An adolescent who hypothesizes and speaks in terms of possibilities may well be functioning in Piaget's cognitive stage of "formal operational thought".

Explanation:

The final stage of Jean Piaget's theory of cognitive development is formal operational thought and this stage starts from 11 or 12 years of age to adulthood.  When an individual reaches this stage, his/her thinking becomes innovative and creative enough to solve the issues or problems they are dealing with and they can solve different tasks assigned to them.
