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'.

Example Input: Passage: Golubić completed his primary education in Stolac, before relocating to Sarajevo to attend high school. In 1908, he moved to Belgrade for post-secondary studies, studying law at the University of Belgrade. Some of Golubić's classmates and contemporaries later recounted that Golubić was recruited by the Russian secret police, the Okhrana, in his youth. The historian Vladimir Dedijer later consulted the records of the Hoover Institution in an attempt to verify this claim, to no avail. Golubić did join Young Bosnia (), a multi-ethnic youth organization agitating for the separation of Bosnia and Herzegovina from Austria-Hungary. The organization's membership was around 70 percent Serb, 20 percent Bosnian Muslim and 10 percent Croat. Following the outbreak of the Balkan Wars in November 1912, Golubić joined the volunteer Chetnik detachment of Major Vojislav Tankosić. As part of their training, Tankosić ordered that Golubić and the other volunteers jump into the Sava from a railway bridge, "just to see whether you are going to fulfill all my orders."

Example Input: Passage: Born the son of Colonel Arthur Hare Vincent and Elizabeth Rose Manson and educated at Wellington College and the Royal Military Academy, Woolwich, Vincent was commissioned into the Royal Artillery as a second lieutenant on 24 July 1891. He was promoted to lieutenant on 24 July 1894 and to captain on 13 February 1900. He served with the China Expeditionary Force in late 1900 and then in the Second Boer War in South Africa. Following the end of the war, Vincent left Point Natal for India on the SS Ionian in October 1902 with other officers and men of the J Battery Royal Horse Artillery, and after arrival in Bombay, was stationed in Meerut, Bengal Presidency. In 1903, Vincent was sent to Tokyo to learn Japanese: he served as British military attaché with the Japanese Army during the Russo-Japanese War and, from 1 March 1904, was attached to the 2nd Division of the First Japanese Army in Manchuria.

Example Input: Passage: A solar cell, or photovoltaic cell (PV), is a device that converts light into electric current using the photovoltaic effect. The first solar cell was constructed by Charles Fritts in the 1880s. The German industrialist Ernst Werner von Siemens was among those who recognized the importance of this discovery. In 1931, the German engineer Bruno Lange developed a photo cell using silver selenide in place of copper oxide, although the prototype selenium cells converted less than 1% of incident light into electricity. Following the work of Russell Ohl in the 1940s, researchers Gerald Pearson, Calvin Fuller and Daryl Chapin created the silicon solar cell in 1954. These early solar cells cost US$286/watt and reached efficiencies of 4.5–6%. In 1957, Mohamed M. Atalla developed the process of silicon surface passivation by thermal oxidation at Bell Labs. The surface passivation process has since been critical to solar cell efficiency.
