Question: In what country is the Nikos Kazantzakis Stadium located? Passage 1:The «Nikos Kazantzakis» Stadium (), formerly known as Ergotelis Stadium and more commonly as Martinengo Stadium, is a football stadium located on the Martinengo bastion, part of the fortifications of Heraklion, on the island of Crete. It is named after Modern Greek literature giant Nikos Kazantzakis, whose grave is also located on the same bastion. It is part of the Ergotelis Athletic Centre, a sport facilities complex owned by Greek multi-sport club Ergotelis. Built in 1946, as Ergotelis Stadium (), it was the traditional home ground of Greek football club Ergotelis until 2004, when the club moved to the Pankritio Stadium, Heraklion's largest and most modern sports venue. The complex currently houses the Ergotelis Youth Academy, the largest youth sports academy on the island of Crete, and one of the largest in Greece, while the stadium itself is still used as the home ground of multiple Heraklion football clubs playing in the Heraklion Football Clubs Association amateur league system. It has a capacity of about 1,000 spectators, of which approximately 600 can be seated.
 Passage 2:During the First Sino-Japanese War he was an attaché with the Chinese Army, and on 12 February 1897 he was promoted to major. After service as the Deputy Assistant Adjutant General (DAAG) for Dublin and Aldershot Districts, he was in January 1900 appointed Deputy Assistant Adjutant General for the 8th Division South African field force, created to take part in the Second Boer War in South Africa. He left Southampton in the SS Moor in March 1900 with the staff of the 8th division and 600 men of militia regiments, arriving in Cape Town the next month. In South Africa, he took part in operations about Dewetsdorp and Thabanchu during the relief of Wepener (April 1900), the occupation at Senechal, and the action at Biddulphsberg (May 1900). He was DAAG for intelligence during the operations in the Wittebergen and Nordebergen, resulting in the surrender of Boer Commandant Prisloo in July 1900. Later that year he took part in the occupation of Harrismith and the action at Doornberg (Sep 1900) where he was wounded, then served for the duration of the war in the Orange River Colony. Following the end of the war with the Peace of Vereeniging on 31 May 1902, he returned home on the SS Dilwara which arrived at Southampton in late October 1902. For his service in the Boer war he was mentioned in despatches, received the Queen's South Africa Medal with two clasps, and was appointed a Companion of the Order of St Michael and St George (CMG).
 Passage 3:Sydnor and Herc watch as Marlo meets with his lieutenants. Marlo makes a phone call about picking up a "skinny girl from New York," which Herc interprets as an arrangement to pick up a supply of cocaine. Herc follows Marlo to Penn Station and has him arrested when he meets a woman who turns out to not be carrying drugs. Marlo has engineered the incident to draw out the police. Meanwhile, Greggs learns that a prisoner has offered information on the dead state's witness. However, Rawls tells Landsman to detail Greggs and Norris to uniformed duty at the polls, stalling the witness case until after the election. At school, Prez offers to help Dukie get clean clothes. Donnelly and Grace remove Namond from regular class and put him in Colvin and Parenti's study program along with nine other students. When Randy is brought to Donnelly concerning a potential sexual assault case with a female student, he reveals that he knows about a murder. Later, Prez appeals to Donnelly to let him hand Randy's confession on to someone that he trusts in the police.

Question: Where was McMahon's post-doctoral mentor from? Passage 1:Ain't She Sweet was an American album featuring four tracks recorded in Hamburg in 1961 by The Beatles featuring Tony Sheridan (except for the title song with vocal by John Lennon) and cover versions of Beatles and British Invasion-era songs recorded by the Swallows. As Atlantic Records only had rights to four Sheridan/Beatle recordings recorded by Polydor Records, they filled the rest of the album with Beatle and British Invasion cover songs. When this material was released by Atco Records, there were mono (catalogue number 33-169) and stereo (SD 33-169) editions. Atco also added additional drum overdubs to the four Sheridan cuts on top of the original drum tracks. American drummer Bernard Purdie claims to have performed overdubs of unspecified Beatles records, which would most likely have been for Ain't She Sweet, but this has never been officially confirmed.
 Passage 2:McMahon contributed to the understanding of retinal neurophysiology alongside his post-doctoral mentor, John E. Dowling. His early research focused on ion channels that mediate transmission at electrical and glutamatergic synapses and the modulatory effects of dopamine and nitric oxide on retinal synapse networks. Through studies with zebrafish he discovered that the neurotransmitter dopamine decreases the electrical coupling within horizontal cells. Further research showed that it was the increase of cAMP within the cell resulting from dopamine binding to AMPA receptor that led to this decrease in coupling. McMahon and his colleagues also demonstrated that exogenous nitric oxide and zinc can modulate AMPA receptor mediated synaptic transmission at gap junctions in hybrid bass retinal neurons.
