Final answer:
The term 'Impressionism' originated from criticism of Monet's painting Impression, Sunrise, not Manet's work. It is false that it was derived from a critic's comment specifically about a Manet painting.
Step-by-step explanation:
The statement that the name "Impressionism" derives from a critic's derogatory remark about a painting by Édouard Manet is false. The term "Impressionism" actually comes from a painting by Claude Monet titled Impression, Sunrise (Impression, soleil levant). A critic disparaged Monet's work as merely an 'impression,' and the artists associated with this style of painting, including Monet, began to adopt the term Impressionists. The movement is characterized by a focus on the visual impression created by light and color, and a style that includes short, broken brush strokes to depict the transitory effects of light on subjects, often painted en plein air.
