I would like to clarify the meaning of the statement and provide you with a correct answer:
The avant-garde style in Germany before the First World War and continued to be popular afterward is known as Expressionism. Expressionism was a cultural movement that emphasized expressing emotions and feelings rather than representing the external world in an objective manner. It was characterized by bold colors, distorted forms, and a focus on the inner turmoil and psychological states of the artist.
Here's a breakdown to help you understand the concept better:
1. Avant-garde style in Germany before WWI: Expressionism
2. Characteristics of Expressionism: Emphasis on emotions, bold colors, distorted forms, and psychological depth
3. Continued popularity: Expressionism remained popular post-WWI due to its impactful and emotional nature.
Therefore, the correct answer to the question is Expressionism.
