The concrete operational stage is characterized by the ability to understand conservation, which means understanding that the amount of a substance remains the same even if its appearance is changed. In this scenario, Gilbert understands that even though his brother's sausage is sliced into more pieces, the overall amount of sausage remains the same. This ability to understand conservation is a hallmark of the concrete operational stage, which typically occurs between the ages of 7 and 12.
