In this task, you're given a passage, further information available on a particular linked term from the statement, and a question. Your job is to generate the answer to the question by using the information provided. If there is no clear answer obtainable, output 'none'.

Ex Input:
Passage: Free-agent goaltender Jeff Hackett was signed from the Boston Bruins to replace Roman Cechmanek and challenge backup Robert Esche for the number one spot in 2003–04, but Hackett was forced to retire in February due to vertigo. During the course of the season, serious injuries suffered by both Jeremy Roenick (broken jaw) and Keith Primeau (concussion) in February forced the Flyers to trade for the Chicago Blackhawks' Alexei Zhamnov, who filled in well and kept the Flyers afloat. Esche entrenched himself as starter and remained in that position even after the Flyers re-acquired Sean Burke from the Phoenix Coyotes, as the Flyers clinched the Atlantic Division title over the New Jersey Devils on the last day of the season.

Ex Output:
Answer: none

Passage: After Landau moved to the Kapitza institute in Moscow (to avoid arrest for comparing Stalinism to Nazism), Pomeranchuk also moved there, working for the tanning industry. He returned to Leningrad in 1938, lecturing, completing his Ph.D. and becoming employed as a junior scientist. He joined the Lebedev Institute of the Academy of Sciences of the USSR in Moscow as a senior scientist in 1940. In 1941 the institute was evacuated to Kazan. Under Abraham Alikhanov, he studied cosmic rays in Armenia from 1942. In 1943, he transferred to Laboratory No.2 under Igor Kurchatov as part of the Soviet project to develop nuclear weapons. Alikhanov founded Laboratory No.3 (which became the Institute for Theoretical and Experimental Physics (ITEP)) and Pomeranchuk worked there from 1946 (and for the rest of his life), founding and leading the Theoretical department, as well as being Professor of Theoretical Physics at the Moscow Mechanical Institute where students admired his infectious enthusiasm for his subject. Rudolf Peierls was consoled by the fact that it was "very clever Pomeranchuk" - and no-one else - who corrected his 1/T law for heat conduction in high-temperature condensed matter physics. His work in the 1940s was dominated by neutron research and his manuscript with Akhiezer was the basic guide for Soviet nuclear reactor construction. In 1950, he published a paper suggesting that the entropy of helium-3 as a liquid was less than as a solid. In 1950, Pomeranchuk received an order from Josef Stalin to go to Arzamas-16, located in the closed city of Sarov, Nizhny Novgorod region, to work on Soviet nuclear weaponry. Missing his family and his 'hobby physics' problems, he was advised not to apply for a revocation but wait until the order was "forgotten." He returned to ITEP within a year. He continued enthusiastically with work on quantum field theory and S-matrix theory, particle collisions and Regge theory, the latter in vigorous collaboration with Vladimir Gribov. His last paper on Regge theory was published posthumously. For his work, Pomeranchuk was twice awarded the Stalin Prize (1950, 1952). He was elected a corresponding member of the Academy of Sciences of the USSR in 1953 and full member in 1964.

Answer: 72

Passage: The Turkel Commission (officially The Public Commission to Examine the Maritime Incident of 31 May 2010) is an inquiry set up by Israeli Government to investigate the Gaza flotilla raid, and the Blockade of Gaza. It is led by Israeli retired Supreme Court Judge Jacob Turkel. The other initial members of the commission were former President of the Technion and military expert, Amos Horev, and professor of international law, Shabtai Rosenne, who died in September 2010. The probe was overseen by two International observers: William David Trimble, former Leader of the Northern Irish Ulster Unionist Party and Northern Irish First Minister, a Nobel Peace Prize laureate, and Canadian former military judge Ken Watkin.
