PROBLEM: Context_1 : Kepler-37 is a G-type main-sequence star located in the constellation Lyra 215.2 light years from Earth. It is host to exoplanets Kepler-37b, Kepler-37c, Kepler-37d and Kepler-37e, all of which orbit very close to it. Kepler-37 has a mass about 80.3 percent of the Sun's and a radius about 77 percent as large. It has a temperature similar to that of the Sun, but a bit cooler at 5,417 K. It has about half the metallicity of our Sun. With an age of roughly 6 billion years, it is slightly older than the Sun, but is still a main-sequence star. Until January 2015, Kepler-37 was the smallest star to be measured via asteroseismology. Context_2 : A blue straggler is a main-sequence star in an open or globular cluster that is more luminous and bluer than stars at the main-sequence turn-off point for the cluster. Blue stragglers were first discovered by Allan Sandage in 1953 while performing photometry of the stars in the globular cluster M3. Standard theories of stellar evolution hold that the position of a star on the Hertzsprung–Russell diagram should be determined almost entirely by the initial mass of the star and its age. In a cluster, stars all formed at approximately the same time, and thus in an H–R diagram for a cluster, all stars should lie along a clearly defined curve set by the age of the cluster, with the positions of individual stars on that curve determined solely by their initial mass. With masses two to three times that of the rest of the main-sequence cluster stars, blue stragglers seem to be exceptions to this rule. The resolution of this problem is likely related to interactions between two or more stars in the dense confines of the clusters in which blue stragglers are found. Context_3 : A G-type main-sequence star (Spectral type: G-V), often (and imprecisely) called a yellow dwarf, or G dwarf star, is a main-sequence star (luminosity class V) of spectral type G. Such a star has about 0.84 to 1.15 solar masses and surface temperature of between 5,300 and 6,000 K. Like other main-sequence stars, a G-type main-sequence star is converting the element hydrogen to helium in its core by means of nuclear fusion. The Sun, the star to which the Earth is gravitationally bound in the Solar System and the object with the largest apparent magnitude, is an example of a G-type main-sequence star. Each second, the Sun fuses approximately 600 million tons of hydrogen to helium, converting about 4 million tons of matter to energy. Besides the Sun, other well-known examples of G-type main-sequence stars include Alpha Centauri A, Tau Ceti, and 51 Pegasi. Context_4 : Hereford Arizona Observatory (HAO), IAU-code G95, is an astronomical observatory, owned and operated by amateur astronomer Bruce L. Gary. Gary is the author of many publications related to astronomy, including "Exoplanet Observing for Amateurs" (2008), currently available in a second edition (2009). Observational studies of unusual starlight fluctuations in KIC 8462852 and WD 1145+017 are recent interests. Context_5 : 74 Cygni is a star in the constellation Cygnus. Its apparent magnitude is 5.05. Located around 65.83 pc distant, it is a blue-white main-sequence star of spectral type A5V, a star that is fusing its core hydrogen. Context_6 : GD 61 is a white dwarf with a planetary system located 150 light-years from Earth in the constellation Perseus. It is thought to have been a main-sequence star of spectral type A0V with around three times the mass of the Sun that has aged and passed through a red-giant phase, leaving a dense, hot remnant that has around 70% of the Sun's mass and a surface temperature of 17,280 K. It is thought to be around 600 million years old, including both its life as a main-sequence star and as a white dwarf. It has an apparent magnitude of 14.8. GD 61 was first noted as a potential degenerate star in 1965, in a survey of white-dwarf suspects by astronomers from the Lowell Observatory in Arizona. Context_7 : KIC 8462852 (also Tabby's Star or Boyajian's Star) is an F-type main-sequence star located in the constellation Cygnus approximately 1280 ly from Earth. Unusual light fluctuations of the star, including up to a 22% dimming in brightness, were discovered by citizen scientists as part of the Planet Hunters project, and, in September 2015, astronomers and citizen scientists associated with the project posted a preprint of an article describing the data and possible interpretations. The discovery was made from data collected by the "Kepler" space telescope, which observes changes in the brightness of distant stars to detect exoplanets. Context_8 : K-type main-sequence stars may be candidates for supporting extraterrestrial life. These stars are known as "Goldilocks stars" as they emit enough radiation in the non-UV ray spectrum to provide a temperature that allows liquid water to exist on the surface of a planet; they also remain stable in the main phase longer than the Sun, allowing more time for life to form on a planet around a K-type main-sequence star. The planet's habitable zone, ranging from 0.1–0.4 to 0.3–1.3 astronomical units (AU), depending on the size of the star, is often far enough from the star so as not to be tidally locked to the star, and to have a sufficiently low solar flare activity not to be lethal to life. In comparison, red dwarf stars have too much solar activity and quickly tidally lock the planets in their habitable zones, making them less suitable for life. The odds of intelligent life arising may be better on planets around K-type main-sequence stars than around Sun-like stars, given the extra time available for it to evolve. Few planets thus far have been found around K-type main-sequence stars, but those that have are potential candidates for extraterrestrial life. Context_9 : Iota Cygni (ι Cyg, often simply called ι Cyg) is a star in the constellation Cygnus. Its apparent magnitude is 3.77 Located around 37.20 pc distant, it is a blue-white main-sequence star of spectral type A5V, a star that is currently fusing its core hydrogen. Based on rapid changes in the strength of a singly-ionized calcium absorption line, the star is likely host to a circumstellar disk. Context_10 : An F-type main-sequence star (F V) is a main-sequence, hydrogen-fusing star of spectral type F and luminosity class V. These stars have from 1.0 to 1.4 times the mass of the Sun and surface temperatures between 6,000 and 7,600 K. This temperature range gives the F-type stars a yellow-white hue. Because a main-sequence star is referred to as a dwarf star, this class of star may also be termed a yellow-white dwarf. Famous examples include Procyon A, Gamma Virginis A and B, and KIC 8462852. fact_1 :  Observational studies of unusual starlight fluctuations in KIC 8462852 and WD 1145+017 are recent interests. fact_2 : KIC 8462852 (also Tabby's Star or Boyajian's Star) is an F-type main-sequence star located in the constellation Cygnus approximately 1280 ly from Earth. Answer: F-type

SOLUTION: Hereford Arizona Observatory found fluctuations in what type of mainsequence star in Cygnus?

