Example Input: Context_1 : Ages and Ages is an American rock band from Portland, Oregon which has been receiving positive critical attention because of their upbeat "raw choral pop" sound. Every member of the band sings accompanied by handclaps, shakers and noise-makers. They are a secular band with a big tent revival sound. The group was voted as a top Portland band by "Willamette Week". In 2011, they signed a record deal with Partisan Records and have since undertaken several national US tours. In 2013 the band changed their name from AgesandAges to Ages and Ages. The rechristened band played their first European dates in the winter of 2014. Context_2 : Bristeil is an independent band, which playing in indie rock style, although they call their music style as intelligent rock and located in Minsk, Belarus. The band sings euphonic rock songs in the Belarusian language. The band was formed in 2013 year by frontman Hair Peace Salon band Aleh Vial, which considered as one of the best rock performers in Belarus. They released their debut EP, "Cyruĺnia Svietu" ("Barbershop of the World" into English), on 26 May 2014. Context_3 : Orquesta de la Luz (オルケスタ・デ・ラ・ルス ) ("Orchestra of the Light") is a Japanese salsa band that was formed in 1984 and began performing and recording in 1990. The band sings in Spanish (although the majority of the group doesn't know what they are singing), and is led by vocalist Nora, who returned to traditional salsa after the band broke up in the mid-1990s. It became widely famous in Latin America, particularly in Colombia, Puerto Rico, Panama, Mexico, Perú and other Caribbean area countries. The Japanese salsa band Orquesta de La Luz was quite a large one, whose main focal point (and only consistent member throughout their tenure together) was singer Nora. Throughout the years, Nora was joined by a rotating cast of musicians in the group, including Gen Ogimi, percussion; Carlos Kanno, percussion; Genichi Egawa, timbales; Gen Date, conga; Hiroshi Sawada, bass; Satoru Shoinoya, piano, keyboards; Shiro Sasaki, trumpet; Tatsuya Shimogami, trumpet; Yoshihito Fukumoto, trumpet; Hideaki Nakaji, trombone; and Taisei Aoki, trombone, while co-producer/arranger Sergio George contributed keyboards from time to time. The group built a substantial following in their homeland during the early to mid-'90s (with such releases as 1990's Orquesta de La Luz, 1991's Sin Fronteras, and 1992's Somos Diferentes), before switching their sound primarily to jazz and ballads. By 1995, Orquesta de La Luz had broken up, with Nora launching a solo career shortly thereafter (and returning to her former band's early salsa sound). Context_4 : Guilty Pleasures is a 2007 album by the band Lazlo Bane, consisting entirely of cover versions of various hits from the 1970s. Unlike the band's previous album, "Back Sides", which was released only digitally through online music stores, "Guilty Pleasures" was released both on CD and digital download formats. It is also the first and only Lazlo Bane album where every member of the band sings lead vocals on at least one song. Context_5 : "Special K" is a single by British alternative rock band Placebo, released on 19 March 2001 on CD and 12" vinyl, taken from their third album, "Black Market Music". The title is slang for Ketamine, and the song itself is supposed to explore "the link between drugs and love," and ""Special K" is uppers and the rush of falling in love." Context_6 : The Bolts are an independent modern rock band from Irvine, California. Formed in 2007, the band consists of guitarist Heath Farmer, bassist Addam Farmer, keyboardist Austin Farmer, guitarist Ryan Kilpatrick, and drummer Matt Champagne. The entire frontline of the band sings lead vocals with multiple harmony. Context_7 : Progres 2 is an art rock band from Brno, Czech Republic. It was established in 1968, known as Progress Organization, by Zdeněk Kluka, Pavel Váně, Jan Sochor and Emanuel Sideridis. Its most important album in a Czech context was the rock opera project "Dialog s vesmírem" (Dialog with The Universe) in 1978, only a year after the transformation of the band called "Bardonaj" to the new band Progres 2. The public presentation of this rock opera was the first audiovisual program of rock music in Czechoslovakia, inspired by the British rock group Pink Floyd. Because this rock band played in the totalitarian state, they had a few troubles with officials. The best known problem was the one with lyrics of one song from the album "Dialog s vesmírem". The song was called "Planeta Hieronyma Bosche" (The Planet of Hieronymus Bosch) where the band sings about life on heroin. Censors forbade this song and the band solved it by using only the vowels from the original lyrics. At concerts they played the whole original lyrics. Context_8 : Ketamine, sold under the brand name Ketalar among others, is a medication mainly used for starting and maintaining anesthesia. It induces a trance-like state while providing pain relief, sedation, and memory loss. Other uses include for chronic pain and for sedation in intensive care. Heart function, breathing, and airway reflexes generally remain functional during its effects. Effects typically begin within five minutes when given by injection with the main effects lasting up to 25 minutes. Context_9 : Los 5 stylized as LOS 5 is an independent multi-ethnic Latin musical pop/rap band based in Los Angeles with members originating from Mexico, Argentina and Brazil and now based in the United States. The lead musical vocals is by Juan Pablo Casillas and the rap parts are performed by Matt Rey. The band sings in English and Spanish. Most members met when they were studying music at Hollywood's Musician's Institute forming the band The Wavelength. The band is managed by talent executive Terry Anzaldo. Consequently the band was renamed LOS 5. Context_10 : Three's a Crowd is an American animated short film. It is a "Merrie Melody" cartoon, released on December 10, 1932, although one source gives it a release date of January 17, 1933.

