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.

Example 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.

Example Input: Question: Who was the host of the Olympics where Henry Littlewort won a gold medal? Passage 1:Due to a double election of François Louis, Prince of Conti and the Frederick Augustus I, Elector of Saxony (elected King of Poland as Augustus II) in 1697, the two claimants to the Polish throne had serious troubles with obtaining approval of the nobility for their coronation. The most difficult situation was of Elector of Saxony, who had no support of the primate Michał Stefan Radziejowski and most of the senators holding the custody of the Wawel Castle Crown Treasury. Therefore, expecting obstacles in obtaining the royal insignia, he ordered to prepare replacements before his arrival to Kraków. On the eve of the ceremony, some of the gathered decided to find a way to obtain the original regalia. Two monks Aleksander Wyhowski, prior of Czerwińsk and Mikołaj Wyżycki, prior of the Holy Cross made a hole in the castle's wall and got to the vault from which they stole the crown, scepter, sword and orb. The Dresden regalia become unnecessary, Augustus II the Strong, however, treated them as a private insignia.
 Passage 2:Crystal Palace started their second season in a new division, having gained promotion from the Southern League Division Two the previous season. There were a number of personnel changes this season, with Archie Grant and captain Ted Birnie moving to Chelsea and George Walker going to New Brompton. Palace's hat-trick hero in their FA Cup exploits of last season, Walter Watkins, also moved on to Northampton Town. In their places Palace brought in a number of new faces. Charles Ryan joined from Nunhead, Thomas Wills from Newcastle, Bill Forster from Sheffield United and Bill Ledger from Pryhope Villa. Wilf Innerd was made captain and played in all but one of the club's League and Cup matches. The club struggled to find their feet on the new division, and failed to score in 13 of their matches, finishing the season in 19th position, one place off the bottom. This was enough to ensure safety though, as for this season there was no relegation. Palace again called on a number of amateurs from the local area and beyond, including Henry Littlewort. Littlewort, who made his only appearance for the club this season, would go on to win a gold medal with the British Football team in the 1912 Olympics.
