[Q]: Context: The River Cwmnantcol ( Afon Cwmnantcol in Welsh ) is a river in North Wales . It is about 3 miles long and has its source at the head of Cwm Nantcol below Rhinog Fawr and Y Llethr . It flows north - westwards from its source and joins the Afon Artro at Pentre Gwynfryn ., An ocean (the sea of classical antiquity) is a body of saline water that composes much of a planet's hydrosphere. On Earth, an ocean is one of the major conventional divisions of the World Ocean, which covers almost 71% of its surface. These are, in descending order by area, the Pacific, Atlantic, Indian, Southern (Antarctic), and Arctic Oceans. The word "sea" is often used interchangeably with "ocean" in American English but, strictly speaking, a sea is a body of saline water (generally a division of the world ocean) partly or fully enclosed by land., Wrexham (; ) is a large town in north Wales, between the Welsh mountains and the lower Dee Valley alongside the border with England. In Wrexham County Borough, it is the largest town in north Wales and an administrative, commercial, retail and educational centre., Colwyn Bay is a town, community and seaside resort in Conwy County Borough on the north coast of Wales overlooking the Irish Sea. Eight neighbouring communities are incorporated within its postal district. Established as its own separate parish in 1844 with just a small grouping of homes and farms where the community of Old Colwyn stands today, Colwyn Bay has expanded to become the second-largest community and business centre in the north of Wales as well as the 15th largest in the whole of Wales with the urban statistical area having a population of 31,353 at the 2011 census. (Including Old Colwyn, Rhos-on-Sea, Mochdre and Llysfaen communities]. Locally nicknamed "The Bay"., Shropshire (or ; alternatively Salop; abbreviated, in print only, Shrops; demonym Salopian ) is a county located between West Midlands in England and Wales. It borders Powys and Wrexham in Wales to the west and north-west, Cheshire to the north, Staffordshire to the east, Worcestershire to the south-east and Herefordshire to the south. Shropshire Council was created in 2009, a unitary authority taking over from the previous county council and five district councils. The borough of Telford and Wrekin has been a separate unitary authority since 1998 but continues to be included in the ceremonial county., A lake is an area of variable size filled with water, localized in a basin, that is surrounded by land, apart from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, and therefore are distinct from lagoons, and are also larger and deeper than ponds, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which are usually flowing. Most lakes are fed and drained by rivers and streams., Powys (or ; Welsh: ) is a principal area, local-government county and preserved county in Mid Wales. It is named after the successor Kingdom of Powys, which formed after the Romans withdrew from Britain., Llandudno is a seaside resort, town and community in Conwy County Borough, Wales, located on the Creuddyn peninsula, which protrudes into the Irish Sea. In the 2011 UK census, the community, which includes Penrhyn Bay and Penrhynside, had a population of 20,701. The town's name is derived from its patron saint, Saint Tudno., A sea is a large body of salt water that is surrounded in whole or in part by land. More broadly, "the sea" is the interconnected system of Earth's salty, oceanic watersconsidered as one global ocean or as several principal oceanic divisions. The sea moderates Earth's climate and has important roles in the water cycle, carbon cycle, and nitrogen cycle. Although the sea has been traveled and explored since prehistory, the modern scientific study of the seaoceanographydates broadly to the British "Challenger" expedition of the 1870s. The sea is conventionally divided into up to five large oceanic sectionsincluding the International Hydrographic Organization's four named oceans (the Atlantic, Pacific, Indian, and Arctic) and the Southern Ocean; smaller, second-order sections, such as the Mediterranean, are known as "seas"., England is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west. The Irish Sea lies northwest of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain (which lies in the North Atlantic) in its centre and south; and includes over 100 smaller islands such as the Isles of Scilly, and the Isle of Wight., Wales is a country that is part of the United Kingdom and the island of Great Britain. It is bordered by England to the east, the Irish Sea to the north and west, and the Bristol Channel to the south. It had a population in 2011 of 3,063,456 and has a total area of . Wales has over of coastline and is largely mountainous, with its higher peaks in the north and central areas, including Snowdon, its highest summit. The country lies within the north temperate zone and has a changeable, maritime climate., North Wales is the northernmost unofficial region of Wales. Retail, transport and educational infrastructure are centred on Wrexham, Rhyl, Colwyn Bay, Llandudno and Bangor. It is bordered to the south by the counties of Ceredigion and Powys in Mid Wales, and to the east by the counties of Shropshire in the West Midlands and Cheshire in North West England., 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., Mid Wales (or simply "Y Canolbarth" "The Midlands") is the name given to the central region of Wales. The Mid Wales Regional Committee of the National Assembly for Wales covered the counties of Ceredigion and Powys and the area of Gwynedd that had previously been the district of Meirionydd. A similar definition is used by the BBC. The Wales Spatial Plan defines a region known as "Central Wales" which covers Ceredigion and Powys. If Mid Wales is classed as Ceredigion and Powys, the area would be 6,962 square kilometres (about the size of Cumbria)., A stream is a body of water with a current, confined within a bed and banks. Depending on its location or certain characteristics, a stream may be referred to as a "bayou", "beck", "branch", "brook", "burn", "creek", "crick", "ghyll", "gill", "kill", "lick", "mill race", "race", "rill", "river", "rivulet", "run", "runnel", "streamage", "syke", or "wash"., In hillslope geomorphology, a rill is a shallow channel (no more than a few tens of centimetres deep) cut into soil by the erosive action of flowing water. Similar but smaller incised channels are known as microrills; larger incised channels are known as gullies., Rhyl is a seaside resort town and community in the historic county of Denbighshire, situated on the north east coast of Wales, at the mouth of the River Clwyd (Welsh: "Afon Clwyd"). To the west is the suburb of Kinmel Bay, with the resort of Towyn further west, Prestatyn to the east and Rhuddlan to the south. At the 2011 Census, Rhyl had a population of 25,149.