Example Input: Context_1 : The epidermis (from the Greek "ἐπιδερμίς", meaning "over-skin") is a single layer of cells that covers the leaves, flowers, roots and stems of plants. It forms a boundary between the plant and the external environment. The epidermis serves several functions: it protects against water loss, regulates gas exchange, secretes metabolic compounds, and (especially in roots) absorbs water and mineral nutrients. The epidermis of most leaves shows dorsoventral anatomy: the upper (adaxial) and lower (abaxial) surfaces have somewhat different construction and may serve different functions. Woody stems and some other stem structures produce a secondary covering called the periderm that replaces the epidermis as the protective covering. Context_2 : A lenticel is a porous tissue consisting of cells with large intercellular spaces in the periderm of the secondarily thickened organs and the bark of woody stems and roots of dicotyledonous flowering plants. It functions as a pore, providing a pathway for the direct exchange of gases between the internal tissues and atmosphere through the bark, which is otherwise impermeable to gases. The name lenticel, pronounced with an s] , derives from its lenticular (lens-like) shape. The shape of lenticels is one of the characteristics used for tree identification. Context_3 : Homoiohydry is the capacity of plants to regulate, or achieve homeostasis of, cell and tissue water content. Homoiohydry evolved in land plants to a lesser or greater degree during their transition to land more than 500 million years ago, and is most highly developed in the vascular plants. It is the consequence of a suite of morphological innovations and strategies that enable plant shoots exploring aerial environments to conserve water by internalising the gas exchange surfaces, enclosing them in a waterproof membrane and providing a variable aperture control mechanism, the stomatal guard cells, which regulate the rates of water transpiration and CO exchange. In vascular plants, water is acquired from the soil by roots and transported via the xylem to aerial portions of the plant. Water evaporation from the aerial surfaces of the plant is controlled by a waterproof covering of cuticle. Gas exchange with the atmosphere is controlled by stomata, which can open and close to control water loss, and diffusion of carbon dioxide to the chloroplasts takes place in intercellular spaces between chlorenchyma cells in the stem or in the mesophyll tissue of the leaf. Context_4 : A stoma is a pore, found in the epidermis of leaves, stems, and other organs, that facilitates gas exchange. Context_5 : Guard cells are specialized cells in the epidermis of leaves, stems and other organs that are used to control gas exchange. They are produced in pairs with a gap between them that forms a stomatal pore. The stomatal pores are largest when water is freely available and the guard cells turgid, and closed when water availability is critically low and the guard cells become flaccid. Photosynthesis depends on the diffusion of carbon dioxide (CO) from the air through the stomata into the mesophyll tissues. Oxygen (O), produced as a byproduct of photosynthesis, exits the plant via the stomata. When the stomata are open, water is lost by evaporation and must be replaced via the transpiration stream, with water taken up by the roots. Plants must balance the amount of CO absorbed from the air with the water loss through the stomatal pores, and this is achieved by both active and passive control of guard cell turgor and stomatal pore size. Context_6 : An integrated fluorometer is a system that measures the light reaction and the dark reaction of photosynthesis. Software allows combined operation of gas exchange measurement and chlorophyll fluorescence measurement of a leaf. These parameters are used to non-destructively measure the photosynthetic efficiency of plants. The use of an integrated chlorophyll fluorometer provides the opportunity to measure additional measuring parameters that allow for a more exact measurement of photosynthesis than with gas exchange alone. Advanced gas exchange instrumentation, by itself, is capable of measuring A/Ci curves, commonly used for plant characterization. “A” is the term for photosynthetic rate (rate of CO exchange in the leaf chamber), and Ci is Sub-stomatal CO concentration or intracellular CO level within the leaf. When measured over a range of CO levels above