Input: Question: Which college that offered Walker a scholarship is the oldest? Passage:As the schools in Eatonton were segregated, Walker attended the only high school available to blacks: Butler Baker High School. She went there to become valedictorian and enrolled in Spelman College in 1961 after being granted a full scholarship by the state of Georgia for having the highest academic achievements of her class. She found two of her professors, Howard Zinn and Staughton Lynd, to be great mentors during her time at Spelman, but both were transferred two years later. Walker was offered another scholarship, this time from Sarah Lawrence College in New York, and after the firing of her Spelman professor, Howard Zinn, Walker accepted the offer. Walker became pregnant at the start of her senior year and had an abortion; this experience, as well as the bout of suicidal thoughts that followed, inspired much of the poetry found in Once, Walker's first collection of poetry. Walker graduated from Sarah Lawrence in 1965.
