Which statement most accurately describes Gertrude Stein's influence within American modernism?
Explanation
Gertrude Stein was a key figure among American expatriates in Paris, significantly shaping the cultural and artistic environment of that community. While she inspired many modernist poets, her primary contribution was her leadership within the émigré circle rather than merely being a muse. She did not support a toned-down modernism nor did she oppose avant-garde trends.