and below ambient conditions, A/Ci curves become possible. With the addition of an integrated chlorophyll fluorometer, it becomes possible to measure more accurate A/C curves, or photosynthetic rate at the site of carboxylation in chloroplasts. The integrated fluorometer allows measurement of mesophyll conductance, or the opposite of the resistance to CO transfer from intracellular air spaces to the site of carboxylation in chloroplasts. Various integrated chlorophyll fluorometer measuring protocols, such as the Laisk Protocol, the Kok protocol and the Yin Protocol are used to measure or estimate g or mesophyll conductance. For example: the Laisk protocol allows the measurement of Γ* or compensation point, and R or respiration in the dark. Both values are required to calculate g or mesophyll conductance and C or CO at the site of carboxylation. Parameters typically measured by the gas exchange portion of the system include: “A” or photosynthetic rate, “gs” or stomatal conductance, “Ci” or sub stomatal CO concentration, and “E” or transpiration. Context_7 : The soil-plant-atmosphere continuum (SPAC) is the pathway for water moving from soil through plants to the atmosphere. Continuum in the description highlights the continuous nature of water connection through the pathway. The low water potential of the atmosphere, and relatively higher (i.e. less negative) water potential inside leaves, leads to a diffusion gradient across the stomatal pores of leaves, drawing water out of the leaves as vapour. As water vapour transpires out of the leaf, further water molecules evaporate off the surface of mesophyll cells to replace the lost molecules since water in the air inside leaves is maintained at saturation vapour pressure. Water lost at the surface of cells is replaced by water from the xylem, which due to the cohesion-tension properties of water in the xylem of plants pulls additional water molecules through the xylem from the roots toward the leaf. Context_8 : An alveolus (plural: alveoli, from Latin "alveolus", "little cavity") is a hollow cavity found in the lung parenchyma, and is the basic unit of respiration. Lung alveoli are the ends of the respiratory tree, branching from either alveolar sacs or alveolar ducts, which like alveoli are both sites of gas exchange with the blood as well. Alveoli are particular to mammalian lungs. Different structures are involved in gas exchange in other vertebrates. The alveolar membrane is the gas exchange surface. Carbon dioxide rich blood is pumped from the rest of the body into the capillaries that surround the alveoli where, through diffusion, carbon dioxide is released and oxygen absorbed. Context_9 : In botany, a stoma (plural "stomata"), also called a stomate (plural "stomates") (from Greek στόμα, "mouth"), is a pore, found in the epidermis of leaves, stems, and other organs, that facilitates gas exchange. The pore is bordered by a pair of specialized parenchyma cells known as guard cells that are responsible for regulating the size of the stomatal opening. Context_10 : Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. The remaining 97–99.5% is lost by transpiration and guttation. Leaf surfaces are dotted with pores called stomata, and in most plants they are more numerous on the undersides of the foliage. The stomata are bordered by guard cells and their stomatal accessory cells (together known as stomatal complex) that open and close the pore. Transpiration occurs through the stomatal apertures, and can be thought of as a necessary "cost" associated with the opening of the stomata to allow the diffusion of carbon dioxide gas from the air for photosynthesis. Transpiration also cools plants, changes osmotic pressure of cells, and enables mass flow of mineral nutrients and water from roots to shoots. Two major factors influence the rate of water flow from the soil to the roots: the hydraulic conductivity of the soil and the magnitude of the pressure gradient through the soil. Both of these factors influence the rate of bulk flow of water moving from the roots to the stomatal pores in the leaves via the xylem. fact_1 : The soil-plant-atmosphere continuum (SPAC) is the pathway for water moving from soil through plants to the atmosphere. fact_2 : In botany, a stoma (plural "stomata"), also called a stomate (plural "stomates") (from Greek στόμα, "mouth"), is a pore, found in the epidermis of leaves, stems, and other organs, that facilitates gas exchange.