The conurbation of Abergele-Rhyl-Prestatyn has a population of over 60,000, with Rhyl-Kinmel Bay having 31,229 people., A watercourse is the channel that a flowing body of water follows. In the UK, some aspects of criminal law such as The Rivers (Prevention of Pollution) Act 1951 specify that a watercourse includes those rivers which are dry for part of the year., Cheshire (or ; archaically the County Palatine of Chester; abbreviated Ches.) is a county in North West England, bordering Merseyside and Greater Manchester to the north, Derbyshire to the east, Staffordshire and Shropshire to the south and Wales to the west (bordering Wrexham and Flintshire). Cheshire's county town is Chester; the largest town is Warrington., Ceredigion is a county in Mid Wales. In the Middle Ages, it was a minor kingdom also known for a time as Seisyllwg. Following its Norman conquest, the name was anglicised to Cardigan and then Cardiganshire and it began to be administered as a county in 1282. The county had a population of 75,900 at the 2011 UK census. Its largest town, Aberystwyth, is one of the two administrative centres; the other being Aberaeron. Aberystwyth houses Aberystwyth University, Bronglais Hospital and the National Library of Wales. The inland town of Lampeter houses part of the University of Wales Trinity Saint David. More than half the population speak the Welsh language and the county is considered a centre of Welsh culture., Subject: afon cwmnantcol, Relation: located_in_the_administrative_territorial_entity, Options: (A) aberystwyth (B) bangor (C) banks (D) basin (E) cardigan (F) central (G) central region (H) centre (I) ceredigion (J) cheshire (K) chester (L) conwy (M) denbighshire (N) district (O) earth (P) east (Q) england (R) europe (S) gwynedd (T) isle of wight (U) lakes (V) merseyside (W) north (X) north east (Y) north west (Z) of ([) powys (\) prestatyn (]) rhyl (^) river (_) salt (`) scotland (a) seaside (b) shropshire (c) south (d) syke (e) telford and wrekin (f) time (g) united kingdom (h) wales (i) west midlands (j) wrexham (k) wrexham county borough

It is licensed to Jackson , California , USA , and serves the Sacramento , California , area . The station used to be owned by Adelante Media Group , LLC. On October 21 , 2014 , Adelante announced that it was selling KGRB , its sister stations and its LPTV outlet in Sacramento to Lazer Broadcasting , pending FCC approval The transaction was consummated effective December 31 , 2014 , at a price of $ 2.9 million ., 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., A census is the procedure of systematically acquiring and recording information about the members of a given population. It is a regularly occurring and official count of a particular population. The term is used mostly in connection with national population and housing censuses; other common censuses include agriculture, business, and traffic censuses. The United Nations defines the essential features of population and housing censuses as "individual enumeration, universality within a defined territory, simultaneity and defined periodicity", and recommends that population censuses be taken at least every 10 years. United Nations recommendations also cover census topics to be collected, official definitions, classifications and other useful information to co-ordinate international practice., Sacramento is the capital city of the U.S. state of California and the seat of Sacramento County. It is at the confluence of the Sacramento River and the American River in the northern portion of California's expansive Central Valley. Its estimated 2014 population of 485,199 made it the sixth-largest city in California, and the 35th largest city in the United States. Sacramento is the cultural and economic core of the Sacramento metropolitan area, which includes seven counties with a 2010 population of 2,414,783. Its metropolitan area is the fourth largest in California after the Greater Los Angeles area, the San Francisco Bay Area, and the San Diego metropolitan area, and is the 27th largest in the United States. In 2002, the Civil Rights Project at Harvard University conducted for "Time" magazine named Sacramento "America's Most Diverse City"., The Sacramento River is the principal river of Northern California in the United States, and is the largest river in California. Rising in the Klamath Mountains, the river flows south for before reaching the SacramentoSan Joaquin River Delta and San Francisco Bay. The