I want to know the answer to the following question:
By what group was Amadeo de Souza-Cardoso most heavily influenced by?
All the background I'm provided with is that "The 20th century saw the arrival of Modernism, and along with it came the most prominent Portuguese painters: Amadeo de Souza-Cardoso, who was heavily influenced by French painters, particularly by the Delaunays.". Is that enough to answer the question?
