Of course, shoulder, the arm can make a circular arc, as can the hip joint. You really ought to look up words you don't know.

I have a hard time with this question:

During a windstorm, something is blown into your eye causing you discomfort. You immediately rub
your eye to try to remove the particle. What part of the eye might be irritated by this rubbing?
A. Optic nerve
B. Cornea
C. Sclera
D. Retina


I think it is D but not sure. I have all my answers on the paper but not sure if they are correct so this is why I am asking someone to check it.

Have you looked at a diagram of the eye?
