Teacher: Now, understand the problem? Solve this instance: Question: Which US President that McNamara served under as US Attorney for Vermont lived the longest? Passage:McNamara was a native of Fair Haven, Vermont, and attended the schools of Fair Haven. He graduated from College of the Holy Cross in 1915, studied law with a Vermont attorney, and attended Harvard Law School. Leaving law school early to enter the military for World War I, McNamara served in the United States Army and attained the rank of sergeant as a member of the 87th Division. After leaving the Army, McNamara was admitted to the bar and began to practice law in Burlington, Vermont. He became active in politics as a Democrat, and served as Burlington's municipal court judge from 1921 to 1923. After unsuccessful runs for Vermont Attorney General and the U.S. House, in 1933 McNamara was named US Attorney for Vermont. He held the post through the administrations of Democrats Franklin Roosevelt and Harry Truman, and resigned after Republican Dwight Eisenhower became president.
