Task: Question Generation
Input (English): Construction of the chapel, originally intended to be slightly over twice as long, with eighteen - or possibly seventeen - bays (there are eight today) was stopped when Henry VI was deposed. Only the Quire of the intended building was completed. Eton's first Headmaster, William Waynflete, founder of Magdalen College, Oxford and previously Head Master of Winchester College, built the ante-chapel that finishes the Chapel today. The important wall paintings in the Chapel and the brick north range of the present School Yard also date from the 1480s; the lower storeys of the cloister, including College Hall, had been built between 1441 and 1460.
Output (English): Who was Eton's first Headmaster?
