In this task, you're given a question, along with three passages, 1, 2, and 3. Your job is to determine which passage can be used to answer the question by searching for further information using terms from the passage. Indicate your choice as 1, 2, or 3.

Input: Consider Input: 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.

Input: Consider Input: Question: Does the team Carter debuted on still exist today? Passage 1:The northern segment of the fault runs from Hollister, through the Santa Cruz Mountains, epicenter of the 1989 Loma Prieta earthquake, then up the San Francisco Peninsula, where it was first identified by Professor Lawson in 1895, then offshore at Daly City near Mussel Rock. This is the approximate location of the epicenter of the 1906 San Francisco earthquake. The fault returns onshore at Bolinas Lagoon just north of Stinson Beach in Marin County. It returns underwater through the linear trough of Tomales Bay which separates the Point Reyes Peninsula from the mainland, runs just east of Bodega Head through Bodega Bay and back underwater, returning onshore at Fort Ross. (In this region around the San Francisco Bay Area several significant "sister faults" run more-or-less parallel, and each of these can create significantly destructive earthquakes.) From Fort Ross, the northern segment continues overland, forming in part a linear valley through which the Gualala River flows. It goes back offshore at Point Arena. After that, it runs underwater along the coast until it nears Cape Mendocino, where it begins to bend to the west, terminating at the Mendocino Triple Junction.
 Passage 2:In 2010, the Scorpions announced their farewell tour. Before they retire, they wanted to release a bonus track album from leftovers from seventies and eighties just for the fans. After playing the final show in Munich in December, 2012, band planned to take a break and go on vacation. In January, 2013, MTV contacted the band and asked if they are interested in doing the MTV Unplugged album. They agreed on doing that project and turned out to be successful. That whole thing pushed back the bonus track project. As soon as they have finished the MTV Unplugged project, band immediately went back to studio to work on bonus track project. Band was listening the recordings they have already prepared for the project. They were happy with the result and Rudolf Schenker said that he has a tape with some songs that they could also use for this project. While searching for the tape, Schenker found an old ledger in which his mother enumerated the loans that his father provided to him, so he could buy all the equipment and establish the band. He looked into the book and it said: "September, 1965". He went back to the studio and told the band what he found and their manager said that it would be great idea to celebrate 50th Anniversary since they are the only German band who is 50 years in music and one of the few in the world along with The Rolling Stones, The Who, Beach Boys and Pink Floyd. Manager suggested to the band that they contact the promoters and see if they are interested in band doing the 50th Anniversary Tour. Then Schenker suggested that if band is going to do a 50th Anniversary Tour, then band needs to release brand new studio album. So the band went again into the listening process of bonus track material that they have already prepare and see if they can improve something, like choruses and riffs. After that, they re-recorded the old stuff and started to write new songs with the producers Mikael Nord Andersson and Martin Hansen. The result was the album Return to Forever.
 Passage 3:Carter started his career as an apprentice at Brighton & Hove Albion but failed to make the grade for the first team. He made his first team debut in April 1987 in a 1–1 draw with Blackburn Rovers, coming on as a substitute and almost scoring with his first touch. He subsequently dropped down to the Isthmian League where he spent a season with Billericay Town. He was signed by Fourth Division side Leyton Orient in July 1988 and remained a first team regular in his seven-year spell at the club, which included promotion to the Third Division in his first season with via the play-offs. In June 1995, he joined newly relegated Second Division side Peterborough United for a fee of £25,000. He was a first team regular in his first season with the club but dropped out of the side in his second season as the club narrowly avoided relegation twice. Following his release he spent time on trial at Cambridge United and Wycombe Wanderers, however, both were unsuccessful in earning a full-time contract. He subsequently signed for Welsh Premier League side Barry Town, where he spent two seasons and made a total of sixty league appearances, scoring ten goals. He later joined Southern League Premier side Merthyr Tydfil in 1999 and spent six seasons with the club making over 200 appearances. He was also the club captain. In the summer of 2005 he signed for newly promoted Welsh Premier League side Cardiff Grange Harlequins but only made eight league appearances and the side couldn't avoid relegation at the first attempt.

