Answer: b. James A. Garfield.
Explanation: From to 1851 to 1854 he studied at the Western Reserve Eclectic Institute [later named Hiram College] in Hiram, Ohio. He then moved to Williams University in Williamstown, Massachusetts, where he was a member of the Delta Epsilon brotherhood. He graduated in 1856 as an exceptional student who excelled in all subjects except chemistry. He later taught classical languages at the Eclectic Institute during the academic year 1856-1857 and was appointed director of the institute from 1857 until 1860. Garfield decided that academic life was not for him and he studied law on his own. He was admitted to the Ohio Bar in 1860. As an anecdote, it should be noted that he was an amateur mathematician and published an original proof of the Pythagorean Theorem [New England Journal of Education]
