I want to know the answer to the following question:
Between what years did cubism begin?
All the background I'm provided with is that "The first organized group exhibition by Cubists took place at the Salon des Indépendants in Paris during the spring of 1911 in a room called 'Salle 41'; it included works by Jean Metzinger, Albert Gleizes, Fernand Léger, Robert Delaunay and Henri Le Fauconnier, yet no works by Picasso or Braque were exhibited.". Is that enough to answer the question?
Answer: no
