Problem:Question: What is the population of the city where Schchapov earned his bachelor's degree? Passage:Afanasiy Shchapov was born in the village of Anga some 210 miles from Irkutsk, into a family of a Russian sexton and Buryat woman. Educated in Irkutsk, he moved to Kazan and became a student at Kazan Theological Academy (1852–1856). Upon receiving his Bachelor's degree, Shchapov began to deliver lectures on Russian history at his alma mater (1856–1860) and later at Kazan University (1860–1861). He also studied the Solovetsky Monastery library, which had been evacuated during the Crimean War to Kazan. Fascinated with the Solovetsky Uprising, Shchapov started writing articles about the Raskol and Old Believers. On April 16, 1861, he delivered a revolutionary speech dedicated to the victims of the Bezdna Unrest, after which he was arrested and escorted to St.Petersburg. After the investigation, Shchapov was dismissed as a teacher and appointed to the Ministry of the Interior as an official in charge of the sectarian affairs. In 1862, he was discharged and placed under police surveillance.
