Question: 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: Question: The rightful heir to the Hungarian throne according to the Treaty of Nagyvarad was a king from which country? Passage 1:The famous and influential Swedish filmmaker, Ingmar Bergman, rose to prominence in the fifties. He began making films in the mid-forties, and in 1955, he made Smiles of a Summer Night, which brought him international attention. A year later, he made one of his most famous films, The Seventh Seal. In the 1960s, Bergman won the Academy Award for Best Foreign Language Film for two consecutive years, with The Virgin Spring (Jungfrukällan) in 1960 and Through a Glass Darkly (Såsom i en spegel) in 1961. He won the award again in 1983, for the early twentieth-century family drama Fanny and Alexander (Fanny och Alexander). Bergman has also been nominated for the Best Picture award once, with the 1973 Cries and Whispers (Viskningar och rop), the story of two sisters watching over their third sister's deathbed, both afraid she might die, but hoping she does. The film lost to The Sting, and oddly enough, it was not nominated in the Foreign Language Film category. It also gave Bergman the first of three nominations for Best Director. Ingmar Bergman also won four Golden Globe Awards for Best Foreign Language Film.
 Passage 2:Auckland was New Zealand's second capital from 1841 until 1865, when Parliament was permanently moved to Wellington after an argument that was had for one decade. The initial form of government was an executive council formed of public servant appointed by and responsible to the governor. This changed when the New Zealand Constitution Act 1852, an Act of the Parliament of the United Kingdom that granted self-government to the Colony of New Zealand, was received. This allowed for a bicameral General Assembly (or Parliament), consisting of the Governor, an appointed Legislative Council and an elected House of Representatives, with an Executive Council nominally appointed by the Governor. It also allowed for provincial governments, and six provinces were initially established. The first general election was held in 1853.
 Passage 3:In 1530 John Zápolya appointed him as the provost of the Buda cathedral and as a royal secretary. Between 1530-1539 he was also the deputy of the King and after his death he remained with his widow, Isabella Jagiellon. In 1541 he moved with her to Transylvania, but he mostly traveled fulfilling diplomatic services because of his disagreement with cardinal Juraj Utješinović's policy of claiming the Hungarian throne for Isabella's and Zápolya's infant son (instead of conceding it to Ferdinand I as per Treaty of Nagyvárad). Utješinović, appointed by Zápolya as a guardian of his son, John Sigismund Zápolya, fought against Ferdinand and allied himself with the Ottoman Empire.

Question: Question: Where is the network headquartered that hosted the amateur film competition that Rose won? Passage 1:Ardley was born in Epsom, Surrey. Signed by Wimbledon as a youngster, whilst at Carshalton Boys Sports College, he made his way through the youth set up until breaking into the first team. Ardley made eight league appearances for Wimbledon in the 1991–92 season, featuring more prominently in the 1992–93 campaign, in which he played in 26 games and scored four goals in the inaugural season of the FA Premier League as the Dons finished 12th. Wimbledon finished 6th in the FA Premier League in 1993–94, matching the record highest ranking achieved by the club during their first ever season in the top flight during 1986–87. Ardley's contribution was more limited during this season, however, as he was selected to play in just 16 games. He scored just once in a 2–1 win over Sheffield Wednesday on 15 January 1994. He was in and out of the side for nearly a decade afterwards, remaining with the Dons after their relegation at the end of 1999–2000. Two more seasons followed as he unsuccessfully tried to help them regain their Premier League place, before he signed for Division One rivals Watford on a free transfer on 9 August 2002.
 Passage 2:Rose was born in London, the son of a Jewish father and a mother who had converted to Judaism. He began making super 8 films when he was 9. By 1975, he won an amateur film competition hosted by BBC which led to the broadcasting of his works. He worked for Jim Henson on the last season of The Muppet Show and then again on The Dark Crystal in 1981. He attended National Film and Television School and graduated in 1982 with a Master's in Filmmaking. After this, he moved on to directing music videos for MTV, one of which was the uncensored version of Frankie Goes To Hollywood's hit "Relax".
 Passage 3:"Piece of Me" was co-written and produced by the Swedish duo Christian Karlsson and Pontus Winnberg, professionally known as Bloodshy & Avant, along with Klas Åhlund. While recording with Spears over the years, Karlsson and Winnberg often saw first-hand how her regular activities were interrupted by the paparazzi, including one experience in Hamburg which Winnberg deemed "really scary". For Blackout, Spears worked with them on "Radar", "Freakshow" and "Toy Soldier". When the album was considered to be finished, Bloodshy & Avant were persuaded by her A&R Teresa LaBarbera Whites to work on a new track. Winnberg commented that it had always been an unwritten rule not to write songs about Spears's personal life since the label rejected "Sweet Dreams My LA Ex", a response track to Justin Timberlake's "Cry Me a River". However, the duo wrote "Piece of Me" with Åhlund and sent it to Spears, who loved it. Bloodshy & Avant worked on the track at Bloodshy & Avant Studios in Stockholm, Sweden, and Spears recorded her vocals at Chalice Recording Studios in Los Angeles, California. Winnberg stated that Spears was extremely psyched when she came to the studio, where she recorded the song in about half an hour as she had learned the lyrics by heart in her car. "Piece of Me" was later mixed by Niklas Flyckt at Mandarine Studios in Stockholm. On October 31, 2007, during a radio interview with Ryan Seacrest, Spears talked about the song, saying,
