections between the varied fragments of Gondwana: South America, Africa, India, Australia, New Zealand, and Antarctica., The Beacon Supergroup is a geological formation exposed in Antarctica and deposited from the Devonian to the Triassic. The unit was originally described as either a formation or sandstone, and upgraded to group and supergroup as time passed. It contains a sandy member known as the Beacon heights orthoquartzite.
Setting in time and space.
Named after Beacon Heights. First named 1907, type section described in 1963. Originally dubbed a formation, with scope left (and later used) to expand to group, then supergroup, as better mapped and understood. Beacon Dome at the head of Griffith Glacier is named after the Beacon Supergroup., The Devonian is a geologic period and system of the Paleozoic, spanning 60 million years from the end of the Silurian, million years ago (Mya), to the beginning of the Carboniferous, Mya. It is named after Devon, England, where rocks from this period were first studied.
The first significant adaptive radiation of life on dry land occurred during the Devonian. Free-sporing vascular plants began to spread across dry land, forming extensive forests which covered the continents. By the middle of the Devonian, several groups of plants had evolved leaves and true roots, and by the end of the period the first seed-bearing plants appeared. Various terrestrial arthropods also became well-established. Fish reached substantial diversity during this time, leading the Devonian to often be dubbed the "Age of Fish". The first ray-finned and lobe-finned bony fish appeared, while the placodermi began dominating almost every known aquatic environment., Vascular plants (from Latin "vasculum": duct), also known as tracheophytes (from the equivalent Greek term "trachea") and also higher plants, form a large group of plants (c. 308,312 accepted known species ) that are defined as those land plants that have lignified tissues (the xylem) for conducting water and minerals throughout the plant. They also have a specialized non-lignified tissue (the phloem) to conduct products of photosynthesis. Vascular plants include the clubmosses, horsetails, ferns, gymnosperms (including conifers) and angiosperms (flowering plants). Scientific names for the group include Tracheophyta and Tracheobionta., Australia, officially the Commonwealth of Australia, is a country comprising the mainland of the Australian continent, the island of Tasmania and numerous smaller islands. It is the world's sixth-largest country by total area. The neighbouring countries are Papua New Guinea, Indonesia and East Timor to the north; the Solomon Islands and Vanuatu to the north-east; and New Zealand to the south-east. Australia's capital is Canberra, and its largest urban area is Sydney., Africa is the world's second-largest and second-most-populous continent. At about 30.3 million km² (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20.4 % of its total land area. With 1.1 billion people as of 2013, it accounts for about 15% of the world's human population. The continent is surrounded by the Mediterranean Sea to the north, both the Suez Canal and the Red Sea along the Sinai Peninsula to the northeast, the Indian Ocean to the southeast, and the Atlantic Ocean to the west. The continent includes Madagascar and various archipelagos. It contains 54 fully recognized sovereign states (countries), nine territories and two "de facto" independent states with limited or no recognition., The Triassic is a geologic period and system which spans 50.9 million years from the end of the Permian Period million years ago (Mya), to the beginning of the Jurassic Period Mya. The Triassic is the first period of the Mesozoic Era. Both the start and end of the period are marked by major extinction events. The Triassic was named in 1834 by Friedrich von Alberti, after the three distinct rock layers ("tri" meaning "three") that are found throughout Germany and northwestern Europered beds, capped by marine limestone, followed by a series of terrestrial mud- and sandstonescalled the "Trias"., India, officially the Republic of India ("Bhrat Gaarjya"), is a country in South Asia. It is the seventh-largest country by area, the second-most populous country (with over 1.2 billion people), and the most populous democracy in the world. It is bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast. It shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the northeast; and Myanmar (Burma) and Bangladesh to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives. India's Andaman and Nicobar Islands share a maritime border with Thailand and Indonesia.
