A psychologist reviews long-term developmental records for three children. The table shows the age at which each child first demonstrated four abilities.
| Child | Reasoned about a hypothetical situation | Searched for a fully hidden object | Conserved number after counters were spread out | Used one object to represent another in play |
|---|---|---|---|---|
| A | 11 years 9 months | 9 months | 7 years 4 months | 2 years 3 months |
| B | 12 years 2 months | 11 months | 8 years | 2 years 8 months |
| C | 11 years 3 months | 8 months | 6 years 11 months | 2 years 1 month |
Using the information in the table, state one conclusion Piaget would draw about the order of the four stages and one conclusion he would draw about the ages at which children reach them.
