Which artistic movement emerged in America in the 1920s focusing on precision and machine influence?

The artistic movement that emerged in America during the 1920s, focusing on precision and the influence of machinery, is Precisionism. This movement is characterized by its emphasis on clean lines, geometric forms, and detailed representations of industrial subjects, such as factories, machinery, and urban landscapes. Precisionists sought to capture the modern American experience and celebrated the advancements in technology and industry, often portraying them with a sense of clarity and order.

In contrast, other movements listed do not align with the characteristics of Precisionism. Yoruba Art is a traditional African art form that is rich in cultural and spiritual significance but is not related to the American artistic landscape of the 1920s. Impressionism, which originated in the late 19th century in France, focused on capturing light and momentary effects rather than the precision of form and machine influence. Abstract Expressionism emerged in the mid-20th century and was characterized by spontaneous and abstract forms, distancing itself from the representative and machine-influenced aspects of Precisionism. Therefore, Precisionism is the clear choice as it encapsulates the themes of precision and the mechanical influence prevalent in American art during that decade.
