[Q]: 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.

[Q]: Question: Who was the lead design person for the German Type IXC submarines? Passage 1:Rafael Casanova i Comes () (Moià, 1660 – Sant Boi de Llobregat, 2 May 1743) was a Catalan jurist, and supporter of Charles VI, Holy Roman Emperor as a claimant to the Crown of Spain during the War of the Spanish succession. He became mayor of Barcelona and commander in chief of Catalonia during the Siege of Barcelona until he was wounded in combat while commanding La Coronela during the counterattack on the Saint Peter front on the last day of the siege, September 11, 1714. After the war he received a royal pardon for having supported the Habsburg claim to the Spanish throne. He recovered from his wounds, and continued his fight against absolute monarchy as a lawyer. It has been claimed that he is the author of the book Record de l'Aliança fet el Sereníssim Jordi Augusto Rey de la Gran Bretanya (Remembrance of the Alliance to George I of Great Britain) in which Catalonia reminds England of the Treaty of Genoa and their obligation to Catalonia.
 Passage 2:After the fourth single release "Willy Use a Billy... Boy", released in 1995 and peaked #5 in Austria, later in June 1996, both members left the band, due to a disagreement between Leigh and producer Brandes, who were quickly replaced by artists Jeane (Jeanette Macchi-Meier) and briefly Terence D'Arby (not to be confused with Terence Trent D'Arby), who himself again was replaced by Ché Jouaner. Thus it has been later revealed, that Brandes was the rapper on all E-Rotic releases, except on the first album, where he shared raps with Raz-Ma-Taz, such on "Take My Love", and Leigh still had to continue to provide vocal work for E-Rotic's four follow up studio albums The Power of Sex, Sexual Madness, the Abba cover album Thank You for the Music until 1999 to the Kiss Me studio album due to her contract. Also, raps on their first single "Max Don't Have Sex With Your Ex" were not done by Smith or Brandes, but instead were done by Marcus Thomas (aka Deon Blue) who would later join Pharao. Meanwhile, Leigh, alongside Raz-Ma-Taz, formed her own band S.E.X. Appeal in 1996. "He promised me a lot of things during my E-Rotic time, but never was willing to keep his promises. One of these promises was to produce a mixed video, with both cartoon and real people. We were never shown in the videos and so we had problems with our concerts, cause no-one really knew us as persons," Leigh revealed. On 27 June 1996, the group's second studio album The Power of Sex was released, preceded by the latter mentioned lead single "Willy Use a Billy... Boy" and followed by the singles "Help Me Dr. Dick", "Fritz Love My Tits" and "Gimme Good Sex", all becoming moderate chart hits, peaking at #18, #16 and #3 in Austria respectively. In 1996, E-Rotic were featured in the supergroup, called "Love Message", on the same titled, Masterboy-produced charity single "Love Message". They also appeared on the Queen tribute compilation album Queen Dance Traxx, with the song "Who Wants to Live Forever", which also saw a promotional release. The tribute album also featured another Queen song "We Are The Champions", recorded with all artists, who participated on Queen Dance Traxx as a supergroup labeled as "Acts United". In 1997, the studio albums "Sexual Madness" and the Abba cover CD Thank You for the Music was released with its single releases "Turn Me On", which peaked at #7 in Finland, "Thank You for the Music" and "The Winner Takes It All". The album Thank You for the Music was released under the artist name "Jenn and C." in France. Ironically the music video for "Gimme Good Sex" was also the first one, not being a comic video, but still it never aired and was banned from music channels because of being too controversial for its sexual content, thus Leigh, alongside Raz-Ma-Taz, left the band earlier, because she wanted to be shown in music videos.

 Passage 3:The first obelisks may start to appear in the later 16th century and it is suggested that the obelisk on Compton Pike is Elizabethan in date. More securely dated is a series of obelisks which start to appear in the 18th century. The first of these was the Wakeman obelisk of 1702 by Nicholas Hawksmoor, which is set in the square at Richmond, Yorkshire. Probably several hundred obelisks exist in the British Isles dating from 18th and early 19th centuries. Most of these obelisks, which are often landmarks commemorate famous people and their achievements. At Stowe in Buckinghamshire an obelisk was erected in memory of Wolfe's victory at Quebec in 1752, while at the death of the Duke of Cumberland in 1765 was noted by an obelisk at Englefield Green in Surrey. Thomas Coke, Earl of Leicester, Coke of Norfolk the farming pioneer has a particularly fine obelisk, set up in the park he created at Holkham in Norfolk. Sometimes an obelisk was used to mark the site of a battle such as the obelisk on the site of English Civil War battlefield at Naseby in Leicestershire. Occasionally obelisks are used as mile markers, as on the Great North Road at a mile from Westminster. In Lincoln an elaborate obelisk was set up on the High Bridge in 1762–63 as a conduit for dispensing water, while Anthony Salvin used obelisks as water fountains on the Belton House estates in Lincolnshire.
