Question: What was the age of the oldest member (besides Stephanie) of the group representing Armenia in the Eurovision Song Contest 2015? Passage 1:Chemokine receptors are G protein-coupled receptors containing 7 transmembrane domains that are found predominantly on the surface of leukocytes, making it one of the rhodopsin-like receptors. Approximately 19 different chemokine receptors have been characterized to date, which share many common structural features; they are composed of about 350 amino acids that are divided into a short and acidic N-terminal end, seven helical transmembrane domains with three intracellular and three extracellular hydrophilic loops, and an intracellular C-terminus containing serine and threonine residues that act as phosphorylation sites during receptor regulation. The first two extracellular loops of chemokine receptors are linked together by disulfide bonding between two conserved cysteine residues. The N-terminal end of a chemokine receptor binds to chemokine(s) and is important for ligand specificity. G-proteins couple to the C-terminal end, which is important for receptor signaling following ligand binding. Although chemokine receptors share high amino acid identity in their primary sequences, they typically bind a limited number of ligands. Chemokine receptors are redundant in their function as more than one chemokine is able to bind to a single receptor.
 Passage 2:A return to the Formula Three Euroseries beckoned for van Dam, with a 2009 campaign for Kolles & Heinz Union, the new team set up by Colin Kolles and Werner Heinz. However, the partnership was not to last, as after the rounds at Lausitz, van Dam parted company with the team. In four races, his best finish was eighteenth during the season-opening race at Hockenheim. Van Dam drove in the 24-hour endurance races at the Nürburgring and at Spa, before agreeing to drive the car of PSV Eindhoven in the Superleague Formula series. He replaced Dominick Muermans in the car, with the team lying eighteenth in the overall standings. However, he returned to the Euroseries, for the Barcelona rounds, rejoining his former team SG Formula.
 Passage 3:In February 2015 she was announced as a member of the music group Genealogy (made up of singers from Armenia and the Armenian diaspora) that represented Armenia in the Eurovision Song Contest 2015. Stephanie Topalian represents the Asian continent in the formation whereas the Ethiopian Vahe Tilbian represents Africa, the American Tamar Kaprelian the American continent, the French Essaï Altounian the European continent and the Australian Mary-Jean O'Doherty Basmadjian Oceania and Inga Arshakyan Armenia. The super group sang "Face the Shadow", the Armenian entry to the 2015 Eurovision Song Contest in Vienna, Austria. She became an Armenian citizen along with the other foreign members of Genealogy on 28 April 2015 after being given Armenian passports by President Serzh Sargsyan.

Question: In what year was the Hank Williams song that helped The Midnight Ghost Train get their name released? Passage 1:The Midnight Ghost Train was originally formed by Steve Moss in Buffalo, NY. The band's name comes partially from a Hank William's song lyric in I'm So Lonesome I Could Cry. TMGT's first release was "Johnny Boy EP" in 2008, and in 2009 they self-released their first full length album which was self-titled. The album was self-recorded in their home studio after the band relocated to Kansas. They followed up with their 2012 album "Buffalo", released on Karate Body Records. It was recorded entirely analog by Dave Barbe in Athens, Georgia. Displaying the band's delta blues influences, the album features a Lead Belly cover of Cotton Fields done a cappella. In 2013, TMGT performed at the Roadburn Festival in Tilburg, Netherlands, and released "Live at Roadburn 2013" shortly thereafter. After losing their previous bass player, they went through several lineup changes before finding permanent bassist Mike Boyne. In 2014, TMGT signed with the Austrian based metal label, Napalm Records, which released TMGT's "Cold Was The Ground" on February 28, 2015. The album had a much faster tempo than previous releases, with more emphasis on song construction. The release boosted their popularity allowing them to appear at major festivals such as Hellfest and Graspop Metal Meeting. Napalm released their fourth full length album "Cypress Ave." on July 28, 2017. Once again progressing into a more mature sound with a wide array of genres. Including a hip hop track featuring Sonny Cheeba from Camp Lo. TMGT has been most commonly described as hard rock, and related to bands like Kyuss, Black Sabbath, and Clutch. The band built the majority of their fan base from consistent touring, and exciting live performances. In 2018 TMGT called it quits in order to focus more on family life, after playing their last show at the Maryland Doom Fest.
 Passage 2:Goswami was born in Guwahati, Assam on 7 March 1973 to an Assamese family. His paternal grandfather, Rajani Kanta Goswami, was a lawyer, a Bharatiya Jana Sangh leader and an independence activist. His maternal grandfather, Gaurisankar Bhattacharyya, was a Communist and leader of the opposition in Assam for many years. He was a writer and a recipient of the Asam Sahitya Sabha Award. Goswami's father is Colonel (Retd.) Manoranjan Goswami and his mother is Suprabha Gain-Goswami. Manoranjan has been a member of the Bharatiya Janata Party and contested the 1998 Lok Sabha Polls as the BJP candidate for the Guwahati to Lok Sabha of Assam where he was defeated by Congress candidate Bhubaneshwar Kalita. His maternal uncle, Siddhartha Bhattacharya, a BJP MLA from Gauhati East constituency, was the head of the Assam unit of the party before Sarbananda Sonowal took over in 2015.
