Reading the argument
Paint has an obvious teaching advantage: you can mix colors. Showing red and yellow becoming orange could teach something that two separate sheets of colored paper wouldn't show in the same way. So why prefer paper?
The author has a different lesson in mind: compare exactly the same color in different compositions. A particular pink might look different against one background than another. To isolate that effect, we want to keep the pink itself the same. The passage says paper makes that easier, while paint is difficult to mix identically and its applied texture can interfere.
Let's grant those differences. The remaining question is why this precise comparison matters for teaching students about color. Being able to repeat a shade isn't automatically an educational advantage; the comparison has to help students learn something relevant.
What we’re looking for
For the required assumption, look for that connection between what the material lets the teacher demonstrate and what the students need to learn.
Working the answers
- A
The argument doesn't require all paper textures to leave a color's effect unchanged. Teachers could choose pieces of paper with the same texture. Then they could use the repeatable color without relying on the sweeping claim that different textures never alter its effect.
- B
The advantage isn't that students fail to notice small differences in paper colors. It's that the teacher can readily reuse exactly the same color. We don't need paper differences to be harder to detect than paint differences for that advantage to exist.
- C
The teacher could hold lighting constant during the comparison. The argument doesn't depend on paper being less affected than paint when the lighting changes. We shouldn't turn every possible difference between the materials into a required assumption.
- DCorrect
Observing a color's impact in different contexts helps students learn about the use of color. This makes the precise comparison an educational benefit. Without that connection, the author has described something paper does well without showing why it is a reason to use paper when teaching this subject.
- E
The lesson is about color, not necessarily about the difference between paper and paint. Those materials are tools for reaching the learning goal. Students needn't learn a separate lesson comparing the tools in order to benefit from the demonstration the author recommends.
