Which three statements describe the similarities between the art of georgia o'keeffe and edward weston?

Well, for starters, they both have a very unique art style. They both draw things mostly related to nature, and both artist's work are fairly simple. Georgia draws mostly floral art, while Edward draws things such as shell's, mushrooms, etc.

One big difference between the two is that Georgia paints using mainly bright colors, while Edward uses more black, white, and grey.

1. They are examples of Modernism and are often close-ups of natural objects.

2. They are abstract, with simplified lines and shapes.

3. Light and dark values in them help show an object's form.

I would say yes.  There is a balance of beauty with the surroundings, the harmony with the colors in the different details, the proportion could not be any more exquisite, and the movement is eye catching.
