Asked by researchers to sort objects by shapes, most toddlers in a large study had no trouble doing so. When subsequently told to sort by color, the toddlers seemed to have difficulty following the new rule and almost invariably persisted within their first approach. The researchers suggest such falilures to adapt to new rules often result from insufficent development of the prefrontal cortex in toddlers. The cortex is essential for functions like adapting to new rules, yet is slow to mature, continuing to develop right into adolescence.
which one is most supported by the information?
C. Certain kinds of behavior on the part of toddlers may not be willfully disobedient.
E. Skills at adapting to new situations is roughly proportional to the level of development of the prefrontal cortex.
I chose E and the right answre is C. I don't have problem understanding why C is right, but I am unable to convince myself why E is not right.
"Proportional" kills it. The stimulus only states that the two are correlated. One needs a heck of more specific quantitative evidence to draw such a narrow conclusion that they are proportionally correlated.
