Why is C correct? Why is E incorrect?

I'd like to understand this same question.

Hi @Ryan-Mahabir and @#JW, (E) is wrong because nowhere in the passage is "an accurate understanding of how primary perceptions function" brought up. Our primary perceptions do show up in the third paragraph, but our understanding of how they function does not. (C), on the other hand, refers to the front-to-back explanation of mirrors. There is direct textual support for the claims made in (C) in lines 42-45. Hope this helps.
