Passage Five
Theories accounting for the physical process of color vision have undergone many changes since 1801, when Thomas Young first suggested that three types of cone in the retina respond to stimulus from red, green and blue light, or a mixture of these three basic colors. This concept of "additive" color has been retained with modifications made, as new discoveries of the eye’s functions have been uncovered. Today, the most popular theory is that there are color opponent cells in the eye that work to excite response to one basic color and inhibit another, while achromatic cells respond to whiteness or darkness. The interactions between these cells produce the huge range of colors that we see.
When it comes to naming these colors, however, an entirely different process takes over language. At one stage it was believed that language defined how one viewed the world, by restricting perceptions to terms available within each language. T

C. They discovered that people with few color terms could see as well as people with many color terms.
D. They discovered that people with fewer color terms could actually see fewer colors.
