I want to know the answer to the following question:
How many years was Francois Mitterrand in power?
All the background I'm provided with is that "Valéry Giscard d'Estaing began the Musée d'Orsay (1986); President François Mitterrand, in power for 14 years, built the Opéra Bastille (1985-1989), the Bibliothèque nationale de France (1996), the Arche de la Défense (1985-1989), and the Louvre Pyramid with its underground courtyard (1983-1989); Jacques Chirac (2006), the Musée du quai Branly.". Is that enough to answer the question?
Answer: yes
