Based on this paragraph about the early career of John C. Young (pastor), after the resignation of which whom was Young offered the presidency of Centre College in Danville, Kentucky?

Context:
After he received a license to preach from the Presbytery of New York on March 7, 1827, Young's career in the ministry began following his graduation from Princeton. In 1828, he moved to Lexington, Kentucky, where he was appointed to the pastorate of McChord Presbyterian Church (now Second Presbyterian Church), founded in 1815 by James McChord, who was later elected as the first president of Centre College in Danville, Kentucky.

Centre's presidency became vacant in October 1830 when Gideon Blackburn resigned the office. At the recommendation of Archibald Alexander, principal of Princeton Theological Seminary, the college's trustees offered Young the position in a unanimous vote. He accepted and was inaugurated as the fourth president of Centre College on November 18, 1830, at the age of 27.<|im_end|>
