Final answer:
John Donne did not graduate from Cambridge University and Oxford University due to his refusal to take the Oath of Supremacy.
Step-by-step explanation:
John Donne, the renowned English poet and cleric, failed to graduate from two prominent institutions. He was enrolled at both Cambridge University and Oxford University, but did not receive a degree from either due to his refusal to take the Oath of Supremacy, which declared the monarch as the head of the Church of England. During the time Donne attended these universities, it was required for graduation. Although he did not graduate, Donne's education laid the foundation for his rich literary career and his eventual rise to become the Dean of St. Paul's Cathedral in London.