 Passage 3:The river starts at Ralph Bice Lake (formerly Butt Lake) in northern Algonquin Provincial Park in the geographic township of Butt in the Unorganized South Part of Nipissing District. It flows south to Daisy Lake then east to Big Trout Lake. The river heads north out the lake over Big Trout Lake Dam, takes in the left tributary Tim River, flows over the Portal Rapids, Cedar Rapids, Snowshoe Rapids, Catfish Rapids, and Stacks Rapids to reach Cedar Lake, the location of the community of Brent, where it takes in the left tributary Nipissing River. The river exits the lake over a dam, heads through the Devil's Chute, reaches Radiant Lake, where it takes in the left tributary North River and right tributary Little Madawaska River, and passes through the Squirrel Rapids, Big Sawyer Rapids, Battery Rapids Cascade Rapids and White Horse Rapids, and takes in the right tributary Crow River. The river then continues through a series of rapids including the Devil's Cellar Rapids, passes the Algonquin Radio Observatory, and reaches Lake Travers. The Petawawa River enters a canyon and passes through numerous rapids including the Big Thompson Rapids, Little Thompson Rapids, Grillade Rapids, Crooked Chute, Rollway Rapids, The Natch, Schooner Rapids, Five Mile Rapids to arrive at Whitson Lake adjacent to the Petawawa Hills. It leaves Algonquin Provincial Park and enters the municipality of Laurentian Hills in Renfrew County, continues southeast past CFB Petawawa, passes through the Crooked Rapids, Race Horse Rapids, White Horse Rapids and Halfmile Rapids, and reaches Lac du Bois Dur, where it takes in the right tributary Barron River. The river enters the town of Petawawa, heads under Ontario Highway 17, through the Big Eddy Rapids, under the Canadian Pacific Railway main line, and empties into Black Bay on the Ottawa River.

Question: What year was the company founded that Chillag worked for in England? Passage 1:A member of the Aspietes family, of noble Armenian origin, Constantine was probably a close relative of his contemporary Michael Aspietes, a distinguished general killed in 1176. Like his relative, Constantine too had earned distinction during Manuel I Komnenos' campaign against the Hungarians in 1167. The historian John Kinnamos records that he held the rank of sebastos. He is next recorded as being active in 1190/1, during the Byzantine efforts to suppress the Bulgarian–Vlach rebellion of the brothers Peter and Ivan Asen. The historian Niketas Choniates records that, in an effort to sustain the troops and bolster their morale, Aspietes decided to distribute to them their delayed annual salaries. This act, however, enraged Emperor Isaac II Angelos, who saw in it almost an attempt to bribe the army to support Aspietes in overthrowing him. The emperor had Aspietes arrested and blinded, after which nothing further is known of him. He possibly died in the early years of the 13th century.
 Passage 2:SR 510 begins as Marvin Road at exit 111, a diamond interchange on (I-5) in southern Lacey. The highway travels south by the Hawks Prairie Village Mall, home of the Hawks Prairie Center, a division of the South Puget Sound Community College. South of the mall is the Martin Way intersection, located west of River Ridge High School and one of the busiest intersections on the roadway at a daily average of 24,000 motorists in 2008, and the Pacific Avenue roundabout, where SR 510 turns east, renamed Pacific Avenue, northeast of Long Lake. After leaving Lacey city limits, the roadway begins to parallel the Quadlok line owned by Tacoma Rail south towards the Old Pacific Highway. At the Old Pacific Highway, the road becomes the St. Clair Cutoff Road, named for nearby Saint Clair Lake, and crosses the railroad tracks twice. After turning northeast, parallel to Saint Clair Lake's shoreline, the highway dips southeast, now parallel to the Nisqually River, into Fort Lewis and the Nisqually Indian Community. Outside of the community, SR 510 is renamed the Yelm Highway and passes Southworth Elementary. After intersecting Mudd Run Road, future western terminus of the Yelm Loop, the roadway enters Yelm city limits. After turning southeast, SR 510 becomes Yelm Avenue and serves Yelm High School. Shortly thereafter, the roadway serves Yelm Middle School, crosses the Yelm-Tenino Trail, a long rail trail in operation since 1993, and ends at First Street, signed as , which continues southeast as Yelm Avenue.
 Passage 3:Chillag emigrated to Australia after the war, having found no surviving family back in Hungary and being unable to remake the family business following the arrival of communism. Marrying a British-born expatriate in 1950, he worked for the Australian Atomic Energy Commission between 1957 and 1963, living in Sydney. He moved to Leeds, England in 1962, to work in Boston Spa until retirement, whereupon he became a European Information Officer for Leeds Metropolitan University. His daughter, diagnosed with Down syndrome, prompted him to work voluntarily with Mencap, and he continued to give lectures on his experiences at the Imperial War Museum. In 2004, he published his memoirs, The Odyssey of John Chillag, a Hungarian Jew Born in Vienna 2006: From Győr in Hungary to Australia and England Via Auschwitz and Buchenwald.
