18. (C)
Question type: Inference
The argument explains how the difficulty toddlers have adjusting to new rules is related to the slow development of the frontal cortex. For inference questions, we are looking for an answer that is fairly provable based on the text.

(C) is not an answer we can predict, but it is fairly provable and therefore correct. Based on the information presented, we can see that some instances of toddlers not obeying rules are due to the lack of development in their prefrontal cortex, and therefore not due to their desire to be willfully disobedient.

(A) represents a misinterpretation of the text, and is not provable.
(B) is too extreme in what it concludes and therefore is not provable.
(D) introduces a relative argument that is not provable.
(E) is attractive, but goes beyond what the text states. We know that the development of the prefrontal cortex is important for adapting to new situations, but we don’t know if that connection is proportional.
