I want to know the answer to the following question:
How many communes of the outer suburbs are included in the metropole?
All the background I'm provided with is that "It includes the City of Paris, plus the communes, or towns of the three departments of the inner suburbs; Hauts-de-Seine, Seine-Saint-Denis and Val-de-Marne; plus seven communes in the outer suburbs, including Argenteuil in Val d'Oise and Paray-Vieille-Poste in Essonne, which were added to include the major airports of Paris.". Is that enough to answer the question?
Answer: yes
