Question: How long did the Siege of Boston last? Passage:The Battle of Lexington and Concord was the first conflict in the American Revolutionary War. On April 19, 1775, a force of British Army regulars marched from Boston to Concord to capture a cache of arms that was reportedly stored in the town. Forewarned by Samuel Prescott (who had received the news from Paul Revere), the colonists mustered in opposition. Following an early-morning skirmish at Lexington, where the first shots of the battle were fired, the British expedition under the command of Lt. Col. Francis Smith advanced to Concord. There, colonists from Concord and surrounding towns (notably a highly drilled company from Acton led by Isaac Davis) repulsed a British detachment at the Old North Bridge and forced the British troops to retreat. Subsequently, militia arriving from across the region harried the British troops on their return to Boston, culminating in the Siege of Boston and the outbreak of the war.

Question: How large is the city where Rollo May was born? 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.
