Answer: 2001
Agricultural extension is the application of scientific research and new knowledge to agricultural practices through farmer education. The field of 'extension' now encompasses a wider range of communication and learning activities organized for rural people by educators from different disciplines, including agriculture, agricultural marketing, health, and business studies.

Question: What does the field of extension encompass?
Answer: a wider range of communication and learning activities
Drinking water quality has a micro-biological and a physico-chemical dimension. There are thousands of parameters of water quality. In public water supply systems water should, at a minimum, be disinfected—most commonly through the use of chlorination or the use of ultra violet light—or it may need to undergo treatment, especially in the case of surface water. For more details, please see the separate entries on water quality, water treatment and drinking water.

Question: How is water in supply systems most commonly disinfected?
Answer: the use of chlorination or the use of ultra violet light
Some water utilities provide only water supply services, while sewerage is under the responsibility of a different entity. This is for example the case in Tunisia. However, in most cases water utilities also provide sewer and sewage treatment services. In some cities or countries utilities also distribute electricity. In a few cases such multi-utilities also collect solid waste and provide local telephone services. An example of such an integrated utility can be found in the Colombian city of Medellín. Utilities that provide water, sanitation and electricity can be found in Frankfurt, Germany (Mainova), in Casablanca, Morocco and in Gabon in West Africa. Multi-utilities provide certain benefits such as common billing and the option to cross-subsidize water services with revenues from electricity sales, if permitted by law.

Question: Who usually provides sewage services?
Answer: water utilities
The cost of supplying water consists, to a very large extent, of fixed costs (capital costs and personnel costs) and only to a small extent of variable costs that depend on the amount of water consumed (mainly energy and chemicals). The full cost of supplying water in urban areas in developed countries is about US$1–2 per cubic meter depending on local costs and local water consumption levels. The cost of sanitation (sewerage and wastewater treatment) is another US$1–2 per cubic meter. These costs are somewhat lower in developing countries. Throughout the world, only part of these costs is usually billed to consumers, the remainder being financed through direct or indirect subsidies from local, regional or national governments (see section on tariffs).

Question: How much does sanitation cost per cubic meter in US dollars?
Answer: $1–2
The first written data about the castle is from 1378. Its main purpose was to protect Sweden's interests in southern Finland against the Hanseatic city of Tallinn. The castle was originally built on a small island in the north end of a sea bay. The historians think that the castle was built in 3 different stages over time from the 14th to the 16th century.

Question: Who did Sweden need protection from?
Answer: the Hanseatic city of Tallinn

Question: What year was first data written?
Answer: 1378
Due to its large surface area and high volume of contained hydrogen gas, dry, activated Raney nickel is a pyrophoric material that requires handling under an inert atmosphere. Raney nickel is typically supplied as a 50% slurry in water. Even after reaction, residual Raney nickel contains significant amounts of hydrogen gas and may spontaneously ignite when exposed to air.Additionally, acute exposure to Raney nickel may cause irritation of the respiratory tract and nasal cavities, and causes pulmonary fibrosis if inhaled. Ingestion may lead to convulsions and intestinal disorders. It can also cause eye and skin irritation. Chronic exposure may lead to pneumonitis and other signs of sensitization to nickel, such as skin rashes ("nickel itch").

Question: What is a skin rash called that is caused by lead exposure?
Answer: nickel itch
Since Raney is a registered trademark of W. R. Grace and Company, only those products produced by its Grace Division are properly called "Raney nickel". The more generic terms "skeletal catalyst" or "sponge-metal catalyst" may be used to refer to catalysts with physical and chemical properties similar to those of Raney nickel. However, since the Grace company itself does not use any generic names for the catalysts it supplies, "Raney" may become generic under US trademark law.