PROBLEM: Context_1 : Loudon Snowden Wainwright III (born September 5, 1946) is an American songwriter, folk singer, humorist, and actor. He is the father of musicians Rufus Wainwright, Martha Wainwright, and Lucy Wainwright Roche; brother of Sloan Wainwright; and former husband of the late folksinger Kate McGarrigle. He resides in Canada. Context_2 : Album III, as its title indicates, is the third full album from Loudon Wainwright III. It was originally released in 1972 on Columbia Records. "Album III" would spawn Loudon Wainwright's most popular hit single, "Dead Skunk", one of the many 'novelty songs' sprinkled throughout Wainwright's career. Although Wainwright has maintained an ironic, sometimes sepulchral sense of humor, "Dead Skunk", despite its commercial success, has dogged him ever since, as he comments on 1985's album "I'm Alright", "Were you embarrassed about 'Dead Skunk'"? Context_3 : History is the twelfth studio album by American singer-songwriter Loudon Wainwright III, released on September 21, 1992 on Charisma Records. The album was recorded following the death of Wainwright's father, Loudon Wainwright Jr.. Regarding his father's death and its influence on "History", Wainwright stated that: Context_4 : Lucy is the debut studio album by American folk musician Lucy Wainwright Roche, released on October 26, 2010 on Strike Back Records. Produced by Stewart Lerman, the album features appearances from Roche's father Loudon Wainwright III, The Roches, Steuart Smith, David Mansfield and Kelly Hogan. Context_5 : Loudon Snowden Wainwright Jr. (December 16, 1924 – December 12, 1988) was an American writer. He was the father of folk singer Loudon Wainwright III and singer Sloan Wainwright, and grandfather to Rufus Wainwright, Martha Wainwright, and Lucy Wainwright Roche. Context_6 : Martha Wainwright (born May 8, 1976) is a Canadian-American folk-rock singer-songwriter. She is the daughter of American folk singer and actor Loudon Wainwright III and Canadian folk singer-songwriter Kate McGarrigle. She was raised in a musical family along with her older brother, Rufus Wainwright, in Montreal, Quebec, Canada. Context_7 : Sloan Wainwright (born 1957) is an artist and member of the American independent music scene. Her musical style consists of a combination of folk, rock, jazz, and blues, an approach which owes itself to her time writing and performing throughout Greenwich Village. Context_8 : Recovery is the nineteenth studio album by American singer-songwriter Loudon Wainwright III, released on August 19, 2008 on Yep Roc Records. The songs are "re-covers" from his first four albums: "Loudon Wainwright III" (1970), "Album II" (1971), "Album III" (1972) and "Attempted Mustache" (1973). Context_9 : Songs in the Dark is the debut album by the Wainwright Sisters, a singer-songwriter duo featuring the Canadian-American Martha Wainwright and her American half-sister Lucy Wainwright Roche. The album, released on November 13, 2015, includes lullabies that their mothers Kate McGarrigle and Suzzy Roche sang to them as children, plus songs by Woody Guthrie, Jimmie Rogers, and their father Loudon Wainwright III. Context_10 : Loudon Wainwright III (also known as Album I) is the debut album of Loudon Wainwright III. It was released on vinyl in 1970 on Atlantic Records. Like his second effort "Album II", the album is a solo acoustic effort. Though his ironic sense of humour is evident, this is an altogether bleaker and more acerbic album ("Black Uncle Remus", "Four is a Magic Number", "Glad To See You've Got Religion") than most of his 1970s work. fact_1 :  He is the father of musicians Rufus Wainwright, Martha Wainwright, and Lucy Wainwright Roche; brother of Sloan Wainwright; and former husband of the late folksinger Kate McGarrigle. fact_2 : Sloan Wainwright (born 1957) is an artist and member of the American independent music scene. fact_3 :  Her musical style consists of a combination of folk, rock, jazz, and blues, an approach which owes itself to her time writing and performing throughout Greenwich Village. Answer: Sloan Wainwright

SOLUTION: Loudon Wainwright III is related to which American independent folk singer?

