You will be given a definition of a task first, then some input of the task.
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.

Question: What was the population of Cannacht the year that Fitzgibbon was spared his life for his swift surrender of the castle, but subsequently lost his lands at Ardfinnan and was transplanted to Connacht? Passage 1:On Saturday 2 February 1650 major general Henry Ireton, who was accompanying Oliver Cromwell in his conquest of Ireland, had neither the boats or sufficient weather in order to make a crossing of the river Suir with his army and subsequently headed for the bridge at Ardfinnan to gain another crucial pass over the river Suir, second to the pass at Carrick. In view of taking hold of the strategically placed castle which guarded this crossing from high above, he waited until around four o'clock the next morning to attempt a siege. Defending the castle from the Parliamentarians with a small force of soldiers was David Fitzgibbon (the White Knight), Governor of Ardfinnan Castle for Charles II. With cannons placed on a hill opposite the castle, Ireton bombarded it's once impenetrable walls until there was a large breakthrough after about 8 shots and then proceeded to kill about thirteen of the out-guard and lost only two of his men with about ten wounded. After this the castle was promptly surrendered to the New Model Army who would use it as a garrison throughout their time in Ireland. Fitzgibbon was spared his life for his swift surrender of the castle, but subsequently lost his lands at Ardfinnan and was transplanted to Connacht in 1653. Guns, ammunition and other supplies arriving at Youghal would be brought over the river Blackwater at the pass at Cappoquin and then finally over the river Suir at Ardfinnan to reach the rest of the army in Tipperary. With the end of the Cromwellian campaign of Ireland, the leaving Parliamentarian troops slighted Ardfinnan castle which partially left it in ruins.
Passage 2:Berlyand was born in Kharkov on September 20, 1957. His father, Viktor Berlyand, was a mechanical engineer, and his mother, Mayya Genkina, an electronics engineer. Upon his graduation in 1979 from the department of mathematics and mechanics at the National University of Kharkov, he began his doctoral studies at the same university and earned a Ph. D. in 1984. His Ph. D. thesis studied the homogenization of elasticity problems. He worked at the Semenov Institute of Chemical Physics in Moscow. In 1991 he moved to the United States and started working at Pennsylvania State University, where he has served as a full professor since 2003. He has held long-term visiting positions at Princeton University, the California Institute of Technology, the University of Chicago, the Max Planck Institute for Mathematics in the Sciences, Argonne and Los Alamos National Laboratories. His research has drawn support from the National Science Foundation(NSF), NIH/NIGMS, the Applied Mathematics Program of the DOE Office of Sciences, BSF (the Bi-National Science Foundation USA-Israel) and the NATO Science for Peace and Security Section. Berlyand has authored roughly 100 works on homogenization theory and PDE/variational problems in biology and material science. He has organized a number of professional conferences and serves as a co-director of the Center for Mathematics of Living and Mimetic Matter at Penn State University. He has supervised 17 graduate students and ten postdoctoral fellows.
Passage 3:Francisco "Chico" Serra (born 3 February 1957 in Sao Paulo) is a racing driver from Brazil. He won the 1979 British Formula 3 Championship. He participated in 33 Formula One World Championship Grands Prix for Fittipaldi and Arrows, debuting on 15 March 1981. He made 18 starts, not qualifying for the remaining fifteen races, although he ought to have started as the reserve in the 1982 Swiss Grand Prix. However, Ferrari withdrew Patrick Tambay's entry so late that Serra was not allowed to take part. Serra scored one championship point, for finishing sixth in the 1982 Belgian Grand Prix. After qualifying for the 1982 Canadian Grand Prix, Serra and countryman Raul Boesel had a short scuffle. Serra was furious at Boesel for blocking his last flying lap after waving Keke Rosberg by. Boesel denied that this was intentional. Serra made one CART Champ Car start in 1985 at the Portland International Raceway for Ensign Racing but suffered an engine failure.