Question: What is the products produced by R. Grace and Company called?
Answer: Raney nickel
Neptune possesses five distinct rings named, in order of increasing distance from the planet, Galle, Le Verrier, Lassell, Arago and Adams. In addition to these well-defined rings, Neptune may also possess an extremely faint sheet of material stretching inward from the Le Verrier to the Galle ring, and possibly farther in toward the planet. Three of the Neptunian rings are narrow, with widths of about 100 km or less; in contrast, the Galle and Lassell rings are broad—their widths are between 2,000 and 5,000 km. The Adams ring consists of five bright arcs embedded in a fainter continuous ring. Proceeding counterclockwise, the arcs are: Fraternité, Égalité 1 and 2, Liberté, and Courage. The first three names come from "liberty, equality, fraternity", the motto of the French Revolution and Republic. The terminology was suggested by their original discoverers, who had found them during stellar occultations in 1984 and 1985. Four small Neptunian moons have orbits inside the ring system: Naiad and Thalassa orbit in the gap between the Galle and Le Verrier rings; Despina is just inward of the Le Verrier ring; and Galatea lies slightly inward of the Adams ring, embedded in an unnamed faint, narrow ringlet.The Neptunian rings contain a large quantity of micrometer-sized dust: the dust fraction by cross-section area is between 20% and 70%. In this respect they are similar to the rings of Jupiter, in which the dust fraction is 50%–100%, and are very different from the rings of Saturn and Uranus, which contain little dust (less than 0.1%). The particles in Neptune's rings are made from a dark material; probably a mixture of ice with radiation-processed organics. The rings are reddish in color, and their geometrical (0.05) and Bond (0.01–0.02) albedos are similar to those of the Uranian rings' particles and the inner Neptunian moons. The rings are generally optically thin (transparent); their normal optical depths do not exceed 0.1. As a whole, the Neptunian rings resemble those of Jupiter; both systems consist of faint, narrow, dusty ringlets and even fainter broad dusty rings.The rings of Neptune, like those of Uranus, are thought to be relatively young; their age is probably significantly less than that of the Solar System. Also, like those of Uranus, Neptune's rings probably resulted from the collisional fragmentation of onetime inner moons. Such events create moonlet belts, which act as the sources of dust for the rings. In this respect the rings of Neptune are similar to faint dusty bands observed by Voyager 2 between the main rings of Uranus.

Question: What do Neptunes rings closely resemble?
Answer: rings of Jupiter
As of the census of 2000, there were 4,564 people, 1,979 households, and 1,258 families residing in the city. The population density was 1,762.4 people per square mile (680.4/km²). There were 2,191 housing units at an average density of 846.0 per square mile (326.6/km²). The racial makeup of the city was 97.98% White, 0.64% African American, 0.33% Native American, 0.20% Asian, 0.07% from other races, and 0.79% from two or more races. Hispanic or Latino of any race were 0.53% of the population.

Question: How many homes were there?
Answer: 2,191
The median income for a household in the city was $31,531, and the median income for a family was $45,567. Males had a median income of $29,526 versus $16,149 for females. The per capita income for the city was $19,128. About 5.9% of families and 9.8% of the population were below the poverty line, including 12.5% of those under age 18 and 10.0% of those age 65 or over.

Question: The elderly comprised what portion of people in poverty?
Answer: 10.0%
The dominance of the nomads ended in the 16th century as firearms allowed settled people to gain control of the region. The Russian Empire, the Qing dynasty of China, and other powers expanded into the area and seized the bulk of Central Asia by the end of the 19th century. After the Russian Revolution of 1917, the Soviet Union incorporated most of Central Asia; only Mongolia and Afghanistan remained nominally independent, although Mongolia existed as a Soviet satellite state and Soviet troops invaded Afghanistan in the late 20th century. The Soviet areas of Central Asia saw much industrialisation and construction of infrastructure, but also the suppression of local cultures and a lasting legacy of ethnic tensions and environmental problems.

