I was thinking that too. Possibly labelling the structure of the eye or distinguishing between different types of muscle. In last years paper, there was labelling of a neurone.

I mean some of the question were very hard but others were ok. I have found the first question very hard about the eye.

I said the root, literally just because it was the only area really mentioned and the fact that bacteria had to destroy other bacteria and fungi so suggesting that it was an area that was basically infested?

I was rushing to finish that question and didn't really read the question properly but I saw the mean was 6.3. Just making sure I didn't miss something else in the question.
