Final answer:
The one reason not attributed to Cubism's influence on twentieth-century art is the emphasis on realistic representation. Cubism is known for multiple perspectives, the abstraction of forms, and influencing modern design, while realistic representation is the antithesis of Cubist principles.
Step-by-step explanation:
Cubism significantly influenced twentieth-century art and architecture for a variety of reasons, but one reason not attributed to Cubism is B. Emphasis on realistic representation. Cubism, pioneered by Pablo Picasso and Georges Braque, is known for its exploration of multiple perspectives simultaneously (A), the deconstruction and abstraction of forms (C), and its influence on modern architectural design (D). This movement deviated from realistic representation and instead focused on breaking objects into geometric shapes, reassembling them in abstract form, and taking advantage of the two-dimensional picture plane.
Cubism originated as a groundbreaking art movement in the early 20th century, transforming visual arts and influencing other spheres such as literature, music, and architecture. Rejecting conventional approaches, Cubist artists departed from one-point perspective and realistic depiction, embracing a multiplicity of viewpoints. They deconstructed objects into simplified geometric forms in a process known as geometric abstraction. Furthermore, through stages like analytical Cubism and synthetic Cubism, they explored the use of monochromatic color schemes and brighter colors, collages, and abstract space, challenging traditional perceptions of space and form.
