The statements that describe similarities between the art of Georgia O'Keeffe and Edward Weston are:
- Light and dark values in them help show an object's form.
- They are examples of Modernism and are often close-ups of natural objects.
- They are abstract, with simplified lines and shapes.
The statement about objects being depicted in the center to create variety does not accurately describe their artistic approaches, as both artists tended to emphasize clarity and focus rather than variety in composition.
