Example Input: Context_1 : The Luray Norfolk and Western Passenger Station is a historic train station located in Luray, Virginia, United States. The Shenandoah Valley Railroad reached Luray in 1881 and constructed a station near where the present station is located. Shortly after the Norfolk and Western Railway absorbed the Shenandoah Valley Railroad in 1890, plans arose to construct a new station in Luray. This station, which still stands, was constructed in 1906 and was designed by the railroad's Chief Engineer, Charles S. Churchill. The structure was partially destroyed by fire in 1908 when it was struck by lightning; however, it was soon thereafter reconstructed according to the original design. The station is a one-story brick structure featuring a hip roof. The building was converted to freight use around 1960 and was sold to the town of Luray by the Norfolk and Western's successor, the Norfolk Southern Railway, in 1999. Context_2 : The Conococheague Mountain Tunnel was a proposed railroad tunnel in Perry County, Pennsylvania. It was originally planned as part of the Path Valley Railroad, with the intent to link the Newport and Shermans Valley Railroad with the East Broad Top Railroad and the Tuscarora Valley Railroad further west. Only about 100 feet of either end of the planned 2600 foot tunnel was completed in 1894. Context_3 : The Lehigh and Mahanoy Railroad, originally the Quakake Railroad (pronounced quake-ache), was an independently financed railroad planned and built at almost the same time as the Lehigh Valley Railroad (LVRR), when in part, some of its backers were also of the backers (and perhaps officers) of the Lehigh Valley Railroad. The railroad is mentioned as part of the engineering report following the survey of 1846 by Robert H. Sayre, at the time chief engineer of the Lehigh Coal & Navigation Company, where the branch is "described as part of the overall scheme to connect New York Harbor via the Central Railroad of New Jersey to the frontiers via Lake Erie and the Susquehanna River valley. The official incorporated name on the report is the Delaware, Lehigh, Schuylkill, & Susquehanna Railroad Co. where the Schuylkill name is the Quakake Creek climb out of the Lehigh Valley and drop down into Delano Junction which has a descent path to Tamaqua, Pennsylvania in the Little Schuylkill River basin. Accordingly, the Quakake Railroad would become part of the Mahanoy Branch of the Lehigh Valley Railroad in northeastern to north-central Pennsylvania. The Catawissa region was an important source of iron ores and developed into an Anthracite pig iron smelting center, as did Catasauqua, Pennsylvania also on the line of the Lehigh Valley. Context_4 : Shenandoah Valley Railroad was a line completed on June 19, 1882, extending down the Shenandoah Valley from Hagerstown, Maryland through the West Virginia panhandle into Virginia to reach Roanoke, Virginia and to connect with the Norfolk and Western Railway (N&W). The development of this railroad had considerable backing from the Pennsylvania Railroad. In September 1890 it went into bankruptcy and was reorganized as the Shenandoah Valley Railway. In December 1890, it became part of N&W. Today the tracks are a major artery of the Norfolk Southern system. Context_5 : The Shenandoah Valley Railroad (reporting mark SV) is a shortline railroad operating 20.2 miles of track between Staunton and Pleasant Valley, Virginia. The railroad interchanges with CSX and Buckingham Branch in Staunton and Norfolk Southern in Pleasant Valley. The railroad was purchased from Norfolk Southern in 1993 and is currently operated by the Durbin and Greenbrier Valley Railroad. Context_6 : The Belvidere Delaware Railroad (Bel Del, 1851–1871) was a railroad running along the eastern shore of the Delaware River from Trenton, New Jersey north via Phillipsburg, New Jersey to the small village of Manunka Chunk, New Jersey. It became an important feeder line for the Lehigh Valley Railroad's join to the Central Railroad of New Jersey, which was constructed into Phillipsburg, NJ at about the same time. This connected Philadelphia and Trenton, NJ at one end of the shortline railroad to the rapidly growing lower Wyoming Valley region, and via the Morris Canal or the CNJ, a slow