If PPE -> SWA If Poet -> PPE Thus: No PRE Depends on Precise Understanding.
If this feels like a leap, that is because it is. First, we can't exactly say that readers having a precise understanding is the opposite of SWA, maybe an author used a word ambiguous but I, the reaser, mistakenly have a precise understanding. Additionally, the idea of enjoyment comes out of left field. To make this argument valid, we need an answer choice that connects SWA with both enjoyment and precise understanding.
(C) does exactly this, it tells us that if SWA, then no PRE depends on Precise Understanding
