The question asks:
At what state of development do children have the cognitive skills to be able to:
1. Repeat behaviours that bring about pleasure
2. Classify objects into two categories at the same time
3. Place objects in quantitative sequence (e.g. tallest to shortest)
4. Understand concepts of right and wrong
5. Able to recall past events and anticipate future events
6. Make repetitive voluntary movements, such as opening and closing fingers
7. Begin searching for objects that are hidden
8. Recall past events and anticipate future events
9. Express their thoughts verbally