or fast connection to New York City ferries crossing New York Harbor from Jersey City, NJ. In 1871 the CNJ leased various railroads in Pennsylvania, most from the Lehigh Coal & Navigation Company allowing the CNJ to penetrate to the upper Wyoming Valley, over some stretches, competing directly with the Lehigh Valley Railroad and with the Lehigh Canal and the trunk road connection of the Belvidere Delaware Railroad to New York became less profitable since Philadelphia connected more easily to Northeastern Pennsylvania thereafter without needing a double-crossing of the Delaware River; a general revenue decline ensued, leading to the Pennsylvania Railroad acquiring the rights, where it served as part of the Pennsylvania Railroad (PRR) system, carrying mainly anthracite coal and iron ore from northeastern Pennsylvania to population centers along the coast. Context_7 : The Cumberland Valley Railroad (reporting mark CVRR) was an early railroad in Pennsylvania, United States, originally chartered in 1831 to connect with Pennsylvania's Main Line of Public Works. Freight and passenger service in the Cumberland Valley in south central Pennsylvania from near Harrisburg to Chambersburg began in 1837, with service later extended to Hagerstown, Maryland and then extending into the Shenandoah Valley to Winchester, Virginia. It employed up to 1,800 workers. Context_8 : Canadian Pacific Railway No. 1246 was one of three 1200-series Canadian Pacific Railway locomotives in the Steamtown, USA collection. Like CP 1293 and CP 1278, this locomotive was one the operational engines at Steamtown. When Steamtown left its Bellows Falls, Vermont location in the fall of 1983, the engine led the "farewell to Vermont" excursions. There were two such 100 mi excursions "through a landscape of covered bridges, rushing streams and scenic countryside". The train had the capacity of 800–1000 passengers. Built in 1946, CPR 1246 is a 4-6-2 type, class G5c locomotive. After operating in Steamtown in Scranton between 1984–1986, it was determined that 1246 was inadequate for service as it was "too light for the heavy grades and sharp curves of the Steamtown line". The National Park Service sold it to the|Connecticut Valley Railroad]], in 1988. Note The locomotive was never owned by the Valley Railroad of Essex.Ct. The Railroad Museum of New England,changed their name from The Connecticut Valley Railroad sometime after they moved to Thonaston, Ct. The engine was moved to the Connecticut Valley Railroad This locomotive was on static display from 1996–2008, at the Valley Railroad in Essex, Connecticut. In 2008, it was moved to the Naugatuck Railroad which is operated by the Railroad Museum of New England, Thomaston, Connecticut. Context_9 : The Pennsylvania Railroad (reporting mark PRR) (or Pennsylvania Railroad Company and also known the "Pennsy") was an American Class I railroad that was established in 1846 and was headquartered in Philadelphia, Pennsylvania. It was called the Pennsylvania Railroad because it was established in the state of Pennsylvania. Context_10 : The Durbin and Greenbrier Valley Railroad (reporting mark DGVR) is a heritage and freight railroad in the U.S. states of Virginia and West Virginia. It operates the West Virginia State Rail Authority-owned Durbin Railroad and West Virginia Central Railroad (reporting mark WVC) , as well as the Shenandoah Valley Railroad in Virginia. Beginning in 2015, DGVR began operating the historic geared steam-powered Cass Scenic Railroad, which was previously operated by the West Virginia Division of Natural Resources as part of Cass Scenic Railroad State Park. fact_1 :  The development of this railroad had considerable backing from the Pennsylvania Railroad. fact_2 : The Pennsylvania Railroad (reporting mark PRR) (or Pennsylvania Railroad Company and also known the "Pennsy") was an American Class I railroad that was established in 1846 and was headquartered in Philadelphia, Pennsylvania. Answer: "Pennsy"
Example Output: The Shenandoah Valley Railroad had considerably backing from another railroad with what nickname?

Example Input: 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
Example Output: Hereford Arizona Observatory found fluctuations in what type of mainsequence star in Cygnus?