river drains about in 19 California counties, mostly within the fertile agricultural region bounded by the Coast Ranges and Sierra Nevada known as the Sacramento Valley, but also extending as far as the volcanic plateaus of Northeastern California. Historically, its watershed has reached as far north as south-central Oregon where the now, primarily, endorheic (closed) Goose Lake rarely experiences southerly outflow into the Pit River, the most northerly tributary of the Sacramento., A radio station is a set of equipment necessary to carry on communication via radio waves. Generally, it is a receiver or transmitter, an antenna, and some smaller additional equipment necessary to operate them. Radio stations play a vital role in communication technology as they are heavily relied on to transfer data and information across the world., Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. Radio waves have frequencies as high as 300 GHz to as low as 3 kHz, though some definitions describe waves above 1 or 3 GHz as microwaves, or include waves of any lower frequency. At 300 GHz, the corresponding wavelength is , and at 3 kHz is . Like all other electromagnetic waves, they travel at the speed of light. Naturally occurring radio waves are generated by lightning, or by astronomical objects. , The San Francisco Bay Area (referred to locally as the Bay Area) is a populous region surrounding the San Francisco and San Pablo estuaries in Northern California. The region encompasses the major cities and metropolitan areas of San Jose, San Francisco, and Oakland, along with smaller urban and rural areas. The Bay Area's nine counties are Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, Solano, and Sonoma. Home to approximately 7.65 million people, the nine-county Bay Area contains many cities, towns, airports, and associated regional, state, and national parks, connected by a network of roads, highways, railroads, bridges, tunnels and commuter rail. The combined statistical area of the region is the second-largest in California (after the Greater Los Angeles area), the fifth-largest in the United States, and the 43rd-largest urban area in the world., Jackson (formerly, Botilleas, Botilleas Spring, Bottileas, Bottle Spring, and Botellas) is the county seat of Amador County, California. The population was 4,651 at the 2010 census, up from 3,989 at the 2000 census. The city is accessible by both State Route 49 and State Route 88., Amador County, officially the County of Amador, is a county in the U.S. state of California, in the Sierra Nevada. As of the 2010 census, the population was 38,091. The county seat is Jackson., The American River (Río de los Americanos during the Mexican-ruled period before 1846) is a 119 mile long California river which runs from the Sierra Nevada mountain range to its confluence with the Sacramento River in the Sacramento Valley. Via the Sacramento River, it is part of the San Francisco Bay and Pacific Ocean watershed. The river is fed by the melting snowpack of the Sierra Nevada and its many headwaters and tributaries, including the North, Middle, and South Forks., Subject: kgrb , Relation: inception, Options: (A) 10 (B) 1636 (C) 1846 (D) 19 (E) 2 (F) 2000 (G) 2002 (H) 2010 (I) 2014 (J) 300 (K) 4 (L) 7

[Q]: Context: Astronomy is a natural science that studies celestial objects and phenomena. It applies mathematics, physics, and chemistry, in an effort to explain the origin of those objects and phenomena and their evolution. Objects of interest include planets, moons, stars, galaxies, and comets; while the phenomena include supernovae explosions, gamma ray bursts, and cosmic microwave background radiation. More generally, all astronomical phenomena that originate outside Earth's atmosphere are within the purview of astronomy. A related but distinct subject, physical cosmology, is concerned with the study of the Universe as a whole., In physics, the wavelength of a sinusoidal wave is the spatial period of the wavethe distance over which the wave's shape repeats, 
and thus the inverse of the spatial frequency. It is usually determined by considering the distance between consecutive corresponding points of the same phase, such as crests, troughs, or zero crossings and is a characteristic of both traveling waves and standing waves, as well as other spatial wave patterns. 
Wavelength is commonly designated by the Greek letter "lambda" (). The concept can also be applied to periodic waves of non-sinusoidal shape. 