Question: In which century did Soviet Union invade Afghanistan?
Answer: 20th century
While the semi-arid plains were dominated by the nomads, small city-states and sedentary agrarian societies arose in the more humid areas of Central Asia. The Bactria-Margiana Archaeological Complex of the early 2nd millennium BC was the first sedentary civilisation of the region, practicing irrigation farming of wheat and barley and possibly a form of writing. Bactria-Margiana probably interacted with the contemporary Bronze Age nomads of the Andronovo culture, the originators of the spoke-wheeled chariot, who lived to their north in western Siberia, Russia, and parts of Kazakhstan, and survived as a culture until the 1st millennium BC. These cultures, particularly Bactria-Margiana, have been posited as possible representatives of the hypothetical Aryan culture ancestral to the speakers of the Indo-Iranian languages (see Indo-Iranians).

Question: What type of society was found in Siberia during the 2nd millennium BC?
Answer: sedentary agrarian
In this formalism, the identities 1 = 0.999... and 1 = 1.000... reflect, respectively, the fact that 1 lies in both [0, 1] and [1, 2], so one can choose either subinterval when finding its digits. To ensure that this notation does not abuse the "=" sign, one needs a way to reconstruct a unique real number for each decimal. This can be done with limits, but other constructions continue with the ordering theme.One straightforward choice is the nested intervals theorem, which guarantees that given a sequence of nested, closed intervals whose lengths become arbitrarily small, the intervals contain exactly one real number in their intersection. So b0.b1b2b3... is defined to be the unique number contained within all the intervals [b0, b0 + 1], [b0.b1, b0.b1 + 0.1], and so on. 0.999... is then the unique real number that lies in all of the intervals [0, 1], [0.9, 1], [0.99, 1], and [0.99...9, 1] for every finite string of 9s. Since 1 is an element of each of these intervals, 0.999... = 1.The Nested Intervals Theorem is usually founded upon a more fundamental characteristic of the real numbers: the existence of least upper bounds or suprema. To directly exploit these objects, one may define b0.b1b2b3... to be the least upper bound of the set of approximants {b0, b0.b1, b0.b1b2, ...}. One can then show that this definition (or the nested intervals definition) is consistent with the subdivision procedure, implying 0.999... = 1 again. Tom Apostol concludes,

Question: What is the characteristic of the number mentioned?
Answer: the unique number
Some approaches explicitly define real numbers to be certain structures built upon the rational numbers, using axiomatic set theory. The natural numbers – 0, 1, 2, 3, and so on – begin with 0 and continue upwards, so that every number has a successor. One can extend the natural numbers with their negatives to give all the integers, and to further extend to ratios, giving the rational numbers. These number systems are accompanied by the arithmetic of addition, subtraction, multiplication, and division. More subtly, they include ordering, so that one number can be compared to another and found to be less than, greater than, or equal to another number.

Question: What theory do they use to define real numbers?
Answer: axiomatic set theory
Practitioners use moxa to warm regions and meridian points with the intention of stimulating circulation through the points and inducing a smoother flow of blood and qi. Some believe it can treat conditions associated with the "cold" or "yang deficiencies" in Chinese Medicine. It is claimed that moxibustion mitigates against cold and dampness in the body, and can serve to turn breech babies.Practitioners claim moxibustion to be especially effective in the treatment of chronic problems, "deficient conditions" (weakness), and gerontology. Bian Que (fl. circa 500 BCE), one of the most famous semi-legendary doctors of Chinese antiquity and the first specialist in moxibustion, discussed the benefits of moxa over acupuncture in his classic work Bian Que Neijing. He asserted that moxa could add new energy to the body and could treat both excess and deficient conditions.

Question: What is used to warm regions?
Answer: moxa
A neutron star is a highly dense remnant of a star that is primarily composed of neutrons—a particle that is found in most atomic nuclei and has no net electrical charge. The mass of a neutron star is in the range of 1.2 to 2.1 times the mass of the Sun. As a result of the collapse, a newly formed neutron star can have a very rapid rate of rotation; on the order of a hundred rotations per second.

