These were so hard.
I got number 23 right at first, but wrong after a blind review. I don't understand why answer choice D is not a necessary assumption. Isn't it important that the brains of twins aren't any more likely to suffer from schizophrenia than a non-twin brain? Shouldn't that be of utmost important to ensure the conclusion about brains in general is valid?
But more confusing to me was 24. How in the heck can we find most of the answers to be "could be true" based on the stimulus? There is no mention of any of the answer choices, like (B) being able to control it with medication, but not cure it. Where is that even implied in the stimulus? Or susceptibility in answer (A). I can't find a logical string that ties these answers together.

Thanks! This is a great feature!!
