You will be given a definition of a task first, then some input of the task.
In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

Question: How old was Graham Pollard when Terry Belanger began his fellowship in England? Passage:Born in 1941, Belanger attended public schools in Bristol, Connecticut. He has degrees from Haverford College (A.B., 1963) and from Columbia University (M.A., 1964; Ph.D., 1970), where he studied under James L. Clifford, Allen T. Hazen, and John H. Middendorf. Between 1966 and 1971, while working on his dissertation on aspects of the 18th-century London book trade, he taught advanced prose composition courses at the Columbia University School of General Studies, an activity leading to the 1972 publication of The Art of Persuasion, a writing manual co-authored with J. Steward LaCasce. While in England on a Columbia traveling fellowship in 1968–69, he revised the book production sections of the 18th-century volume of the New Cambridge Bibliography of English Literature (NCBEL), working with Graham Pollard, who had compiled the original sections for the first edition of CBEL, published in 1940. With Jane Marla Robbins, he co-authored and co-directed a one-character play starring Robbins called Dear Nobody, based on the life of the 18th-century diarist and novelist, Fanny Burney. The play ran Off-Off-Broadway in 1968; it later had a five-months' Off-Broadway run at the Cherry Lane Theatre in 1974.
