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

The correct choice, Precisionism, refers to an American art movement that developed in the 1920s, characterized by its focus on clarity, precision, and the influence of machinery on modern life. This movement emphasized the representation of industrial landscapes and urban scenes with sharp lines, geometric forms, and attention to detail. Artists associated with Precisionism sought to capture the beauty found in modern environments, reflecting the technological advancements and industrialization of their time.

The other artistic movements mentioned, such as Yoruba Art, primarily relate to African artistic traditions that do not focus on the themes of industrialization or machine influence and predate the 1920s. Impressionism, originating in France in the late 19th century, is centered on the effects of light and color rather than precision and angularity in forms. Abstract Expressionism, which rose to prominence later in the mid-20th century, is characterized by a focus on spontaneity and emotional expression rather than the clear, stable forms found in Precisionism.
