Answer:
"No, the longer sausage has more clay".
Step-by-step explanation:
In such a scenario, a child in Piaget's concrete operational stage would most likely say "No, the longer sausage has more clay". This is because in this (third) stage of Piaget's theory of cognitive development the individual child begins to use logical thought and rules which they apply to physical objects. In the child's mind in this scenario, since he physically sees one of the sausages as longer he believes that it has more amount of clay, therefore applying his set of learned rules that bigger means more.
