Question
- A. To control the shape of the lens
- B. To carry impulses from the eye to the brain
- C. To support the eye structure
- D. To regulate the size of the pupil
Answer
The correct option is To carry impulses from the eye to the brain. This answer is correct because it matches the approved learning objective to describe the sclera as the tough supporting outer layer of the eye in the subtopic The eye (biology only).
Explanation
The correct option is To carry impulses from the eye to the brain. To carry impulses from the eye to the brain is correct because it directly supports the approved learning objective to describe the sclera as the tough supporting outer layer of 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 Sclera's Function
Students often describe the sclera as just a protective layer without mentioning its toughness and support role.
Emphasize that the sclera is not only a protective layer but also a tough supporting structure that maintains the shape of the eye.
