I want to know the answer to the following question:
Was Duchamp's work considered controversial when displayed in 1912?
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?
Answer: yes
