I have highlighted what I feel is going to be necessary information from the passage. Our best answer is going to be answer choice A.Ĥ) We can get this information from the passage.

Out of all the answer choices listed, only the occipital cortex controls vision. The motor cortex functions to control and execute voluntary movement. Our senses gather information, and the somatosensory cortex processes these sensations. Like its name suggests, the somatosensory cortex processes somatic sensations. Answer choice A remains our best option because it controls vision. The temporal lobe controls hearing and some other speech functions. We can look at our other answers and dive further in the functions if we need to get into further detail. The occipital lobe controls vision, so right away we have a promising answer. We want the answer choice that’s related to viewing color, or vision in general. Answer choice D is going to be our best answer.ģ) To answer this question, we’ll look through the four answer choices presented and go through the functions of each. This correctly shows a continuous pattern and a steady increase from green to blue.This is identical to the graph in the passage and also shows the colors being perceived categorically.This is just the reverse of Figure 1 in the passage and shows the colors being perceived categorically (either green or blue).The baboons are able to distinguish between the colors. This answer choice incorrectly shows the percent of green responses do not change.The plot for baboons will be different we should see a continuum and a steady increase from green to blue. We perceive these colors categorically as either green or blue, while baboons do not. The fovea is related to color sensation, and that is where we’d want the most similarity in eye structure.Ģ) First part of our passage explained how humans abruptly switched from blue to green responses at a certain wavelength in the experiment. Answer choice C is going to remain our best option. Lens The lens is a transparent biconvex structure in the eye that, along with the cornea, helps to refract light to be focused on the retina.This sounds like the most relevant function to color perception so far. When you bring your gaze to an object to examine it intently in bright light, the eyes orient so that the object’s image falls on the fovea. Fovea The fovea is the region in the center back of the eye that is responsible for acute vision.Sclera The sclera is the white, outer layer of the eye.The blind spot you have in each eye corresponds to the optic disc. It is the point of exit for ganglion cell axons leaving the eye. Optic disc The optic disc is where the optic nerve connects to the retina, which you can see in the above image.We’ll have to judge which would be the most important when comparing the color perception of humans and baboons. 1) This question involves knowing the four structures of the eye listed in the answer choices.
