Question
- A. It absorbs the light
- B. It refracts the light
- C. It reflects the light
- D. It transmits the light without change
Answer
The correct option is It refracts the light. This answer is correct because it matches the approved learning objective to describe the cornea as a transparent outer region that refracts light entering the eye in the subtopic The eye (biology only).
Explanation
The correct option is It refracts the light. It refracts the light is correct because it directly supports the approved learning objective to describe the cornea as a transparent outer region that refracts light entering the eye. This belongs to the subtopic The eye (biology only) within The human nervous system, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from The eye (biology only).
Common mistake
Misunderstanding the Cornea's Function
Students often describe the cornea only as a protective layer without mentioning its role in light refraction.
Emphasize that the cornea is not only a protective outer layer but also a transparent region that refracts light entering the eye, which is crucial for focusing images on the retina.