The term "wavelength" is also sometimes applied to modulated waves, and to the sinusoidal envelopes of modulated waves or waves formed by interference of several sinusoids., The James Clerk Maxwell Telescope (JCMT) is a submillimetre-wavelength telescope at Mauna Kea Observatory in Hawaii. The telescope is near the summit of Mauna Kea at . Its primary mirror is 15 metres (16.4 yards) across: it is the largest single-dish telescope that operates in submillimetre wavelengths of the electromagnetic spectrum (far-infrared to microwave). Scientists use it to study the Solar System, interstellar dust and gas, and distant galaxies., Mauna Kea (or ), is a dormant volcano on the island of Hawaii. Standing above sea level, its peak is the highest point in the state of Hawaii. Much of the mountain is under water; when measured from its oceanic base, Mauna Kea is over tall. Mauna Kea is about a million years old, and has thus passed the most active shield stage of life hundreds of thousands of years ago. In its current post-shield state, its lava is more viscous, resulting in a steeper profile. Late volcanism has also given it a much rougher appearance than its neighboring volcanoes; contributing factors include the construction of cinder cones, the decentralization of its rift zones, the glaciation on its peak, and the weathering effects of the prevailing trade winds. Mauna Kea last erupted 6,000 to 4,000 years ago and is now considered dormant., The Solar System is the gravitationally bound system comprising the Sun and the objects that orbit it, either directly or indirectly. Of those objects that orbit the Sun directly, the largest eight are the planets, with the remainder being significantly smaller objects, such as dwarf planets and small Solar System bodies. Of the objects that orbit the Sun indirectly, the moons, two are larger than the smallest planet, Mercury., Terahertz radiation  also known as submillimeter radiation, terahertz waves, tremendously high frequency, T-rays, T-waves, T-light, T-lux or THz  consists of electromagnetic waves within the ITU-designated band of frequencies from 0.3 to 3 terahertz (THz; 10 Hz). Wavelengths of radiation in the terahertz band correspondingly range from 1 mm to 0.1 mm (or 100 m). Because terahertz radiation begins at a wavelength of one millimeter and proceeds into shorter wavelengths, it is sometimes known as the "submillimeter band", and its radiation as "submillimeter waves", especially in astronomy., Hawaii is the 50th and most recent state to have joined the United States of America, having received statehood on August 21, 1959. Hawaii is the only U.S. state located in Oceania and the only one composed entirely of islands. It is the northernmost island group in Polynesia, occupying most of an archipelago in the central Pacific Ocean. Hawaii is the only U.S. state not located in the Americas., Microwaves are a form of electromagnetic radiation with wavelengths ranging from one meter to one millimeter; with frequencies between and . This broad definition includes both UHF and EHF (millimeter wave) bands, and various sources use different boundaries. In all cases, microwaves include the entire SHF band (3 to 30 GHz, or 10 to 1 cm) at minimum, with RF engineering often restricting the range between 1 and 100 GHz (300 and 3 mm). Frequencies in the microwave range are often referred to by their IEEE radar band designations: S, C, X, K, K, or K band, or by similar NATO or EU designations., 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., The Netherlands  is the main constituent country of the Kingdom of the Netherlands. It is a densely populated country located in Western Europe with three island territories in the Caribbean. The European part of the Netherlands borders Germany to the east, Belgium to the south, and the North Sea to the northwest, sharing maritime borders with Belgium, the United Kingdom, and Germany. The largest cities in the Netherlands are Amsterdam, Rotterdam, The Hague and Utrecht. Amsterdam is the country's capital, while The Hague holds the Dutch seat of government and parliament. The name "Holland" is used to refer informally to the whole of the country of the Netherlands., A telescope is an optical instrument that aids in the observation of remote objects by collecting electromagnetic radiation (such as visible light). The first known practical telescopes were invented in the Netherlands at the beginning of the 1600s, by using glass lenses. They found use in both terrestrial applications and astronomy. , The Caltech Submillimeter Observatory ( CSO ) is a 10.4 - meter ( 34 ft ) diameter submillimeter wavelength telescope situated alongside the 15 - meter ( 49 ft ) James Clerk Maxwell Telescope ( JCMT ) at Mauna Kea Observatory . It is engaged in submillimeter astronomy , of the terahertz radiation band . The telescope is set to be decommissioned in the near future as part of the Mauna Kea Comprehensive Management Plan ., In physics, electromagnetic radiation (EM radiation or EMR) refers to the waves (or their quanta, photons) of the electromagnetic field, propagating (radiating) through space carrying electromagnetic radiant energy. It includes radio waves, microwaves, infrared, (visible) light, ultraviolet, X-, and gamma radiation., Subject: caltech submillimeter observatory, Relation: located_in_the_administrative_territorial_entity, Options: (A) amsterdam (B) belgium (C) caribbean (D) eu (E) hawaii (F) kea (G) mercury (H) most (I) netherlands (J) north (K) observatory (L) of (M) pacific ocean (N) rotterdam (O) south (P) summit (Q) united states of america