Input: Consider Input: Question: Which of the actors that played Dr. Tom Friend and Ed Shelley died most recently? Passage 1:Dr. John Rollason (Peter Cushing), his wife, Helen (Maureen Connell), and assistant, Peter Fox (Richard Wattis), are guests of the Lama (Arnold Marlé) of the monastery of Rong-buk while on a botanical expedition to the Himalayas. A second expedition, led by Dr. Tom Friend (Forrest Tucker) accompanied by trapper Ed Shelley (Robert Brown), photographer Andrew McNee (Michael Brill) and Sherpa guide Kusang (Wolfe Morris), arrives at the monastery in search of the legendary Yeti or Abominable Snowman. Rollason, despite the objections of his wife and the Lama, decides to join Friend's expedition. Whereas Rollason is motivated by scientific curiosity to learn more about the creature, Friend seeks fame and fortune and wants to capture a live Yeti and present it to the world's press.
 Passage 2:Amos of Tekoa delivered a speech at the Temple of the Golden Calf in the city of Bethel in the northern kingdom of Israel just "two years before the earthquake" (), in the middle of eighth century BC when Uzziah was king of Judah and Jeroboam II was king of Israel. Amos spoke of the land being shaken (), houses being smashed (), altars being cracked (), and even the Temple at Bethel being struck and collapsing (). The Amos' Earthquake impacted Hebrew literature immensely. After the gigantic earthquake, no Hebrew prophet could predict a divine visitation in judgment without alluding to an earthquake. Just a few years after the earthquake, Isaiah wrote about the "Day of the Lord" when everything lofty and exalted will be abased at the time when the Lord "ariseth to shake terribly the earth" (). Then, Isaiah saw the Lord in a temple shaken by an earthquake (). Joel repeats the motto of Amos: "The Lord also will roar out of Zion, and utter his voice from Jerusalem," and adds the seismic theophany imagery "the heavens and the earth shall shake" (; compare ). After describing a future earthquake and panic during the "Day of the Lord" at Messiah's coming to the Mount of Olives, Zechariah says, "Yea, ye shall flee, like as ye fled from before the earthquake in the days of Uzziah king of Judah" (Zechariah 14:5). The panic caused by Amos' Earthquake must have been the topic of legend in Jerusalem, because Zechariah asked his readers to recall that terrifying event 230 years later.
 Passage 3:Originally it was planned to open in summer 2003, but the big success of Finding Nemo forced the studio to move the release date one more time, now for the Thanksgiving holiday season also putting in production over 30 theatrical shorts (not only Looney Tunes, also some Tom and Jerry cartoons – many story-boarded and directed by co-creator Joe Barbera and Hanna-Barbera veteran Iwao Takamoto- such as The Karate Guard) However, the release date of the film proved fatal to the film's performance. On the family front, the film was sandwiched between the releases of Elf and The Cat in the Hat, resulting in  being lost in the shuffle. It should also be noted that this film was released the same month as another Warner Bros. film The Matrix Revolutions, which the studio put more advertising money behind; and a few weeks before the much-hyped release of  (which like Elf, it was coincidentally distributed by New Line Cinema -then a sister company to WB-, which would later be folded into Warner Bros.). Only the barest minimum of promotions were done to advertise the film, limited to advertising with the film's promotional partners, very few television ads, and the release of very little merchandise directly based on the film. Additionally, the film was released in a period in which international tension caused by the Iraq War caused audiences to not want to see action films for some time, and retained a PG rating -now considered to be a children-focused rating- (which alienated its target teen audience). All of these factors made the movie result in a box-office flop (although getting positive reviews), forcing Warner Bros. to reorganize the entire cartoon unit, now focused on television. Only 11 of the shorts were completed and the Looney Tunes shorts have been released on DVD, while the Tom and Jerry cartoons were shown as part of Tom and Jerry Tales (except for The Karate Guard which received limited theatrical release in 2005). See also: Tom and Jerry.
