Task: Question Generation
Input (English): Passage: The first comprehensive theories of management appeared around 1920. The Harvard Business School offered the first Master of Business Administration degree (MBA) in 1921. People like Henri Fayol (1841-1925) and Alexander Hamilton Church (1866-1936) described the various branches of management and their inter-relationships. In the early-20th century, people like Ordway Tead (1891-1973), Walter Dill Scott (1869-1955) and J. Mooney applied the principles of psychology to management. Other writers, such as Elton Mayo (1880-1949), Mary Follett (1868-1933), Chester Barnard (1886-1961), Max Weber (1864-1920), who saw what he called the "administrator" as bureaucrat, Rensis Likert (1903-1981), and Chris Argyris (born 1923) approached the phenomenon of management from a sociology perspective.
Output (English): How many years after the first comprehensive theories of management appeared did Harvard Business School offer the first Master of Business Administration degree?
