Example Input: Question: In what year did Ostashenko's country join the first world war? Passage:Ostashenko was born on 19 June 1896 in the village of Bolshaya Lyubshchina, Yanovichskoy volost, Vitebsky Uyezd, Vitebsk Governorate to a peasant family. He graduated from four grades at a gymnasium. During World War I, he was mobilized for military service on 7 August 1915, being sent to the 4th Company of the Reserve Battalion of the Petrograd Lifeguard Regiment in Petrograd. With the battalion, he fought with the Southwestern Front between July 1916 and February 1917, then returned to Petrograd before being demobilized on 13 March 1918. In July, he volunteered for the Red Army, serving in the Vitebsky Uyezd military commissariat as a clerk and instructor organizer. From May 1919 Ostashenko served as a Red Army man and political soldier – a Communist mobilized to conduct political work in the army – in the march battalion of the Vitebsk Reserve Regiment. From July he served as an assistant platoon commander in the 84th Rifle Regiment of the 10th Rifle Division, which fought against the Northwestern Army near Petrograd as part of the 15th Army of the Western Front. He entered the Smolensk Commanders' Infantry Courses in November and upon graduation in June 1920 became a platoon commander in the Rzhev-based 2nd Reserve Regiment. This assignment proved to be brief and a month later, Ostashenko became adjutant of the 4th Landing Detachment for armored trains with the Western Front. He fought with the detachment, which provided landing parties for armored trains, in the Polish–Soviet War and was wounded twice.

Example Input: Question: When was the first college that Rollo May attended founded? Passage:May was born in Ada, Ohio, on April 21, 1909. He experienced a difficult childhood when his parents divorced and his sister was diagnosed with schizophrenia. He was the first son of a family with six children. His mother often left the children to care for themselves, and with his sister suffering from schizophrenia, he bore a great deal of responsibility. His educational career took him to Michigan State University, where he pursued a major in English, but he was expelled due to his involvement in a radical student magazine. After being asked to leave, he attended Oberlin College and received a bachelor's degree in English. He later spent three years teaching in Greece at Anatolia College. During this time, he studied with doctor and psychotherapist Alfred Adler, with whom his later work shares theoretical similarities. He became ordained as a minister shortly after coming back to the United States, but left the ministry after several years to pursue a degree in psychology. He was diagnosed with tuberculosis in 1942 and spent 18 months in a sanatorium. He later attended Union Theological Seminary for a BD during 1938, and finally to Teachers College, Columbia University for a PhD in clinical psychology in 1949. May was a founder and faculty member of Saybrook Graduate School and Research Center in San Francisco.
