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.

[EX Q]: Question: What country was Thomas stationed in while serving with the 550 Squadron? Passage 1:The fruit bodies of A.abrupta grow on the ground, typically solitary, in mixed conifer and deciduous forests, usually during autumn. The frequency with which fruit bodies appear depends on several factors, such as season, location, temperature, and rainfall. The mushroom has been described as common in the Southeastern United States; in Texas, it has been called both infrequent, and common in the Big Thicket National Preserve. Like most other Amanita species, A.abrupta is thought to form mycorrhizal relationships with trees. This is a mutually beneficial relationship where the hyphae of the fungus grow around the roots of trees, enabling the fungus to receive moisture, protection and nutritive byproducts of the tree, and affording the tree greater access to soil nutrients. Amanita abrupta is widely distributed throughout eastern North America, where it has been found as far north as Quebec, Canada, and as far south as Mexico. Orson K. Miller claims to have found it in the Dominican Republic where it appeared to be growing in a mycorrizhal association with pine trees. Kuo also mentions a mycorrhizal relationship with both hardwoods and conifers, while Tulloss lists additional preferred tree hosts such as beech, birch, fir, tsuga, oak, and poplar. However, A.abrupta has been shown experimentally to not form mycorrhizae with Virginia Pine.
Passage 2:In 2006, , a first-year dramaturgy student at the University of Arts' Faculty of Dramatic Arts (FDU), wrote a script based on the "Balada o Pisonji i Zugi" track as part of an assignment in school. Though it mostly relies on "Balada o Pisonji i Zugi", the script also references other Zabranjeno pusenje songs such as "Pamtim to kao da je bilo danas", "Lutka sa naslovne strane", "Hadzija il bos", "Murga drot", "Guzonjin sin", and "Pisonja i Zuga u paklu droge". urevic placed the plot in summer 1990 on the eve of the Yugoslavia vs. West Germany match at the 1990 FIFA World Cup with two lifelong friends from Sarajevo of differing ethno-religious backgrounds and football club loyalties (Pisonja, a Muslim who's a fan of FK Sarajevo, and Zuga, a Serb pulling for FK Zeljeznicar) trying to get to Dubrovnik.
Passage 3:Ward Thomas joined RAF Bomber Command in 1941 and trained as a navigator and pilot in South Africa. He joined 100 Squadron as a Lancaster pilot and was later moved to 550 Squadron stationed in Grimsby. He flew 36 trips over France and Germany over the course of the war, including taking part in the Nuremberg raid of March 1944 during which Bomber Command suffered its heaviest loses. He was awarded the Croix de Guerre for his involvement in bombing raids on the German Panzer training camp at Mailly-le-Camp in advance of the Normandy landings in June 1944. He also received the DFC "for utmost fortitude, courage and devotion to duty in air operations" during the War. By the time he left the RAF Ward Thomas had achieved the rank of flight lieutenant.

[EX Q]: Question: How well rated was the episode where the ninth doctor morphed into the tenth? Passage 1:In 1902 Vice President Theodore Roosevelt requested that Marshall Bond assist Roosevelt's cousin Leila's husband Edward Reeve Merritt, a Bond friend, to help a group of Boer refugees purchase ranchland and establish a colony in Mexico. Judge Hiram Bond's cattle dealing at Villa Park Ranch near Denver had included some previous experience with purchases from and sales to ranchers in Mexico. After Marshall Bond and Edward Reeve Merritt met and negotiated with Jose Yves Limantour and other federal officials in Mexico City and visited various potential sites, they bought a large ranch Hacienda Humboldt from Governor Luis Terrazas on the Rio Conchos in the municipality of Julimes near Delicias, Chihuahua. For more, see Creel-Terrazas Family. The Boers managed to farm there for about fifteen years, until they were displaced as farmers and managers by native Mexicans who were supported by populist labor agitators.
Passage 2:The regeneration of the Ninth Doctor into the Tenth at the end of "The Parting of the Ways" (2005) used computer effects to morph Christopher Eccleston into David Tennant. In the episode of Doctor Who Confidential accompanying the episode "Utopia" (2007), where the same effect is used for the Master's regeneration, it is stated that the production team decided that this would be a common effect for all future Time Lord regenerations, rather than each regeneration being designed uniquely at the whim of the individual director. This style of transition is seen again in "The Stolen Earth"/"Journey's End" (2008) both when the Doctor undergoes an aborted regeneration, and when his hand spawns a clone in the second part; in The End of Time (2010) during which Matt Smith took over the role as the Eleventh Doctor; in "The Impossible Astronaut" when the Doctor is shot twice and seemingly killed; in "Day of the Moon" when a young girl regenerates; and in "Let's Kill Hitler" when Mels (Nina Toussaint-White) is shot and regenerates into River Song (Alex Kingston). "The Night of the Doctor" and "The Day of the Doctor" subsequently use the effect to show the Eighth Doctor and War Doctor's regenerations respectively. The Eighth Doctor's regeneration into the War Doctor uses steady beams of light as opposed to the flame effect used for other revived series regenerations. In the Series 10 episode "The Lie of the Land", the Twelfth Doctor fakes a regeneration as part of a plan to test if Bill still has free will. The effect used is consistent with the one used in the modern series, with the Doctor's hands glowing and emitting regeneration energy before he enters full regeneration. However, as the regeneration was not real, it did not use up a regeneration and the Doctor did not change bodies.
Passage 3:Cross began his career at Walsall, who finished 12th in the Third Division in 196667 under the stewardship of Ray Shaw. New boss Ron Lewin then took the "Saddlers" to a seventh-place finish in 196768. After a 13th-place finish in 196869, Bill Moore returned to lead Walsall to 12th place in 196970. Cross played just 12 league games in his four years at Fellows Park. He joined Gordon Lee's Port Vale in July 1970. He made his debut on 5 September, in a 10 win over Preston North End at Vale Park. He played 42 Third Division games in the 197071 season, and scored his first goal in the Football League on 2 January, in a 21 win over Doncaster Rovers at Belle Vue. He was an ever-present in the 197172 season, playing all 46 league and five cup games. He made 40 appearances in the 197273 season, and ended a series of 134 consecutive appearances from his debut in March 1973 when he wrenched his left knee. He recovered from this injury to play just two games in the 197374 campaign, but then he injured his knee ligaments in October 1973 and was out of action for 17 months. He managed to play just two games in the 197475 season, and was handed a free transfer in May 1975 by new manager Roy Sproson. He went on to play for Southern League side Nuneaton Borough. Upon his retirement as a player, he became a School of Excellence coach at Stoke City. He later went on to become a teacher for 25 years.

