Question: What university is Anthony Marten's college part of?

full_context: Document 1: John, King of England: Shortly after his birth, John was passed from Eleanor into the care of a wet nurse, a traditional practice for medieval noble families. Eleanor then left for Poitiers, the capital of Aquitaine, and sent John and his sister Joan north to Fontevrault Abbey. This may have been done with the aim of steering her youngest son, with no obvious inheritance, towards a future ecclesiastical career. Eleanor spent the next few years conspiring against her husband Henry and neither parent played a part in John's very early life. John was probably, like his brothers, assigned a magister whilst he was at Fontevrault, a teacher charged with his early education and with managing the servants of his immediate household; John was later taught by Ranulph Glanville, a leading English administrator. John spent some time as a member of the household of his eldest living brother Henry the Young King, where he probably received instruction in hunting and military skills.

Eton now co-sponsors a state sixth-form college in Newham, a deprived area of East London, called the London Academy of Excellence, opened in 2012, which is free of charge and aims to get all its students into higher education. In September 2014, Eton opened, and became the sole educational sponsor for, a new purpose-built co-educational state boarding and day school for around 500 pupils, Holyport College, in Maidenhead in Berkshire, with construction costing around £15 million, in which a fifth of places for day pupils will be set aside for children from poor homes, 21 boarding places will go to youngsters on the verge of being taken into care, and a further 28 boarders will be funded or part-funded through bursaries.
Document 4: History of Columbia University: Columbia University in New York City, United States, was founded in 1754 as King's College by royal charter of King George II of England. It is the oldest institution of higher learning in the state of New York and the fifth oldest in the United States. The period leading up to the school's founding was marked in controversy, with various groups competing to determine its location and religious affiliation. Advocates of New York City met with success on the first point, while the Church of England prevailed on the latter. However, all constituencies agreed to commit themselves to principles of religious liberty in establishing the policies of the College.

At the magnificent banquet to celebrate her father's elevation, Anne took precedence over the Duchesses of Suffolk and Norfolk, seated in the place of honour beside the King which was usually occupied by the Queen.

Document 12: Royal assent: Before the reign of Henry VIII, the sovereign always granted his or her assent in person. The sovereign, wearing the Imperial State Crown, would be seated on the throne in the Lords chamber, surrounded by heralds and members of the royal court—a scene that nowadays is repeated only at the annual State Opening of Parliament. The Commons, led by their speaker, would listen from the Bar of the Lords, just outside the chamber. The Clerk of the Parliaments presented the bills awaiting assent to the monarch, save that supply bills were traditionally brought up by the speaker. The Clerk of the Crown, standing on the sovereign's right, then read aloud the titles of the bills (in earlier times, the entire text of the bills). The Clerk of the Parliaments, standing on the sovereign's left, responded by stating the appropriate Norman French formula.

Mallet was Vice-Chancellor of the University of Cambridge, in 1536 and in 1540. The college was dissolved by Henry VIII in 1546.
