Which Piaget stage extends from adolescence into adulthood?

• A. Sensorimotor
• B. Formal Operational
• C. Preoperational
• D. Concrete Operational

Answer: (B)

The main idea tested is how thinking becomes abstract and capable of hypothetical reasoning as people mature. The stage that extends from adolescence into adulthood is the Formal Operational stage, where thinking develops the ability to reason about possibilities, use abstract concepts, and plan systematic investigations or hypotheses. In earlier stages, thinking is tied to concrete experiences: sensorimotor covers infancy, preoperational involves symbolic but not logical thought, and concrete operational handles logical thinking about concrete objects and events. In the Formal Operational stage, you can tackle abstract problems, such as algebra or hypothetical scenarios, and evaluate outcomes without needing tangible objects in front of you.
