Answer to Question 1

4
The stimulation of the trigeminal nerve (CN V) causes the corneal reflex, a protective blink. Cranial nerves II, III, or IV do not control the corneal reflex.

Answer to Question 2

2
The lacrimal gland moistens the eye by producing and distributing tears to lubricate the eye. The lacrimal gland does not cover the eye for protection, help the eye keep its shape, or provide blood to the eye.