Example Input: Context_1 : Sick is the second studio album by American rock band Loaded. It is their first album since reforming after they went on hiatus in 2002. It was recorded and produced by Martin Feveyear at Jupiter Studios in Seattle, Washington, and was released on March 30, 2009 in Europe and April 7 in the US, through Century Media Records. Writing for the album began in 2008 when vocalist Scott Weiland departed Duff McKagan's other band, Velvet Revolver, in April of the same year. Recording for the follow-up to their 2001 debut album "Dark Days" began and was completed in June 2008. Context_2 : Stone Temple Pilots is the sixth studio album by American rock band Stone Temple Pilots. The album was released worldwide from May 21 through May 27, 2010, and is the band's first album since 2001's "Shangri-La Dee Da". The album is the result of the band's reunion, which occurred in April 2008 with their North American tour. After Stone Temple Pilots had begun playing together, the band decided to record again, but a lawsuit filed by Atlantic Records on June 12, 2008, made the sixth album an uncertainty. Atlantic eventually withdrew the lawsuit, and the band's attorney called the legal situation a "misunderstanding". This is the last album to feature vocalist Scott Weiland before he was fired from the band in 2013 and died in 2015. Context_3 : Art of Anarchy is an American hard rock supergroup formed in 2011. The band features twin brothers Jon and Vince Votta on guitar and drums, current Disturbed bassist John Moyer, former Guns N' Roses guitarist Ron "Bumblefoot" Thal as co-guitarist and producer, and, as of 2016, Creed vocalist Scott Stapp. The band's first album features the late former Stone Temple Pilots and Velvet Revolver vocalist Scott Weiland on vocals. Context_4 : "Hollywood Bitch" is a song by the American rock band Stone Temple Pilots. It is the second & final single from the group's fifth studio album, "Shangri-La Dee Da". The song was written by vocalist Scott Weiland and bassist Robert DeLeo. During live performances of the song in concert, Robert's brother and guitarist Dean DeLeo performs the backing vocals. Context_5 : "Vasoline" is a song by American rock band Stone Temple Pilots from their second album, "Purple". The song was the second single of the album (and also the second most successful, only behind "Interstate Love Song"), reaching #1 on the "Billboard" Mainstream Rock Tracks chart for two weeks. The song's odd-sounding intro was created by Robert DeLeo, who ran his bass through a wah-wah pedal to get the said effect. The song's lyrics were written by vocalist Scott Weiland. "Vasoline" also appears on the greatest hits compilation album "Thank You". A live version also appears on The Family Values 2001 Tour compilation. Context_6 : "Unglued" is a 1994 promo single from Stone Temple Pilots' second album "Purple". It was performed live on the "Late Show with David Letterman" in December 1994. STP had appeared on Letterman twice before, to perform their songs "Wicked Garden" and "Vasoline", and would appear four more times. The song, like "Vasoline", is known for its highly distorted guitar intro and prominent bass. "Unglued" was only a minor hit for the band, but can still be heard on radio stations in the United States and remains a staple in their live shows. This is the last song Scott Weiland performed before he died. Context_7 : The Madness is the second studio album by American rock band Art of Anarchy, released on March 24, 2017. It is the first album to feature former Creed vocalist Scott Stapp since the passing of former member Scott Weiland in 2015. According to website Loudwire.com, the band is "taking a new direction" with their music on the album. Context_8 : "Come On, Come In" is a song by American hard rock band Velvet Revolver, featured on the soundtrack to the 2005 superhero film "Fantastic Four". When released as a promotional single in the United States on June 21, 2005, the song reached number 14 on the American "Billboard" Hot Mainstream Rock Tracks chart. The lyrics were written by vocalist Scott Weiland and the music was written by Weiland and the rest of the band; the song was produced by the band, Douglas Grean and Nick Raskulinecz. The music video for "Come On, Come In" was directed by Wayne Isham. Context_9 : "Happy" in Galoshes is the second solo album by American rock singer Scott Weiland. Weiland, known for his roles as the lead singer in Stone Temple Pilots and Velvet Revolver, released his first album, "12 Bar Blues" in 1998. Ten years later, ""Happy" in Galoshes" served as the official follow-up. Two versions have been released, a single disc and double disc deluxe version—the deluxe edition offers a second disc of 10 extra tracks. The album was released November 25, 2008 on Weiland's own Softdrive Records. Produced by Doug Grean and Scott Weiland, with select tracks recorded by Steve Albini, the album features guest appearances by Paul Oakenfold and No Doubt members Adrian Young, Tony Kanal, and Tom Dumont. Oakenfold appears on a cover of David Bowie's "Fame." Weiland has cited Bowie as one of his main influences. Context_10 : Scott Richard Weiland ( ; born Scott Richard Kline; October 27, 1967 – December 3, 2015) was an American musician, singer and songwriter. During a career spanning three decades, Weiland was best known as the lead singer of the band Stone Temple Pilots from 1989 to 2002 and 2008 to 2013. He was also a member of supergroup Velvet Revolver from 2003 to 2008 and recorded one album with another supergroup, Art of Anarchy. He established himself as a solo artist as well, releasing three studio albums, two cover albums, and collaborations with several other musicians throughout his career. fact_1 : "Vasoline" is a song by American rock band Stone Temple Pilots from their second album, "Purple". fact_2 : Scott Richard Weiland ( ; born Scott Richard Kline; October 27, 1967 – December 3, 2015) was an American musician, singer and songwriter. Answer: Stone Temple Pilots
Example Output:
Vasoline is a song by which American rock band, from their second album, the songs lyrics were written by vocalist Scott Weiland?