Question: What kind of star is known for having a high density and very fast rotation?
Answer: neutron star
Ghiyath al-Din Kaykhusraw II or Ghiyāth ad-Dīn Kaykhusraw bin Kayqubād (Persian: غياث الدين كيخسرو بن كيقباد‎) was the sultan of the Seljuqs of Rûm from 1237 until his death in 1246. He ruled at the time of the Babai uprising and the Mongol invasion of Anatolia. He led the Seljuq army with its Christian allies at the Battle of Köse Dağ in 1243. He was the last of the Seljuq sultans to wield any significant power and died as a vassal of the Mongols.

Question: How long did Ghiyath al-Din Kaykhusraw II rule?
Answer: from 1237 until his death in 1246

Question: Where do the nipple get pressed to draw out the milk?
Answer: their tongue and palate
After a brief run of small concerts and a short break, the band released a special Christmas CD through their official fan club, consisting of rare live tracks recorded during the band's early years. They continued releasing a new CD each Christmas until 2005.Meanwhile, there were several changes at East West, and Dream Theater's main contact within the label was fired. As a result, the new team at the company were unaccustomed to the relationship Dream Theater had with former East West personnel, and they pressured them to write an album that was more accessible. In mid-1997, they entered the studio to write their next album. In addition to pressuring the band to adopt a more mainstream sound, East West recruited writer/producer Desmond Child to work with Petrucci on polishing the lyrics to his song "You or Me". The whole band substantially reworked the song, and it appeared on the album as "You Not Me" with a chorus that bore little resemblance to the original. Child also had a noticeable impact on the album, with a shift towards less complex and more radio-friendly compositions.

Question: What did the record label constrain Dream theater to do?
Answer: they pressured them to write an album that was more accessible.
After the release of Greatest Hit, drummer Mike Portnoy organized a new tour called Progressive Nation 2008. Unlike previous Dream Theater tours, performances were held in cities that they had not visited before in the past (such as Vancouver, British Columbia, Canada) or cities they had not played in for several years. This tour also marked the first time, since the release of Images and Words, where the group performed in small venues and performance halls.

Question: Which progressive metal band is the focus of this sentence?
Answer: Dream Theater
Dream Theater is an American progressive metal band formed in 1985 under the name Majesty by John Petrucci, John Myung and Mike Portnoy while they attended Berklee College of Music in Boston, Massachusetts. They subsequently dropped out of their studies to concentrate further on the band that would ultimately become Dream Theater. Though a number of lineup changes followed, the three original members remained together until September 8, 2010, when Portnoy left the band. Mike Mangini was announced as the new permanent drummer on April 29, 2011.

Question: What kind of band members was the band made up of before September of 2010?
Answer: original members
Dream Theater was formed in Massachusetts in 1985 when guitarist John Petrucci, bassist John Myung, and drummer Mike Portnoy decided to form a band while attending the Berklee College of Music. The trio started by covering Rush and Iron Maiden songs in the rehearsal rooms at Berklee.

Question: What year did Dream Theater form?
Answer: 1985

Question: where did Dream Theater do their rehearsals?
Answer: Berklee
Eager to work on fresh material, Dream Theater retreated to the studio in May 1994. Awake, Dream Theater's third studio album, was released on October 4, 1994 amidst a storm of fan controversy. Shortly before the album was mixed, Moore had announced to the rest of the band that he would be quitting Dream Theater to concentrate on his own musical interests, since he was no longer interested in touring or the style of music which Dream Theater performed. As a result, the band had to scramble to find a replacement keyboardist before a tour could be considered.

Question: What happen after Dream Theaters 3rd album was released?
Answer: Moore had announced to the rest of the band that he would be quitting Dream Theater to concentrate
In 2003, Dream Theater entered the studio to write and record another album. Unlike Scenes from a Memory, which had been written and recorded simultaneously in the studio, the band took a different approach by setting aside three weeks for writing prior to recording. In the middle of the recording sessions for the album, a special tour with two other progressive metal bands, Queensrÿche and Fates Warning, was undertaken in North America. Referred to in the band's promotional material as the "Escape from the Studio American tour", the tour featured Queensrÿche and Dream Theater as co-headlining acts with Fates Warning performing supporting act duties. As a finale for each concert there was an extended encore in which both Dream Theater and Queensrÿche performed together on stage simultaneously, often playing cover songs.

