For anyone confused between A and E: the stim makes a claim and proceeds to follow it with But, clearly..., meaning that whatever is to follow is rejecting that initial claim. Answer A, now, doesn't make sense because it affirms what that initial claim is saying based on most people's understanding that babies have never learned vocab or read a dictionary; it also just fails to take into account the second sentence.

I guess something that has helped me a lot is being able to come into every stim with the preconceived notion that it probably has no real basis or credibility in the real world, so in order to properly answer it, I would have to actively not try and make connections, inferences, whatever that I might make in common conversation or everyday life. Hope this makes sense, apologies if not (it's 2am).