 Passage 3:In the 11th century, Wigginton was under the control of a half-brother of William I, Robert, Count of Mortain. However, in 1086 the Domesday Book indicated that Wigginton had not been gifted to him but was probably acquired by force by Robert from two adjacent estates close to Tring, one of which had previously been in the hands of Edith of Wessex. During the 13th century Wigginton formed part of the estate at Little Gaddesden passing first to the de Broc family and then, through marriage to the de Lucys. After the death of Sir William Lucy in 1466 it was in the ownership of the Corbets for over 130 years. The manor was then the subject of successive legal challenges fought out in the Court of Chancery until it came into the possession of Sir Richard Anderson of the manor of Pendley during the 1650s. Elizabeth Spencer (née Anderson) inherited Wigginton and became the third wife of Simon Harcourt, 1st Viscount Harcourt 1703. The manor remained in the Harcourt family until the 1860s. Colonel Charles Harcourt had died in 1831 leaving the manor to his three daughters, Sarah, Elizabeth and Alice who jointly sold it to Rev. James Williams in 1868. Wigginton Common was enclosed in 1854 and was subsequently incorporated into the Tring Park Estate owned at the time by the Rothschild Family.

Question: Who was Akbar's predecessor to the Mughal throne? Passage 1:Gauda was once the "capital of the ancient bhukti or political division of Bengal known as Pundravardhana which lay on the eastern extremity of the Gupta Empire." During the rule of the Sena Dynasty, in the 11th-12th century, Gauda was rebuilt and extended as Lakshmanawati (later Lakhnauti), and it became the hub of the Sena empire. Gauda was conquered by Muhammad bin Bakhtiyar Khalji in 1205. During the Turko-Afghan period, "the city of Lakhnauti or Gauda continued to function initially as their capital but was abandoned in 1342 by the Ilyas Shahi sultans in favour of Pandua because of major disturbances along the river course of the Ganga." "Pandua then lay on the banks of the Mahananda, which was the major waterway of the sultanate at the time. However, when the Mahananda too began to veer away from the site of Pandua in the mid-15th century, Gauda was rebuilt and restored to the status of capital city by the Hussain Shahi sultans"... With the ascent of Akbar to the Mughal throne at Delhi... the Mughals annexed the ancient region of Gauda in 1576 and created the Diwani of Bengal. The centre of regional power shifted across the Ganga to Rajmahal. Following the demise of the independent sultanate, the regional importance of the Gauda or Malda region declined irreversibly and the city of Gauda was eventually abandoned.
 Passage 2:Karel Bossart was born on February 9, 1904 in Antwerp, Belgium. He graduated in Mining Engineering at the Université libre de Bruxelles in 1924. After winning a scholarship—under the Belgian American Education Foundation—to M.I.T. to study aeronautical engineering he remained in the US working for various aircraft companies. In 1945 he was chief of structures at Convair and proposed to the United States Air Force that a missile could be developed with a range of 8000 km. The Air Force was skeptical of Bossart's proposal, partly wishing to preserve the priority of Strategic Bombers, but granted him a limited contract to develop a prototype. Bossart's major innovation was the use of a monocoque design in which structural support was maintained by pressure within the inelastic fuel tanks. After a series of tests in 1947 the Air Force lost interest and Bossart was instructed to abandon the research, but by 1951 the escalation of the Cold War enabled Bossart to revive the project that became known as 'Atlas'. In 1955 the CIA reported that Soviet Russia had made swift progress on its own ICBM programme and Atlas became a crash project of the highest national importance. Bossart used this opportunity to advance work with high energy cryogenic fuels that resulted in the Centaur upper stage.
 Passage 3:Saint Monan (fl. 6th-7th century) is a legendary saint about whom very little is known. He may have lived in the 6th to 7th centuries. The only description of his life comes from the Brevarium Aberdonense, which was published in Edinburgh in 1509 - 1510. This account has numerous demonstrable errors, but it claims that St. Monan was a companion of Saint Adrian who was with him on the Isle of May when he suffered martyrdom and then went on to Inverey in Fife and set up a chapel. This chapel was rebuilt by David II of Scotland between 1329 and 1371 after he recovered from battle wounds thanks to the intercession of the saint. This place is the modern day St Monans in Fife, Scotland. The only other corroboration for the saint comes from the monks of Ireland who recorded a "Saint Moenenn" for the same feast day as Monan. This Moenenn was a bishop in Ireland.