PROBLEM: Context_1 : Ulmus crassifolia , the Texas cedar elm or simply cedar elm, is a deciduous tree native to south central North America, mainly in southern and eastern Texas, southern Oklahoma, Arkansas and Louisiana, with small populations in western Mississippi, southwest Tennessee and north central Florida; it also occurs in northeastern Mexico. It is the most common elm tree in Texas. The tree typically grows well in flat valley bottom areas referred to as 'Cedar Elm Flats'. The common name 'cedar elm' is derived from the trees' association with juniper trees, locally known as cedars. Context_2 : Multistriatin is a pheromone of the elm bark beetle. It is a volatile compound released by a virgin female beetle when she has found a good source of food, such as an elm tree. Context_3 : Bengbu () is a mid-sized city in northern Anhui Province, China. Its built-up ("or metro") area made of 4 urban districts has nearly one million residents, though the Prefecture-level city under its jurisdiction had 3,164,467 registered residents at the 2010 census. Its name means "Oyster Wharf" in Chinese, echoing its former reputation as a freshwater pearl fishery. Context_4 : Tree House, also known as The Tree, is a mediaeval timber-framed house on the High Street in Crawley, a town and borough in West Sussex, England. It is the original manor house of Crawley, and was built in the early 15th century and rebuilt in the mid-16th century. It now has a modern exterior and is disused, but the old structure is still in place inside. Situated in a prominent position facing both the High Street and The Boulevard, two of Crawley town centre's main roads, its name commemorates an ancient elm tree which stood outside for hundreds of years and was one of Crawley's landmarks. Context_5 : Ptelea is a genus of flowering plants in the citrus family, Rutaceae. The name, of Greek derivation, is the classical name of the elm tree. Carl Linnaeus used that word for this genus because of the resemblance of its fruit to that of the elm. Members of the genus are commonly known as hoptrees. Context_6 : Elm Tree Farm is a suburb of the market town of Stockton-on-Tees within the borough of Stockton-on-Tees and ceremonial county of County Durham, in North East England. Whitehouse Primary School is in Elm Tree Farm. It is situated to the north-west of the town centre, around the post code TS19. Around the area of Elm Tree Avenue and the Elm Tree Pub it boasts its own community centre, along with Fairfield Social Club which can be confusing, as Elm Tree Social Club is actually in Fairfield. Context_7 : Yushu () is a county-level city under the jurisdiction of Changchun, the capital of Jilin province, People's Republic of China. It is more than 140 km to the northeast of central Changchun, and around 100 km south of Harbin. The name of the place means "Elm Tree". The northernmost county-level division of Changchun, it borders Dehui to the southwest as well as the prefecture-level division of Harbin (Heilongjiang) to the northeast. Context_8 : Richneck Plantation Site is a historic archaeological site located at Newport News, Virginia. It is the site of the 17th century home of Miles Cary, Jr., Clerk of Court for many years and four succeeding generations of Carys who also held that office. According to tradition, the county court in its early years was held beneath a giant hackberry tree (of the elm tree family) on this site. The home survived until 1865. The ancient tree, whose symbol appears on the City seal, died. It was replaced and stands today with the grave sites of several family members beneath it. Context_9 : Tulliallan is a new residential community alongside the suburb of Berwick at 1/805 Berwick Cranbourne Road, Cranbourne North. The community is named after the heritage-listed ‘Tulliallan’ consisting of a stone brick "Shearers Cottage" constructed circa 1860 and an "Avenue of Elms", one of the largest private ones in the municipality. These Elm Trees are estimated to be 117 years old and have been generously donated by Tulliallan’s former owner Peter White and will border the future Elm Tree Gardens community parkland. Context_10 : The Liberty Tree (1646–1775) was a famous elm tree that stood in Boston near Boston Common, in the years before the American Revolution. In 1765, colonists in Boston staged the first act of defiance against the British government at the tree. The tree became a rallying point for the growing resistance to the rule of Britain over the American colonies, and the ground surrounding it became known as Liberty Hall. The Liberty Tree was felled by British troops and Loyalists in 1775. fact_1 : Yushu () is a county-level city under the jurisdiction of Changchun, the capital of Jilin province, People's Republic of China. fact_2 :  The name of the place means "Elm Tree". fact_3 :  Its name means "Oyster Wharf" in Chinese, echoing its former reputation as a freshwater pearl fishery. Answer: Yushu