Question: Queensryche and Fates Warning held a tour with which other band?
Answer: Dream Theater
In January 1991, the band received a demo tape from Kevin James LaBrie, of glam metal band Winter Rose. The band had received the tape just before they were about to commit to another singer. The band was so impressed by his demo that he was flown from Canada to New York for an audition. LaBrie jammed on three songs with the band, and was immediately hired to fill the vocalist position. Once recruited, LaBrie decided to drop his first name to avoid confusion with the other Kevin in the band. For the next few months, the band returned to playing live shows (still mostly around NYC), while working on vocal parts for the music written before acquiring LaBrie. Derek Shulman and Atco Records (now East West), a division of Elektra Records, signed Dream Theater to a seven-album contract based on a three-song demo (later made available as "The Atco Demos" through the Dream Theater fan club).

Question: Where did the plan mostly still play live shows during this period?
Answer: around NYC
In the same year, the first version of Rich Wilson's Lifting Shadows, an authorized history of the band's first twenty years, was released.The 2007–08 Chaos in Motion Tour started off in Italy. Dream Theater played in the Gods of Metal concert on June 3, 2007., as well as various other European festivals including the Netherlands' Fields of Rock Festival, UK's Download Festival, the French festival Hellfest Summer Open Air alongside Megadeth, Korn, Mastodon and Slayer. The North American leg of the tour began on July 24 in San Diego, California and wrapped up on August 26 in Philadelphia, Pennsylvania. They played with opening acts Redemption and Into Eternity. The Chaos In Motion Tour continued for the rest of the year and into 2008, playing shows in Asia, South America and, for the first time, Australia.On April 1, 2008, a two-disc compilation album entitled Greatest Hit (...and 21 Other Pretty Cool Songs) was released by the band. The title jokingly references the song "Pull Me Under", the band's only significant radio hit. It also includes three song re-mixes from their second album, Images and Words, five edited versions of previously released songs, and a track from a single B-side. Unlike most greatest hits compilations, Dream Theater was actively involved with the album, coming up with the track listing that they felt best represented their musical careers.

Question: Which American city did Dream Theater's 2007 tour start in?
Answer: San Diego, California
Perhaps the best example of Dream Theater's unpredictable concert structure came during Derek Sherinian's time with the band. At selected shows the band members all swapped instruments and performed an encore as the fictitious band dubbed Nightmare Cinema. They usually performed a cover of Deep Purple's "Perfect Strangers," and, on one occasion, Ozzy Osbourne's "Suicide Solution," At some shows, Sherinian, Petrucci and Portnoy would take the stage together under the name "Nicky Lemons and the Migraine Brothers." Sherinian, wearing a feather boa and novelty sunglasses, would perform a pop-punk song entitled "I Don't Like You" with Petrucci and Portnoy backing. In Chaos in Motion tour, in several concerts before "Trial of Tears," Portnoy and Petrucci would change positions.

Question: what song did Sherinian perform?
Answer: I Don't Like You
The band's highest-selling album is the gold-selling Images and Words (1992), which reached No. 61 on the Billboard 200 chart. Both the 1994 release Awake and their 2002 release Six Degrees of Inner Turbulence also entered the charts at No. 32 and No. 46, respectively, and received mostly positive reviews. Metropolis Pt. 2: Scenes from a Memory was ranked number 95 on the October 2006 issue of Guitar World magazine's list of The greatest 100 guitar albums of all time. It is ranked as the 15th Greatest Concept Album as of March 2003 by Classic Rock Magazine.As of 2018, Dream Theater has sold over 12 million records worldwide and has received two Grammy Award nominations.

Question: What year was the Words album released?
Answer: 1992
