I want to know the answer to the following question:
Which Duchamp presentation was displayed in the 1912 Salon des Independants?
All the background I'm provided with is that "The subsequent 1912 Salon des Indépendants was marked by the presentation of Marcel Duchamp's Nude Descending a Staircase, No. 2, which itself caused a scandal, even amongst the Cubists.". Is that enough to answer the question?
