Recent studies show exploratory play - the restless, unstoppable drive to push every button and pull every string - helps children discover how the physical world works. Their equally unstoppable "pretend" play - the parade of alternate identities, imaginary friends and wild fantasies - helps them work out all the possible ways that people would be. The picture that emerges from this research is that babies and young children are not so much defective as different from adults. They have equally complex and powerful, but very different minds and brains, suited to their distinctive evolutionary role. Babies are brilliant learners but terrible planners. They have fantastically creative and visionary imaginations, but absolutely no executive capacity.
They are the R & D guys and adults are the CEOs
The passage highlights the "quick learning” and "creative” abilities of children and the "good execution skills” of adults. Option (c) beautifully explains this relation by calling children the R&D guys and adults the CEOs as those roles suit their skill sets. Options (b) and (d) are outside the scope of the passage, and can thus be eliminated. Option (a) talks about "reverse metamorphosis” which is not very clearly talked about. Therefore, it is evident that answer option (c) is the most appropriate answer choice.