[EX Q]: Question: How old was Moore when he was promoted to Lieutenant Colonel? Passage 1:The Battle of Ia Drang was the first major battle between the United States Army and the People's Army of Vietnam (PAVN), also referred to as the North Vietnamese Army (NVA), and was part of the Pleiku Campaign conducted early in the Vietnam War. It comprised two main engagements, centered on two previously scouted helicopter landing zones (LZs), known as LZ X-Ray and LZ Albany. The first involved the 1st Battalion, 7th Cavalry Regiment and supporting units under the command of Lieutenant Colonel Hal Moore, and took place November 1416, 1965 at LZ X-Ray, located at the eastern foot of the Chu Pong Massif in the central highlands of Vietnam. The second engagement involved the 2nd Battalion, 7th Cavalry Regiment plus supporting units under the command of Lieutenant Colonel Robert McDade, and took place on November 17 at LZ Albany, farther north in the Ia Drang Valley. It is notable for being the first large scale helicopter air assault and also the first use of Boeing B-52 Stratofortress strategic bombers in a tactical support role. Surrounded and under heavy fire from a numerically superior force, the American forces at LZ X-ray were able to hold off and drive back the North Vietnamese forces over three days of battle, largely through the support of both air power and heavy artillery bombardment, which the North Vietnamese lacked. LZ X-ray was considered an American tactical victory, as the Americans were able to exact an almost 10:1 kill ratio. At LZ Albany, the American forces were ambushed in close quarters. They were unable to use air and artillery support due to the close engagement of the North Vietnamese, the American forces were badly defeated, suffering an over-50% casualty rate before being extricated from the battle. Both sides, therefore, were able to claim victory in the battle.
Passage 2:Behavioral neuroscience applies the principles of neurobiology, to the study of physiological, genetic, and developmental mechanisms of behavior. Cognitive inhibition is caused by several different interacting biological factors. The first is the existence of inhibitory neurotransmitters, or chemicals emitted by brain cells to both communicate and inhibit communication between each other. "GABA, an inhibitory transmitter substance that has been implicated in certain simple behavioral measures of inhibition and the control of aggressive behavior, was discovered in the cerebral cortex in substantial quantities". Given the cerebral cortex's importance in many brain functions such as memory and thought, the presence of the inhibitory substance GABA supports the cognitive inhibition processes that go on in this area of the brain. Serotonin and dopamine, which can play inhibitory roles as well, are present in the brain in large quantities. All three of these neurotransmitters are capable of "blocking" the transmissions between neurons, which can ultimately result in cognitive inhibition. In addition, the presence of inhibitory connections in the central nervous system has been firmly demonstrated (Eccles, 1969). A process known as lateral inhibition, which involves the capacity of an excited neuron to reduce the activity of its neighbors, is integral in the biology of cognitive inhibition. It provides much of the neural background behind it and explains what exactly is going on at the cellular level.
Passage 3:The Dangerous Liaisons is an opera in two acts and eight scenes, with music by Conrad Susa to an English libretto by Philip Littell. It is based on the novel Les Liaisons dangereuses by Pierre Choderlos de Laclos. The opera has set numbers with recitative and spoken dialog. It is set in France in the 18th century. The opera received its first performance by the San Francisco Opera on 10 September 1994, with stage direction by Colin Graham and Donald Runnicles as the conductor. The world-premiere cast included Thomas Hampson as Valmont, Frederica von Stade as Merteuil, David Hobson as Chevalier de Danceny, Renee Fleming as Tourvel and Mary Mills as Cecile de Volanges. The opera was performed at Washington Opera in March 1998. It was also aired on the American PBS television network's Great Performances, a video recording of which was also made. Albany Records released an audio recording of a performance by Manhattan School of Music Opera Theater in 2016.
