I want to know the answer to the following question:
Which technique did the Impressionists use to make their subjects simple forms?
All the background I'm provided with is that "The Impressionists had used a double point of view, and both Les Nabis and the Symbolists (who also admired Cézanne) flattened the picture plane, reducing their subjects to simple geometric forms.". Is that enough to answer the question?
Answer: yes
