Imagine Mara, a scientist who studies color vision in a room where everything is black, white, or gray. Her screens display no colors. Still, she has learned every physical fact about human color perception, including facts beyond present scientific knowledge: wavelengths, retinal cells, neural signals, language, and behavior. She can predict what people will say when they see a ripe tomato.
One day, Mara leaves the room and sees red for the first time. Does she learn something? If the experience teaches her what red looks like, then complete physical information may seem to leave out a fact about conscious experience. Philosopher Frank Jackson made a version of this case famous as the knowledge argument.
The conclusion is disputed. Some philosophers say Mara gains new knowledge: she now knows a quality that descriptions could not provide. Others say she gains an ability, such as recognizing or imagining red, without discovering a new fact. Still others argue that she encounters an old physical fact through a new form of representation.
The thought experiment does not depend on whether such a total education is practically possible. Its extreme setup sharpens a distinction between describing a brain process and undergoing an experience. Yet the story alone does not announce which interpretation wins. Like a prism separating one beam, it divides meanings of “knowing” so they can be examined.

Question 1 of 4
What is the main idea of the passage?
The answer is B: The color-room thought experiment tests whether complete physical knowledge includes what a conscious experience feels like.
The setup and competing interpretations all concern whether experiential knowledge adds something to physical description.

Question 2 of 4
Why does the author compare the case to a prism?
The answer is C: The case separates several meanings of knowledge so each can be considered distinctly.
The final phrase directly explains the metaphor: one term, “knowing,” is divided into examinable meanings.
