Answer: "Up close, she is able to see the painting's details most clearly because her lens focuses light intensely onto her blind spot."
This statement above DOES NOT identify the correct structure were light is focused so we can see clearly.
Explanation: "up close" means to be closer to an image so that you can view it clearly.
The blind spot of the eye is a small part of the optic nerve, which is the visual field of each eye where there are no photoreceptors (rods or cones), and therefore images are not formed in this portion of the eye. When light falls in this portion of the eye, images won't be formed, because the photoreceptors that forms the image for the brain to interpret are not present in that portion.
For example, after being exposed to a bright light, we find it difficult to detect images immediately, because the retina has adjusted for light to fall on the blind spot.
The statement in that paragraph is wrong because her eyes can't detect any image that fall on the blind spot, so therefore the brain will not have any image to interpret, which makes it impossible for her to see clearly
