TASK DEFINITION: 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'.
PROBLEM: Passage: The government of the Electorate of Hesse (Kurhessen) had begun building the Frankfurt–Bebra railway from Bebra in North Hesse to Fulda, Hanau and Frankfurt before its annexation by Prussia after the Austro-Prussian War of 1866. The project was completed by the Prussian state railways on 15 December 1868. Until the opening of the line south of the Main, trains from Bebra to Frankfurt had to use the North Main line and the Frankfurt City Link Line. On 15 November 1873 the new line south of the Main between Hanau and Frankfurt via Sachsenhausen and Offenbach was opened, including South Station (opened as Bebraer Bahnhof, "Bebra line" station) and Offenbach Hauptbahnhof. The South Main line is still the most important rail link connecting Frankfurt with Leipzig, Berlin and Hamburg.
 Link Information: The Austro-Prussian War or Seven Weeks' War Question: How many months did the war that preceded the building of the Frankfurt-Bebra railway last?

SOLUTION: Answer: 2

PROBLEM: 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.
 Link Information: Childhood to young adulthood: 1878–1899.Stalin was born in the Georgian town of Gori, then part of the Russian Empire and home to a mix of Georgian, Armenian, Russian, and Jewish communities. He was born on , and baptised on 29 December. Question: What age was Stalin when he gave Pomeranchuk an order to go to Sarov?

SOLUTION: Answer: 72

PROBLEM: Passage: After shakedown in the Caribbean Sea, Saint Paul departed Boston, Massachusetts, on 15 May 1945 and headed for the Pacific. From 8–30 June, she underwent training out of Pearl Harbor and sailed on 2 July to join Task Force 38 (TF 38). This fast carrier striking force completed replenishment at sea on 23 July and then proceeded to launching points for strikes against Honshū, Japan's largest island. From 24 July to 10 August, Saint Paul screened the carriers as they delivered heavy air strikes on Kure, Kobe, and the Tokyo area in southern Honshū, then at Maizuru and various airfields in northern Honshū. During this period, Saint Paul also bombarded industrial targets: first on textile mills at Hamamatsu during the night of 29 July, and then on 9 August at iron and steel works in Kamaishi, firing the war's last hostile salvo from a major ship. Typhoon warnings canceled air operations from 11–14 August. Then, those launched that morning were recalled, after peace negotiations gave promise of Japan's surrender. On 15 August, all offensive operations against Japan were stopped.
 Link Information: , the city has an estimated population of 228,030 Question: Which southern Honshū city is the most populous of the three that had heavy air strikes delivered on them between July 24 and August 10?

SOLUTION:
Answer: Tokyo
