Question: Of the two Argentinian figures who gave Fitch awards after his winning the 1951 Gran Premio, who died first? Passage 1:After graduating from New Utrecht High School in Brooklyn, New York, and then attending Columbia College in New York City, Grumbach went on to earn his medical degree from the College of Physicians and Surgeons, Columbia University in 1948. He completed his internship at Mount Sinai Hospital in 1949 and his residency at Babies Hospital, Columbia Presbyterian Medical Center in pediatrics under the direction of Rustin McIntosh in 1951. During the Korean War he served as a captain in the United States Air Force Medical Corps, with assignments at Oak Ridge Institute of Nuclear Studies in Tennessee and at Fort Detrick Biological Laboratories in Maryland. Following his military service, Grumbach did a fellowship with Lawson Wilkins at Johns Hopkins. He then returned to Babies Hospital and Columbia University in 1955, becoming founding director of the Pediatric Endocrine Division at Babies Hospital. In 1966 Grumbach was recruited to the University of California San Francisco as chairman of the Department of Pediatrics, and in 1983 he was named the first Edward B. Shaw Distinguished Professor of Pediatrics. Grumbach served as chairman of the Department of Pediatrics at University of California San Francisco for over two decades, transforming the department into one of the leading academic centers for pediatrics in the country. Grumbach stepped down as Chairman of Pediatrics in 1986 and retired in 1994, but he remained active in the field until December 2014. 
 Passage 2:The singles discography of Wanda Jackson, an American recording artist, consists of seventy-eight singles, nine international singles, one charting b-side, and three music videos. In 1954 at age sixteen, she signed as a country artist with Decca Records. Her debut single was a duet recording with Billy Gray which reached the eighth spot on the Billboard Hot Country Singles chart, also in 1954. Refusing to tour until completing high school, Jackson's further singles for Decca failed gaining success. She signed with Capitol Records in 1956 and began incorporating rock and roll into her musical style. Jackson's first Capitol single exemplified this format ("I Gotta Know") and became a national top-twenty country hit. Follow-up rock singles between 1957 and 1959 failed gaining enough attention to become hits including, "Hot Dog! That Made Him Mad", "Fujiyama Mama", and "Honey Bop". In 1960 however, the rock and roll-themed, "Let's Have a Party", became Jackson's first Billboard top-forty pop hit after it was picked up by an Iowa disc jockey.
 Passage 3:In 1950, Fitch raced his Ford Flathead engined Fiat 1100, which he soon modified into the "Fitch Model B", and ended the year by driving a Jaguar XK120 in the Sebring Grand Prix of Endurance Six Hours. In 1951, in addition to campaigning in his Fitch-Whitmore, he boosted his early reputation by winning the Gran Premio de Eva Duarte Perón – Sport in his Allard-Cadillac J2. As a result of that win, Juan Perón generously awarded him membership in the Justicialist Party, whilst the trophy and a kiss were given by Eva Perón. He also clinched the support of Cunningham, whose financial clout allowed Fitch to race. He was drove a Cunningham C-2 for the Cunningham team at several races, including the 1951 24 Hours of Le Mans, scoring a number of impressive victories in the early ‘50s at then-fledgling road courses like Elkhart Lake and Watkins Glen, and was crowned the first SCCA National Sports Car Champion. In 1951, John raced an Effyh Formula Three car, winning at Bridgehampton and a class win at Giants Despair.

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: When was Les Hanigan's hometown found? Passage 1:A pro runner from Wollongong, Hanigan was selected to represent Southern New South Wales against the touring Great Britain team in 1966, scoring a try. He signed on to play in Sydney's NSWRFL competition with the Manly-Warringah club in 1967. That year he set a new club record for most tries in a match when he scored five tries in a match against competition newcomers, Cronulla-Sutherland. After playing for New South Wales, he scored two tries in Australia's First Test win over New Zealand. By the end of the 1967 NSWRFL season he had scored sixteen tries, the most in the competition, before being selected to tour with the 1967-68 Kangaroos. Hanigan played in 11 games on tour but no Tests. With Manly-Warringah he reached the 1968 NSWRFL season's grand final and played on the wing in the loss to Souths.
 Passage 2:The creek, originally known as the "Esopus Kill", takes its name from the Esopus tribe of the Lenape, who were the Native American residents of the lower Esopus when the Dutch first explored and settled the Hudson Valley in the early 17th century. The creek's wide valley made it an ideal trading route for the Esopus and other Lenape who harvested the beaver pelts the European traders desired. Later, under the English, it became the beginning point for contentious land claims in the mountains. After independence, the Esopus corridor became the main route into the Catskills, first by road then later by the Ulster and Delaware Railroad, for forest-product industries like logging, tanning and charcoal-making. Those industries declined in the late 19th century, shortly before the creation of the Forest Preserve and the Catskill Park made the region more attractive for resorts and recreation, particularly trout fishing. The renewed Esopus also attracted the attention of fast-growing New York City, which was able to acquire land and build the reservoir and tunnel after overcoming local political opposition.
 Passage 3:Belgium was represented at the 1970 edition by Daliah Lavi, famous for her role in Casino Royale (1967), the James Bond parody featuring Woody Allen as well with Samantha Gilles in 1987 ending second with the song Hold Me. Lavi performed the chanson "Prends L'Amour" and ended up 13th in the Grand Final (the contest had two semi-finals and one final). The Netherlands delegated world-known jazz singer Rita Reys with the song "Just Be You", a composition by her husband Pim Jacobs. Czech singer Helena Vondráčková sang "Uncle Charlie" a novelty song inspired by Charlie Chaplin. Other famous 1970 participants were 1969 Eurovision winner Frida Boccara for France, Jacques Michel for Canada and Ted Mulry for Australia, who scored a national number 1 hit with his entry. Winner of the 1st WPSF was Israel with the duo Hedva & David. More than 2 million copies of their winning entry "Ani Holem Al Naomi" ("I Dream Of Naomi") were sold worldwide, giving a serious credibility boost to the new Festival.
